Atlas V 551 - AFSPC-11 - April 14, 2018
« on: 01/20/2018 10:35 AM »
Seeing that launch is coming up and no topic exists yet for this one, here's one.  ;)

So does anyone have ideas of what AFSPC-11 is? I was initially surprised by the use of the -551, but according to Gunther the EAGLE spacecraft will be on board and to be flown directly to geostationary orbit. That spacecraft "...can support payloads up to a weight of 1086 kg for a mission of at least one year." so it could be weighting up to 2 tonnes, which is already about half of the maximum capability of the -551 (just shy of 4 tonnes to GEO).

So another "satellite surveillance/inspector" thingy? What other kinds of satellites would the AFSPC potentially operate?

With the Atlas V-551 the MUOS satellites were placed in the GEO orbit, which had a mass of ~ 6740 kg!

You are right, not directly in GEO.

Payloads flying on AFSPC-11:
Primary Payload AFSPC-11 is completely classified at this time.
Secondary Rideshare is EAGLE (carrying payloads: HTI-SpX, MYCROFT (Classified), CEASE-III-RR, ISAL, ARMOR).

Public information:
http://space.skyrocket.de/doc_sdat/eagle.htm
http://space.skyrocket.de/doc_sdat/mycroft.htm

ISAL is satellite surveillance/inspector" thingy that you are looking for. ISAL (Inverse Synthetic Aperture Ladar) to provide high resolution images which are not limited in resolution by the diffraction limit of the telescope collecting the imaging data. This makes it an ideal method for imaging Geosynchronous Earth Orbit (GEO) space objects which happens to be ISAL's primary mission.

Spacecraft/Payload Acronyms:
EAGLE (ESPA Augmented Geostationary Laboratory Experiment) (Built using OATK ESPAStar Platform
HTI-SpX (Hypertemporal Imaging Space Experiment)
MYCROFT (Acronym is classified. Built using OATK ESPASat Bus.)
CEASE-III-RR (Compact Environmental Anomaly Sensor III Risk Reduction)
ISAL (Inverse Synthetic Aperture Ladar)
ARMOR (AFRL - 1201 Resilient Spacecraft Bus Development Experiment)

Inverse synthetic aperture LADAR for geosynchronous space objects – signal-to-noise analysis
Pellizzari, Matson, and Gudimetla
September 2011
http://www.dtic.mil/docs/citations/ADA550680
http://www.dtic.mil/dtic/tr/fulltext/u2/a550680.pdf

Inverse synthetic aperture LADAR (ISAL) provides high resolution images which are not limited in resolution by
the diffraction limit of the telescope collecting the imaging data. This makes it an ideal method for imaging
Geosynchronous Earth Orbit (GEO) space objects. Although LADAR is a well researched topic, little has been
published on the suitability of ISAL for imaging GEO space objects and the associated SNR models. This paper
derives an expression for the return signal detected by a coherent ISAL system. Using tomographic techniques
common to synthetic aperture radar (SAR), a model is developed for the signal-to-noise ratio of the reconstructed
image. Noise sources considered include photon noise and laser speckle noise.

ISAL is one of the experiments that will form the basis for missions such as for example GSSAP Follow On, which, is soon to enter the formulation stage by USAF and other government agency partners, might use technology derived from ISAL and other flown and upcoming STP experiments. ISAL also has  a air based hyperspectral equivalent that is used by the Civil Air Patrol (USAF AUX) and other agencies called Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance (ARCHER) that is currently in use for Search and Rescue and other classified sorties.

LOS ANGELES AIR FORCE BASE, Calif. --

CAPE CANAVERAL AIR FORCE STATION, Fla. -- The Continuous Broadcast Augmenting SATCOM, or CBAS, Satellite completed launch base testing March 15 in preparation for the payload’s scheduled launch aboard the AFSPC-11 mission.

The U.S. Air Force is scheduled to launch the CBAS satellite and the Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) Augmented Geosynchronous Laboratory Experiment (EAGLE) satellite on the AFSPC-11 mission aboard a United Launch Alliance Atlas V EELV from Space Launch Complex 41, Cape Canaveral Air Force Station, Florida, in mid-April.

 Managed by the Military Satellite Communications Directorate of the U.S. Air Force’s Space and Missile Systems Center, the CBAS Satellite is a military satellite communications spacecraft destined for geosynchronous orbit to provide communications relay capabilities to support our senior leaders and combatant commanders.  The mission of CBAS is to augment existing military satellite communications capabilities and broadcast military data continuously through space-based, satellite communications relay links.

