Background:

Fifth Lockheed Martin MUOS Secure Communications Satellite Completes Assembly, Enters System Test
 
SUNNYVALE, Calif., January 13, 2014 – The fifth Lockheed Martin [NYSE: LMT] Mobile User Objective System (MUOS) satellite for the U.S. Navy is entering its first system test faster than the previous build, now that integration is complete. Engineers and technicians recently mated its system module and core to the multi-beam assembly (MBA), which hosts 16 ultra-high frequency (UHF) antennas for distributed, global communications coverage.
 
The MBA’s antennas beam down coverage to Earth, with each covering thousands of miles of terrain. Supporting UHF satellite communications, MUOS will provide secure mobile users with assured communications, including the new capability of simultaneous voice, video and data.
 
“Our fifth MUOS satellite shows strong learning curve benefits. Compared to our last build, we are approximately 20 percent ahead of schedule,” said Iris Bombelyn, vice president of Narrowband Communications at Lockheed Martin. “We are continuously improving our manufacturing, test, launch and orbit operations to best serve the U.S. Navy and users that need secure, mobile voice and data communications.”
 
Designed and built by Lockheed Martin, the MUOS antenna rests on an A2100 bus, also built by Lockheed Martin, and uses a system module provided by General Dynamics. Together, the system enables communications coverage using the Wideband Code Division Multiple Access standard, providing a 10-fold increase in transmission throughput over the current UHF satellite system.
 
Lockheed Martin Space Systems, Sunnyvale, Calif., is the MUOS prime contractor and system integrator. The Navy's Program Executive Office for Space Systems, Chantilly, Va., and its Communications Satellite Program Office, San Diego, Calif., are responsible for the MUOS program.

Lockheed Martin’s MUOS Production Line Ships Fifth Secure Communications Satellite to Florida for May Launch (http://www.lockheedmartin.com/us/news/press-releases/2016/march/160302-ssc-muos-satellite-shipping.html)

MUOS-5 is third satellite to launch in 16 months for U.S. Navy’s Smart Phone-Like Network

On March 3, MUOS-5, the next satellite scheduled to join the U.S. Navy’s Mobile User Objective System (MUOS) secure communications network, arrived at Cape Canaveral after shipping from Lockheed Martin’s satellite manufacturing facility in Sunnyvale, California.


CAPE CANAVERAL AIR FORCE STATION, Fla., March 9, 2016 – The U.S. Navy and Lockheed Martin (NYSE: LMT) delivered the fifth Mobile User Objective System (MUOS) satellite to Cape Canaveral Air Force Station, Florida, on March 3, prior to its expected May launch.

The spacecraft will be the third MUOS satellite launched in a 16-month span, a cadence that demonstrates the production line concept put into place for the delivery of this five-satellite build.

MUOS-5 is the latest addition to a network of orbiting satellites and relay ground stations that is revolutionizing secure communications for mobile military forces. Users with operational MUOS terminals will be able to seamlessly connect beyond line-of-sight around the world and into the Global Information Grid. MUOS’ new capabilities include simultaneous, crystal-clear voice, video and mission data, over a secure high-speed Internet Protocol-based system, similar to today’s smart phones.

MUOS-5 will complete the Navy’s baseline constellation and serve as an on-orbit spare for the system, ensuring the network is always available to support U.S. and allied mobile forces.

“As MUOS-5’s launch approaches, MUOS-4 is preparing to begin operations on-station, enabling MUOS’ near-global coverage,” said Mark Woempner, program director of Lockheed Martin’s Narrowband Communications mission area. “We are proud that we will soon be providing our mobile forces access to the system’s enhanced communications capabilities from nearly anywhere, including further into polar regions than ever before.”

Lockheed Martin manufactured MUOS-5 at its Sunnyvale, California facility. For its trip to Florida the satellite was loaded aboard a C-5 Galaxy aircraft at nearby Moffett Federal Air Field by the 60th Air Mobility Wing of Travis Air Force Base. Astrotech Space Operations, a Lockheed Martin wholly-owned subsidiary in Florida, will complete MUOS-5’s pre-launch processing.

The satellite joins MUOS-1, MUOS-2, MUOS-3, and MUOS-4 already on orbit. All four required MUOS ground stations are complete. More than 55,000 currently fielded radio terminals can be upgraded to be MUOS-compatible, with many of them requiring just a software upgrade.

Once fully operational, the MUOS network will provide 16 times the capacity of the legacy ultra high frequency communications satellite system, which it will continue to support, and eventually replace.

At risk of derailing the thread (sorry), what kinda of dV was lost with those 6s of burn time?  I realize it can be quite a bit given that's supposed to be the lightest stack that first stage gets to push against.  I could calculate it myself but if you know it off the top of your head it'd be nice.

Can I ask a MUOS-5 related question. So they are delaying 7 days. Does that mean they are stopping all work on MUOS-5 for a week and looking at the data instead?

I assume if they find something in the data that needs correcting, this launch could slip more than 7 days. True? This is a penciled in date until they know the scale of a potential problem?

Processing continues. The Centaur just underwent first power application this week, and offsite vertical integration of up-stage components has started and will continue. Slipping the ILC just adds some pad to the integration/test schedule.