 The Air Force Space Command's Space and Missile Systems Center, located at the Los Angeles Air Force Base, Calif., is the U.S. Air Force's center of excellence for acquiring and developing military space systems.  Its portfolio includes the Global Positioning System, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control networks, space based infrared systems, and space situational awareness capabilities.

Overview says deploy orbit is  circular  equatorial with 24498 naut mi semi major axis. This corresponds to
altitude of 38992 km, 3200 km above GEO. That's rather odd.

Probably.

So what do we think the mass of CBAS is? ULA says Atlas 551 carries 3850 kg
to GEO.  Eagle is probably at least 500 kg, and MYCROFT about 100 kg.
So CBAS is at most 3200 kg or so.

Who built it? Orbital? Boeing? Loral?

We also don't know much about the subsatellite MYCROFT. The upper case name implies it's
an acronym. Seems likely that the OFT is Orbital Flight Test.  Anyone want to guess the MYCR? :-)

Some helpful info:
EAGLE:
ESPAStar Platform dry mass according to OATK is 1086 kg Payload (181 kg per Port).

MYCROFT:
ESPASat Bus is 70kg nominal dry mass with 30kg payload capability.

it is a classified government payload that based on lessons learned from ANGELS. Also note that all other secondary payloads aboard EAGLE are testing additional improvements to the GSSAP mission in addition to other experiments.

I think that's a typo.

Geosynchronous is 42,164.2 km semi major axis, which is 22,766.8 nmi (or 26,199.6 mi), while the given number is 24,498.1 nmi. That's a pretty big typo! Orbital period is 26.72 hours compared to 23.93 hours for GEO.

Probably 22,498 for delivery into a drift orbit.

Probably 22,498 for delivery into a drift orbit.

We have the time from first ignition to apogee is T=18,708.8 seconds (5h11m18.8s). We have the time from perigee to apogee as, where sma is the semi major axis and mu is Earth's constant

T = pi*sqrt(smał/mu)

This gives sma = 24,179 km. Assuming hp=185 km and

sma = R+(hp+ha)/2

where R is the Earth's radius and ha is apogee, we have the apogee as ha = 35,417 km, close to geosynchronous! So it definitely is a typo. :-) Circular sma = 22,498 nmi is 35,288 km altitude.

The geostationary circularization burn will happen over Asia and Australia. Unfortunately this happens during daytime so the burn and fuel dump will likely go unnoticed.

OK - I am told apparently it is not an acronym and - I would argue - should not have been in upper case.

A small Hint: OATK and USAF list MYCROFT as Mycroft unlike ANGELS which is upper case because every letter stands for something. You are analyzing it wrong.

The third cutoff should be about now. The payloads are expected to be deployed within the next one hour and 20 minutes, with the window ending at 6:10 UTC. We'll now have to wait on ULA or Tory Bruno to announce whether the mission was a success or not.

(Cape Canaveral Air Force Station, Fla., April 15, 2018) A ULA Atlas V rocket carrying the AFSPC-11 mission for the U.S. Air Force lifts off from Space Launch Complex-41 at 7:13 p.m. ET on April 14.

 United Launch Alliance Successfully Launches AFSPC-11 Mission
for the U.S. Air Force

Cape Canaveral Air Force Station, Fla., (April 15, 2018) – A United Launch Alliance (ULA) Atlas V rocket carrying the Air Force Space Command (AFSPC)-11 mission lifted off from Space Launch Complex-41 on April 14 at 7:13 p.m. EDT. AFSPC-11 is a multi-payload mission. The forward payload is referred to as CBAS (Continuous Broadcast Augmenting SATCOM) and the aft spacecraft is EAGLE (EELV Secondary Payload Adapter (ESPA) Augmented Geosynchronous Experiment).

“Today’s launch is a testament to why the ULA team continually serves as our nation’s most reliable and successful launch provider for our nation’s most critical space assets,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “I want to thank the entire ULA team, and the phenomenal teamwork of our mission partners.”

This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 551 configuration vehicle, which includes a 5-meter large Payload Fairing (PLF). The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine. Aerojet Rocketdyne provided the five AJ-60A solid rocket boosters (SRBs) and RL10C-1 engine for the Centaur upper stage.

 

This is the 77th launch of the Atlas V rocket, ULA’s 4th launch in 2018 and the 127th successful launch since the company was formed in December 2006.