Sure, there's potential for further slippage, based on the pace of the investigation. Progress is being made, however.

Correct me if I'm wrong, but as I understand it they are going to delay the Atlas CCB move from the ASOC to the SLC-41 VIF by a day or so to do some checks that they cant easily do in the VIF while stacked on the MLP.

Cape Canaveral Air Force Station, Fla. (April 8, 2016) -- The Atlas V MUOS-5 launch is delayed and indefinite on the Eastern Range due to ongoing evaluation of the first stage  anomaly experienced during the OA-6 mission. ULA successfully delivered the OA-6 Cygnus spacecraft to the International Space Station (ISS) on March 22. The MUOS-5 spacecraft and launch vehicle are secure at their processing facilities.

Can the Delta-IV or Delta-IV heavy deliver MUOS-5 to the ego transfer orbit required?

Post by: MKremer on 04/09/2016 09:59 AM
Can the Delta-IV or Delta-IV heavy deliver MUOS-5 to the ego transfer orbit required?
One of them could, but they'd be looking at significant lead time to get something built and ready to launch. There's a good chance the time period would be over and above the time it takes to resolve the A-V problem. (That's assuming politics, from different sources, doesn't delay things even longer.)  If the decision is made, then, first, all of the payload and launch calculations and planning would have to be re-done, evaluated, and approved before any hardware starts getting assembled.

Regardless of multiple launch options and the commonality of interfaces for payloads, EELV isn't 'plug-n-play'. They don't have multiple boosters and 2nd stages sitting in storage waiting for payloads, either, especially for massive payloads like MUOS (almost 7.5t/6800kg). So the hardware will need time to be manufactured and assembled, and tested.

So there's that lead time, plus the launch operations once the hardware is ready, which can take an additional 2-3 months for the D-IV/D-IVH. So, maybe 10-12 months as a rough estimate (and that's probably an accelerated time table.)

Can the Delta-IV or Delta-IV heavy deliver MUOS-5 to the ego transfer orbit required?
Only the Heavy
It seems like the biggest Delta-IV could get pretty close to the desired orbit, maybe close enough in practice.  MUOS is quoted as massing 6740 kg, and the Atlas 551 puts it into a 3463xGEO at 19 degree orbit.  If I did the math right, that about 1425 m/s remaining. 

Delta-IV M+(5,4) is quoted as lifting 7430 kg to GEO-1800 orbit.  So if it lifted MUOS into this orbit, it would have about 700 kg of fuel left over.  Assuming a 2t Centaur, a 6.7t MUOS, and ISP of 450, the last 700kg of fuel should be good for an additional 340 m/s or so.  If you burned this at apogee, you have about 1470 m/s the satellite must supply.

Considering that GEO station-keeping costs something like 50 m/s per year, that implies only a 1 year reduction in lifetime compared to the Atlas launch.  For the savings in cost over a Delta-IV heavy this might be acceptable.

Of course this is just back of the envelope, and you'd need to worry about the mass of the adapter (is it included?), the mass of the kit to burn at apogee, disposal of the stage, etc.  But it might just barely be possible (though doubtless the Atlas is more desirable).

That isn't the desired orbit and hence that is why it is not able to launch MUOS. It doesn't matter Delta-IV M+(5,4) can get it to GEO-1800 orbit.  And it is more than just 1 year of spacecraft propellant.  There are also some fairing considerations.

Given the lead time on RS-68A and other long lead time items, a Delta IV Heavy needs no less than 30 month from ATP to launch. So say three years delay for switching to Delta IV. I guess they will wait to resolve the Atlas V anomaly.

Centennial, Colo., (April 29, 2016) --

Last Friday, in preparation for the MUOS-5 launch, the Atlas V completed the Launch Vehicle on Stand (LVOS) operation, erecting the Atlas V into the Vertical Integration Facility at Cape Canaveral Air Force Station. LVOS will allow configuration of the vehicle to support RD-180 engine inspections and confirm all engine components are ready for launch. The Atlas V MUOS-5 launch is targeted for early summer; a new launch date has not been secured on the Eastern Range. The impact to the remainder of the Atlas V manifest is in review with new launch dates being coordinated with our customers. All missions manifested for 2016 are expected to be successfully executed by the end of the year, including OSIRIS-REx, which will remain in early September to support its critical science window.

Ready to Go: Lockheed Martin-Built MUOS-5 Secure Communications Satellite Encapsulated for June 24 Launch

Date(s): 14-Jun-2016 11:36 AM

MUOS-5 Completes Constellation for U.S. Navy's New Network 

CAPE CANAVERAL AIR FORCE STATION, Fla.,  June 14, 2016  /PRNewswire/ -- The fifth Mobile User Objective System (MUOS) satellite built by  Lockheed Martin  (NYSE: LMT) for the  U.S. Navy  was encapsulated in its protective launch vehicle fairing on  June 4 . It is scheduled to launch  June 24  aboard a  United Launch Alliance Atlas V rocket.

MUOS-5 is the latest addition to a network of orbiting satellites and relay ground stations that is revolutionizing secure communications for mobile military forces. Users with MUOS terminals will be able to seamlessly connect beyond line-of-sight around the world and into the Global Information Grid. MUOS' capabilities include simultaneous, crystal-clear voice, video and mission data over a secure high-speed Internet Protocol-based system.

"Like its predecessors, MUOS-5 has two payloads to support both these new Wideband Code Division Multiple Access (WCDMA) waveform capabilities, as well as the legacy Ultra High Frequency (UHF) satellite system, used by many mobile forces today," said  Mark Woempner , program director of  Lockheed Martin's   Narrowband Communications  mission area. "On orbit, MUOS-5 will augment the constellation as a WCDMA spare, while actively supporting the legacy UHF system."

The MUOS-5 satellite joins four MUOS satellites already on orbit and four operational ground stations, providing near-global coverage including communications deep into polar regions. More than 55,000 currently fielded radio terminals can be upgraded to be MUOS-compatible, with many of them requiring just a software upgrade.

Once fully operational, MUOS will provide users with 16 times more communications capacity than the legacy system it will eventually replace. 

 Lockheed Martin  manufactured MUOS-5 at its  Sunnyvale, California  facility. In March, the satellite shipped to the Cape, where it was pre-launch processed and finally encapsulated at Astrotech Space Operations, a wholly owned subsidiary of  Lockheed Martin .

The  Navy's   Program Executive Office for Space Systems  and its Communications Satellite Program Office,  San Diego, California , are responsible for the MUOS program.

The first stage of the Atlas V is always orange-coppery. It's the colour of the insulation, because the tanks hold very cold liquid oxygen.

RELEASE #062416

45th SW supports successful Atlas V MUOS-5 launch

By 45th Space Wing Public Affairs

CAPE CANAVERAL AIR FORCE STATION, Fla. – The Air Force’s 45th Space Wing supported United Launch Alliance’s successful launch of the MUOS-5 spacecraft aboard an Atlas V rocket from Space Launch Complex 41 here June 24, 2016, at 10:30 a.m. ET.

The ULA Atlas V rocket is carrying the U.S. Navy's fifth Mobile User Objective System satellite built by Lockheed Martin. MUOS is the U.S. military’s answer to secure and reliable tactical communications. This next generation narrowband satellite communications system will provide significantly improved and assured communications for mobile warfighters.

“Today’s successful launch is the culmination of the 45th Space Wing, Space and Missile Systems Center, Navy and ULA’s close partnership and dedicated teamwork,” said Brig. Gen. Wayne Monteith, 45th Space Wing commander and mission Launch Decision Authority. “We continue our unwavering focus on mission success and guaranteeing assured access to space for our nation, while showcasing why the 45th Space Wing is the ‘World's Premiere Gateway to Space.’”

Atlas burns to depletion so no worries about a long burn there.  I guess a really long burn could mean an underperforming powerhead on the engine and thereby gravity losses, but <5s is attributable to other variables.

United Launch Alliance Successfully Launches MUOS-5 Satellite for the U.S Air Force and U.S. Navy
MUOS-5 completes the five-satellite constellation and acts as an on-orbit spare

Cape Canaveral Air Force Station, Fla., (June 24, 2016) – A United Launch Alliance (ULA) Atlas V rocket successfully launched the MUOS-5 satellite for the U.S. Navy. The rocket lifted off from Space Launch Complex-41 June 24 at 10:30 a.m. EDT.

MUOS-5 is the final satellite in the five-satellite constellation, which provides warfighters with significantly improved and assured communications worldwide.

“We are honored to deliver the final satellite in the MUOS constellation for the U.S. Navy,” said Laura Maginnis, ULA vice president, Custom Services. “Congratulations to our navy, air force and Lockheed Martin mission partners on yet another successful launch that provides our warfighters with enhanced communications capabilities to safely and effectively conduct their missions around the globe.”

       The mission was ULA’s fifth launch in 2016 and 108th launch since the company formed in 2006. MUOS-5 was the seventh mission to be launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 551 configuration vehicle, which includes a 5-meter diameter payload fairing and five solid rocket boosters. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.

            “I am so proud of the team for all their hard work and commitment to 100 percent mission success,” Maginnis said. “It is amazing to deliver our second national security payload from the Cape in just two weeks. I know this success is due to our amazing people who make the remarkable look routine.”

         ULA's next launch is the Atlas V NROL-61 mission for the National Reconnaissance Office, scheduled for July 28 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida.

        The EELV program was established by the U.S. Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.

With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered more than 100 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.

1.  I got about 4:30 from the launch replay video--ignition at 0:56, cutoff at 5:26 (not totally accurate due to commentator delay.)  The launch aritcle lists the burn as 4:25.6.

Atlas burns to depletion so no worries about a long burn there.  I guess a really long burn could mean an underperforming powerhead on the engine and thereby gravity losses, but <5s is attributable to other variables.

The burn duration was < 0.25 sec of pre-flight prediction.  As I mentioned in a previous post (in some other thread I can't find), the duration itself doesn't reveal much about performance.  You could have high thrust and high flowrates (nominal ISP), resulting in an earlier BECO, or you could have nominal thrust and high flow rates (lower ISP), resulting in an earlier BECO.  One good, one bad.
A 3-sigma high or low propellant load can also affect BECO time, as the stage burns to depletion.  Really have to see the state vector at BECO.

SAN DIEGO (NNS) -- The fifth Mobile User Objective System satellite, which successfully launched aboard a United Launch Alliance Atlas 5 on June 24, was projected to reach its geosynchronous orbit and enter its test location 22,000 miles above Hawaii by July 3.

The satellite experienced an anomaly that required the transfer maneuver to be temporarily halted.

The Navy's Program Executive Office for Space Systems has reconfigured the satellite from orbital transfer into a stabilized, safe intermediate orbit to allow the MUOS team to evaluate the situation and determine options for proceeding.

MUOS-5 was launched as an on-orbit spare to provide immediate redundancy to the MUOS constellation, which is performing nominally. MUOS-5 is an on-orbit spare, and delay in reaching its test location will have no impact upon current legacy or Wideband Code Division Multiple Access satellite communications operations.

MUOS-1 through MUOS-4 are now in orbit and supporting operations via their legacy payloads that provide ultra high frequency satellite communications for the Department of Defense.

The Navy's Program Executive Office for Space Systems, located at the Space and Naval Warfare Systems Command in San Diego, is responsible for the MUOS program.

The white orbit is the ~15250 x 35700 km, 9.8 degree inclined GTO orbit in which Paul Camilleri and me have observed the satellite over the period July 3-9. i.e. this is the orbit it is currently stranded in.

The red orbit is the initial insertion orbit from June 24. The grey orbit is the sunsynchronous geosynchronous (sorry, I was tired...) orbit it was aimed for.

Unlikely, though anomalies on govt satellites are classified. Still I don't see much overlap between the repaired item and the propulsion system.

The soldering issue was discovered last spring during thermal vacuum testing on a component of the MUOS legacy UHF payload provided by Boeing Space and Intelligence Systems of El Segundo, Calif. Boeing, which built the Navy’s earlier-generation UHF Follow-On mobile communications satellites, is a subcontractor to Lockheed Martin on MUOS. - See more at: http://spacenews.com/39833bad-soldering-pushes-3rd-muos-satellite-toward-end-of-the-launch-queue/#sthash.AcQnqiBh.dpuf

Not always, they where pretty open after the fact about what happened to AEHF 1 (USA 214). If it is something related to the non-classified nature of the satellite. I think they will eventually release the cause with some level of detail.

There was also this from AmericaSpace:
Quote
In an unrelated, important military space development, AmericaSpace has also learned exclusively that the Navy/Lockheed Martin Mobile Objective User System MUOS-5 communications spacecraft has begun climbing, after earlier being stuck 12,000 miles below its intended geosynchronous orbit checkout location over the Pacific Ocean.

The problem, likely involving propulsion and possibly control as well, occurred when the 7-ton spacecraft was halfway up its planned nine-day transfer to geosynchronous orbit following launch from Cape Canaveral on an Atlas-V on June 24 (see AmericaSpace report June 25).

Navy spokesman Steve Davis at the Space and Naval Warfare Systems Command in San Diego said the Navy is not yet ready to release details on the problem.

Sources told AmericaSpace, however, that an initial maneuver this month was able to move the spacecraft 25 miles higher, brightening hopes that the $611 million satellite can be eventually elevated to geosynchronous orbit even if it has to inch its way up.
http://www.americaspace.com/?p=94629

I believe that was posted on July 27, but I'm not 100% sure. I'm not up on the satellite tracking so I'm not sure if that slight raise would be noticeable to amateur observers.

U.S. Navy narrows MUOS-5 problem to orbit raising propulsion system

Quote
But in an Aug. 2 statement, the Navy said the satellite “experienced a failure of the orbit raising propulsion system,” five days into a 10-day climb, halting the transfer maneuver that would push the satellite from its initial elliptical launch orbit to geosynchronous orbit.

As a result, the Navy is “considering alternate orbit adjustment options, calculating mission impact and investigating all options before proceeding,” said Steven Davis, a spokesman for Space and Naval Warfare Systems Command.

“The MUOS 5 satellite is currently stable, safe and under positive control,” he said.

But it appears the satellite has performed some orbit-raising in recent days, albeit tiny compared to large-scale maneuvers. The Navy has not confirmed any movements, but hobbyists keeping tabs on the stricken satellite have seen the tell-tale signs.

“When Scott Tilley observed MUOS 5 on July 21 near 11:00 UTC, it was still in the orbit in which it had been stranded by the propulsion system failure on June 29. When he next observed it, on July 30 at 10:00 UTC, it was nearly 17 minutes late relative the orbit it had been in on July 21. That is an indication that it made one or more maneuvers in the interim. The orbit change probably was not large. A precise determination is pending further observations,” said Ted Molczan, a respected satellite observer.

...

With the 100-pound-thrust main engine now out of commission, ground controllers will look to the satellite’s small thrusters for saving the mission.

The craft is equipped with 18 monopropellant hydrazine thrusters designed for attitude control — a dozen 0.2-pound thrusters and six 5-pound thrusters.

...

The situation is reminiscent of the Air Force’s first Advanced Extremely High Frequency satellite that experienced a main propulsion system failure after launch due to a clogged fuel line. It was able to achieve geosynchronous orbit using its xenon-fed electric thrusters with no reduction to mission life.

But the MUOS satellites do not have a xenon propulsion system, only hydrazine.

I think that A2100 RCS uses monopropellant hydrazine while the liquid apogee engine burns hydrazine and N2O4.  Something like this maybe.  https://www.google.com/patents/US7762498 

There's a chance they can reach GEO, but I suspect it will cost a lot of the operational life.  They need another 600-700 ish m/s delta/v, maybe more.  That's probably a big chunk of the planned station keeping delta-v budget.  This all assumes that the problem isn't pressurization, which could be common to both systems.

Also:

Is the main engine mono-propellant or bi-propellant? It's typical for ISP reason to use a bi-propellant engine for the GTO to GSO transfer. I believe AEHF-1 used a similar engine from IHI which was bi-propellant (Hydrazine and Nitrogen Tetroxide).

If that is the case, you not only take an ISP hit because of the smaller engines, but also don't get the bi-propellant ISP benefit and have the dead weight of the Nitrogen Tetroxide you can not use. They will have to lug the Nitrogen Tetroxide all the way up hill to GSO.

So the question now becomes how many years will getting to GSO take off the satellites life?

Question based on Ed's patent posting. It looks like the apogee engine is pump fed vs. pressure fed.

So this brings up a few questions:
-Could it be a failed pump
-Pump verses pressure fed in this case should lead to a significant ISP hit
-It looks like the pumps are electronically powered. Is that a first (for operational rocket engines)?
-Blown breaker in the pump controller? Or other electrical problem?

Not to be morbid, but on such a complex system the reason behind this could be very interesting.

Ironically, the patent touts the advantage of being able to test the pumps during payload integration...but there are plenty of other potential culprits too.

Would it be normal for a spacecraft to have a share hydrazine tank, and a smaller oxidiser tank solely for the biprop engine? Or is it  more likely to be two completely separate systems (different pressurisation requirements might point to this?)

Both AEHF and MUOS had orbit raising propulsion anomalies. And it was in 25% of the cases. I'm surprised because we don't usually see those propulsion failures on commercial satellites. Thus, I'm very surprised to see this level of problems on ultra expensive and ultra n-tuple checked programs. Is this just really bad luck on LM side?

To better understand why the satellite was struggling, the Joint Functional Component Command for Space at Vandenberg Air Force Base in California tasked the Geosynchronous Space Situational Awareness Program, or GSSAP, satellites for an image of MUOS-5. Satellite operators from Schriever Air Force Base in Colorado Springs, Colorado then used rendezvous and proximity maneuvers to get the once-classified vehicle into position to capture the best images of the Navy satellite, the Air Force said in a press release. - See more at: http://spacenews.com/air-force-sent-gssap-satellite-to-check-on-stalled-muos-5/#sthash.PiIyU1kX.dpuf (http://spacenews.com/air-force-sent-gssap-satellite-to-check-on-stalled-muos-5/#sthash.PiIyU1kX.dpuf)

‘Neighborhood Watch’ supports Navy operations

By Jennifer Thibault, 50th Space Wing Public Affairs / Published August 17, 2016
Geosynchronous Space Situational Awareness Program artist rendering. Air Force Space Command’s “Neighborhood Watch” Satellites, the Geosynchronous Space Situational Awareness Program, recently responded to the Navy’s request for help with a satellite of its own.

SCHRIEVER AIR FORCE BASE, Colo. - Air Force Space Command’s “Neighborhood Watch” Satellites, the Geosynchronous Space Situational Awareness Program, recently responded to the Navy’s request for help with a satellite of its own.

The Joint Functional Component Command for Space officially tasked the 1st Space Operations Squadron to support Navy’s ongoing Mobile User Objective System-5 anomaly effort after the satellite failed to reach its target geosynchronous orbit on July 3.

Anomaly resolution in space is challenging for many reasons, one being it’s difficult to see what’s going on with the satellite.  Traditionally, engineers, analysts and operators comb through telemetry to come up with possible reasons for the anomaly, however in cases like this GSSAP is able to provide Electro Optical Space Situational Awareness on the status of space objects to include location, orbit and size of the space object.

GSSAP crews conduct Rendezvous and Proximity Operations to get the best possible vantage point for collecting SSA data when requested.  In this case, the mission was to help rescue MUOS-5.

Once tasked, 1 SOPS mission planning cell began the deliberate, customized mission planning to determine how to execute the operation and maximize the probability for success.  The satellites’ differing orbits and the various forces at play, including astrodynamics, reminded crewmembers that success was not inevitable.

Capt. Barbara Dyer, 1 SOPS mission commander, led the crew that accomplished the command and control operations to collect MUOS-5 imagery on her 10th shift.

“I knew we were prepared.  We had completed the rehearsal of concept for the unique mission,” she said.  “We recognized the newness of what we’re doing will drive new expectations.”

Second Lt. Nathan Paddock is the satellite vehicle operator who executed the C2 for the operations.

“There were a lot of different people on the operations floor during the shift,” he said.  “Senior leadership was there encouraging us and reminding us that this was something very important.  I am new to the Air Force and the job, but knowing leadership trusted me and expected excellence is something that’s unique to this work.”

The audience and mission importance added to the pressure to achieve success but that didn’t deter Paddock.

“I liked it.  I thrive under pressure,” he said.  “The crew engineers gave us a lot of support and helped me stay calm and relaxed.  I know they had my back.”

The crew conducted SSA missions with other 1 SOPS assets, like the Space Based Space Surveillance system, in preparing for and during the mission.

While planning and operations were conducted at Schriever, another aspect of this unique mission occurred at Point Mugu, California.

“Due to the complexity of the program we wanted someone on site to provide context to Navy leadership, explain our operations, facilitate information sharing and ensure there was robust coordination  during the operations,” said Lt Col Casey Beard, 1 SOPS commander.

The squadron’s mission planning cell chief, Capt. Brett Kasischke, was just up the road at Vandenberg AFB, California, to participate in an exercise.  He capitalized on the opportunity and extended his stay in California.

“I quickly immersed myself into the mission’s requirements  and served as an intermediary; I ensured data was sent at appropriate times as well as supported the team back at Schriever,” Kasischke said.

The mission’s full impact is yet to be determined, but there are successes already to be celebrated.

“I am proud of the team effort across the community,” said Beard. “From our crew here at Schriever to the Space and Missile System Center, the Joint Functional Component Command for Space, the Joint Space Operations Center, our  Navy counterparts at Point Magu and the contractors who dedicated 800 hours to mission planning, it was a true team effort and couldn’t have happened without everyone coming together.”

“The detailed planning was an outstanding learning event for our crews. Our tactics, techniques and procedures were refined and, when called upon to assist with another satellite anomaly, we will be ready.  We have more confidence in our teams and our training programs,” said Kasischke.  “The dynamic nature of the mission and complexity of operations, it’s what we’re here to do and it’s going to shape future operations.”

MUOS 5 is in an slightly inclined geostationary transfer orbit.

The 2 operational GSSAP satellites are in geosynchronous orbits.

My deduction: The GSSAP satellites were moved, and maybe their orbits temporarily inclined?, so that their geocentric longitude matched the apogee of MUOS 5.  This would allow documentation imagery.

If both GSSAP satellites were used, they could be spaced in geosynchronous orbit to match geocentric longitudes of successive MUOS 5 apogees.  MUOS 5 is currently completing about 1.5 orbital revolutions/day (from Heavens-above.com http://www.heavens-above.com/orbit.aspx?satid=41622&).

MUOS 5's relative velocity would be lowest at apogee (Kepler's laws), so that would make GSSAP imagery attempts easier?

This work may explain why MUOS 5's orbit hasn't changed much in recent days--to allow the imagery documentation.

Question for the amateur satellite observers: Are there any conjunctions of MUOS 5 and either of the operational GSSAPs?

Heavens-above.com has orbital elements for USA 253 as of October 9, 2015, and for USA 254 as of August 12, 2016. (GSSAP 1 & 2)

Applicable part of a post in the SBIRS GEO-3 thread copied over for reference...

Fueling of the satellite and the launch, originally scheduled for Oct. 3, was delayed on Sep. 10 by Lt Gen Samuel Greaves, SMC commander and Air Force Program Executive Officer for Space (PEO/Space) to give the SBIRS government/contractor engineering team time to investigate a potential parts issue discovered on two other non-SBIRS satellites. A preliminary review of the data suggested a possible issue with the liquid apogee engines. A Liquid Apogee Engine is used by the SBIRS satellite to provide the thrust required to raise the satellite to the proper orbit after the spacecraft has been released from the launch vehicle. Earlier this month, a non-Lockheed Martin commercial satellite experienced a similar anomaly to the July MUOS-5 event. The Air Force is working to understand the commonality between the two anomalous engines and the SBIRS design. The SBIRS satellite remains safe at the launch base.

To date, the joint government and industry team has reviewed approximately 90% of the design, build, and test data from the anomalies. Additionally, all design similarities between the SBIRS liquid apogee engines and the anomalous engines have been fully documented and are understood. The team expects to complete the investigation within the next couple of weeks.

I would assume they are using the maneuvering thrusters to raise its orbit then? What impact will this have on life expectancy given they are only mono propellant versus the main engine is bi-propellant. I would think this would exhaust a considerable amount of the fuel needed for station keeping.

Perhaps they plan to put it in service this way and later attempt to use it as an experiment for refueling?

I wouldn't be surprised if MUOS-5 is switched from Spare to Primary status since its life will now be shorter than the others.

Ted Molczan estimates the remaining propellant quantities aboard MUOS 5: http://www.satobs.org/seesat/Oct-2016/0139.html (http://www.satobs.org/seesat/Oct-2016/0139.html)

He considers it likely that MUOS 5 will stay at the Western stable libration point to minimize the need for station keeping maneuvers. He finds that in order to reach the current geosynchronous orbit at this libration point, the orbital inclination was not reduced to the typical 5 deg values, but instead was kept close to the 9.7 deg that the orbit was in after the liquid apogee engine failed.

From Space and Naval Warfare Systems Command Public Affairs

SAN DIEGO (NNS) -- The Navy's fifth Mobile User Objective System (MUOS) satellite has reached operational orbit and has successfully deployed its arrays and antennas.

On Oct. 22, the MUOS team raised the MUOS-5 satellite to an operationally-suitable orbit. The team completed a series of deployments of the satellite's solar arrays and antennas, with the last occurring successfully Oct. 30.

MUOS-5 launched June 24 from Cape Canaveral Air Force Station and experienced a failure of its orbit raising propulsion system that halted the satellite's transfer orbit maneuver to its geosynchronous test orbit. The MUOS team ensured the satellite remained stable, safe, and under positive control while it investigated the issue and examined options.

"We are very proud of the commitment our team members demonstrated," said Capt. Joe Kan, program manager for the Navy Communications Satellite Program Office. "Working together with industry, we were able to execute an alternative propulsion method to maneuver MUOS-5 to reach a position that is operationally suitable."

MUOS-5 is scheduled to begin on-orbit Nov. 3. It will complete the five-satellite MUOS constellation once on-orbit testing is complete.

"The system will undergo on-orbit testing before final acceptance of the system by the Navy and offering it up for operational use," said Cmdr. Jason Pratt, MUOS principal assistant program manager. "The satellite and its payloads will go through rigorous tests with our ground systems and terminals to make sure everything operates properly."

The MUOS system is designed to provide improved communications capabilities to users around the world, regardless of where they are in relation to a satellite. The MUOS constellation and associated ground network will provide 3G-like cellphone communications for the next decade and beyond.

The Navy's Program Executive Office for Space Systems, located at the Space and Naval Warfare Systems Command in San Diego, is responsible for the MUOS program.

MUOS-5 Secure Communications Satellite Reaches Orbit, Begins Pre-Operational Testing

4-Nov-2016 11:34 AM

SUNNYVALE, Calif. , Nov. 4, 2016 /PRNewswire/ -- The fifth Mobile User Objective System (MUOS) satellite built by Lockheed Martin (NYSE:LMT) for the U.S. Navy has reached orbit, successfully deployed its solar arrays and antennas, and is beginning pre-operational, on-orbit testing.

Originally launched from Cape Canaveral Air Force Station on June 24 , MUOS-5 experienced an anomaly with its orbit raising propulsion system on its way to geosynchronous orbit on June 29 . Out of caution, the Navy and Lockheed Martin engineering team immediately placed the satellite in a safe mode in transfer orbit as they investigated and examined their options.

"In the end, the Navy and Lockheed Martin engineering team were able to isolate the issue and develop a work-around using alternative propulsion," said Mark Woempner , director of Narrowband Communications Systems at Lockheed Martin . "Once we had a plan together, in early October we carefully re-started orbit raising maneuvers."

MUOS-5 completed orbit raising on Oct. 22 , and successfully deployed its solar arrays for power generation and its antennas for mission operations on Oct. 30 . The satellite will begin on-orbit testing before being turned over to the Navy for further testing and eventual commissioning into service.

For the Navy , MUOS-5 completes a network of orbiting satellites and relay ground stations that is revolutionizing secure communications for mobile military forces. Users with MUOS-capable terminals will be able to seamlessly connect beyond line-of-sight around the world and into the Global Information Grid, as well as into the Defense Switched Network. MUOS' capabilities include simultaneous, crystal-clear voice, video and mission data over a secure high-speed Internet Protocol-based system.

The MUOS network provides near-global coverage, including communications reach deep into polar regions. Once fully operational, the network will provide users with 16 times more communications capacity than the legacy system it will eventually replace.

The Navy's Program Executive Office for Space Systems and its Communications Satellite Program Office responsible for the MUOS program are based in San Diego . Lockheed Martin assembled and tested all five now-on-orbit MUOS satellites at its Sunnyvale, California , facility.

U.S. Navy's Fifth Lockheed Martin-Built MUOS Satellite Now Supporting Troops with Ultra High Frequency Communications

MUOS-5 Completes Global Military Cellular Network As Spare For Next-Generation Capabilities

SUNNYVALE, Calif., April 24, 2017 /PRNewswire/ -- The fifth Lockheed Martin (NYSE-LMT)-built Mobile User Objective System (MUOS-5) satellite is now delivering secure, beyond-line-of-sight communications to troops with legacy Ultra High Frequency (UHF) radios.

The U.S. Navy, working with Army Forces Strategic Command, configured one of MUOS-5's two communications payloads – its legacy UHF payload – to provide additional support for the Navy's legacy UHF satellite communications mission. Today, narrowband UHF communications is used by every Combatant Command in aircraft, ships, submarines, ground vehicles, as well as by troops in the field and special operations.

Eventually, legacy narrowband UHF communications will transition to next generation Wideband Code Division Multiple Access (WCDMA) capabilities provided by MUOS. To facilitate that transition, MUOS was intentionally designed with two communications payloads.

"Each MUOS satellite can simultaneously support both new WCDMA waveform capabilities and legacy UHF satellite communications," explained Mark Woempner, director of Narrowband Communications Systems at Lockheed Martin. "With MUOS 1-4 already on orbit providing near global WCDMA coverage, MUOS-5 will actively support legacy UHF communications and serve as an on-orbit WCDMA spare."

MUOS-5 is the latest edition to a network of orbiting satellites and relay ground stations that is revolutionizing communications for mobile forces. Users with new MUOS terminals will be able to seamlessly connect beyond line-of-sight around the world and into the Global Information Grid, as well as into the Defense Switched Network. MUOS' capabilities include simultaneous, crystal-clear voice, video and mission data over a secure high-speed Internet Protocol-based system.

More than 55,000 currently fielded radio terminals can be upgraded to be MUOS-compatible, with many of them requiring just a software upgrade.

Once fully operational, MUOS will provide users with more than 10 times the communications capacity of the legacy system it will replace. The network provides near-global coverage, including communications into polar regions. MUOS also has demonstrated successful communication of Integrated Broadcast Service (IBS) messages to in-flight test aircraft.

"The industry team for MUOS is an incredible partnership. Next for MUOS, we are laser-focused on bringing the complete system to full operational capability for the Navy," said Woempner. "Early combatant commander testing began in July 2016, and we have already received valuable user feedback and are working to rapidly incorporate their needs into the system."

MUOS-5 begins this transition after successful completing post-launch, on-orbit testing on January 19. The satellite completed orbit raising and successfully deployed its solar arrays and antennas for mission operations on Oct. 30, 2016.

Originally launched on June 24, 2016, MUOS-5 experienced an anomaly with its orbit raising propulsion system on its way to geosynchronous orbit. The Navy and Lockheed Martin engineering teams were able to isolate the issue and deliver MUOS to operational orbit using alternative propulsion.

The Navy's Program Executive Office for Space Systems and its Communications Satellite Program Office responsible for the MUOS program are based in San Diego, California. Lockheed Martin assembled and tested all five now-on-orbit MUOS satellites at its Sunnyvale, California, facility.

U.S. Navy Accepts Fifth Lockheed Martin-Built MUOS Satellite for New Secure Global Military Cellular Network

MUOS-5 Supports Legacy UHF Comms; Serves As Spare For New Capabilities

NAVAL BASE VENTURA COUNTY, POINT MUGU, Calif., Nov. 16, 2017 /PRNewswire/ -- The U.S. Navy's Communications Satellite Program Office, PMW 146, and Lockheed Martin (NYSE: LMT) handed over full operational control of the fifth Mobile User Objective System (MUOS) satellite to the Naval Satellite Operations Center (NAVSOC).

The October 11 milestone followed the successful completion of the MUOS-5 satellite's on-orbit testing and delivery of all operational products needed to "fly" the satellite. In April, the Navy, working with Army Forces Strategic Command (ARSTRAT), configured one of MUOS-5's two communications payloads – its legacy Ultra High Frequency (UHF) payload – for testing.

The handover of this satellite to NAVSOC clears the final hurdle allowing for ARSTRAT to provide the payload's final configurations to support the Navy's legacy UHF satellite communications mission.

"Today, every Combatant Command in aircraft, ships, submarines, ground vehicles, as well as by troops in the field and special operations, rely upon secure, beyond-line-of-sight UHF satellite communications provided by the Navy," said Mark Woempner, Lockheed Martin's director for Narrowband Communications. "ARSTRAT's final configuration of MUOS-5's UHF legacy payload allows the satellite to fully support our military forces in these Combatant Commands."

Eventually, legacy narrowband UHF communications will transition to next generation Wideband Code Division Multiple Access (WCDMA) capabilities. To facilitate that transition, all five on-orbit MUOS satellites were intentionally designed with two communications payloads to support both Legacy UHF and WCDMA.

Early combatant commander testing of the on-orbit WCDMA payloads began in July 2016. The new MUOS capabilities will revolutionize communications for mobile forces with simultaneous, crystal-clear voice, video and mission data over a secure high-speed Internet Protocol-based system. Users with new MUOS terminals will be able to seamlessly connect beyond line-of-sight around the world and into the Global Information Grid, as well as into the Defense Switched Network, as part of the Navy's worldwide cellular network.

Once fully operational, the MUOS network of five on-orbit satellites and four relay ground stations will provide more than 10 times the communications capacity of the legacy UHF satellite system. MUOS' network already provides near-global coverage, including communications into polar regions. MUOS also has demonstrated successful communication of Integrated Broadcast Service (IBS) messages.

"We continue to receive great and constructive feedback on MUOS' capabilities as more users try it out. Similar to a civilian cellular phone service, upgrades to this new secure global military cellular network are ground-based and designed in an AGILE software development environment. We continue to make upgrades to the system based on user needs and look forward to bringing its full capabilities to our warfighters," Woempner said.

Today there are more than 55,000 radio terminals currently fielded that can be upgraded to be MUOS-compatible, with many of them requiring just a software upgrade.

The Navy's Program Executive Office for Space Systems and its Communications Satellite Program Office responsible for the MUOS program are based in San Diego, California. Lockheed Martin assembled and tested all five now-on-orbit MUOS satellites at its Sunnyvale, California, facility.