ULA's next launch is the InSight mission for NASA on an Atlas V rocket. The launch is scheduled for May 5 at Space Launch Complex-3 at Vandenberg Air Force Base, California.

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 125 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.

Congats to the Atlas team.

I think the fifth photo in this sequence has to be one of the best launch photos I've ever seen since 1957 !

Only  a Saturn V pad liftoff matches it for showing the " raw beauty and power" of a rocket liftoff

United Launch Alliance Successfully Launches AFSPC-11 Mission for the U.S. Air Force

Cape Canaveral Air Force Station, Fla., (April 15, 2018)
– A United Launch Alliance (ULA) Atlas V rocket carrying the Air Force Space Command (AFSPC)-11 mission lifted off from Space Launch Complex-41 on April 14 at 7:13 p.m. EDT. AFSPC-11 is a multi-payload mission. The forward payload is referred to as CBAS (Continuous Broadcast Augmenting SATCOM) and the aft spacecraft is EAGLE (EELV Secondary Payload Adapter (ESPA) Augmented Geosynchronous Experiment).

“Today’s launch is a testament to why the ULA team continually serves as our nation’s most reliable and successful launch provider for our nation’s most critical space assets,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “I want to thank the entire ULA team, and the phenomenal teamwork of our mission partners.”

This mission was launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 551 configuration vehicle, which includes a 5-meter large Payload Fairing (PLF). The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine. Aerojet Rocketdyne provided the five AJ-60A solid rocket boosters (SRBs) and RL10C-1 engine for the Centaur upper stage.
 
This is the 77th launch of the Atlas V rocket, ULA’s 4th launch in 2018 and the 127th successful launch since the company was formed in December 2006.
ULA's next launch is the InSight mission for NASA on an Atlas V rocket. The launch is scheduled for May 5 at Space Launch Complex-3 at Vandenberg Air Force Base, California.

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 125 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.

Four objects catalogued, payloads named USA 283 and USA 284, the Centaur and a piece of Centaur debris.  No orbital data, presumably classified, we'll have to wait for the hobbyists to do their stuff.

Is that from knowledge, or just guess? It's not clear to me that Mycroft necessarily separates from EAGLE right away. We could end up with debris plus a later object E as Mycroft.

But perhaps you have inside knowledge of a successful Mycroft deploy.

If i got the webcast right, Mycroft is for early orbit self inspection - so it would make sense to deploy it early in the mission.

Orbital ATK-Designed Satellites Demonstrate Affordable Access to Space for U.S. Air Force

Company’s ESPAStar and ESPASat Platforms Deliver Advanced Capabilities for Multiple Payload Missions

Dulles, Virginia 15 April 2018 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, designed the EAGLE (ESPA Augmented Geostationary Laboratory Experiment) experimental satellite for the U.S. Air Force’s AFSPC-11 mission that successfully launched  on United Launch Alliance’s Atlas V vehicle April 14 from Cape Canaveral Air Force Station, Florida. The AFSCPC-11 mission included a second company designed satellite, Mycroft, which is among several Department of Defense experiments hosted on the EAGLE platform as separate payloads.

The EAGLE and Mycroft satellites are based on the company’s ESPAStar™ and ESPASat™ products, which provide modular, cost-effective and highly capable infrastructure resources for hosting technology development and operational payloads. The Orbital ATK-designed EAGLE satellite is the first spacecraft based on the company’s innovative ESPAStar platform. The ESPAStar vehicle can accommodate any combination of up to six hosted or 12 separable, free-flyer payloads in low and geosynchronous orbit and is built to provide an even greater level of access to space. Orbital ATK designed and delivered the EAGLE satellite under a contract with the U.S. Air Force Research Laboratory (AFRL) Space Vehicles Directorate.

After a successful separation from the launch vehicle, EAGLE is hosting several Department of Defense payloads, including Mycroft, the second Orbital ATK-designed satellite to be deployed on the mission. Mycroft, a separable, fly-away experiment, utilized the company’s ESPASat platform for its flight. ESPASat is designed as an affordable GEO bus that can be launched as a secondary payload from an ESPAStar platform.

“Orbital ATK is proud to partner with the U.S. Air Force on the EAGLE and Mycroft missions,” said Chris Long, Vice President, National Security Systems at Orbital ATK. “Our unique capabilities to host separating and non-separating payloads represent a turning point in affordable access to space for small satellites and payloads.”

In addition to work performed at the company’s facility in Dulles, Virginia, Orbital ATK sites in Commerce, California, and Beltsville, Maryland, provided tanks and heat pipes to the EAGLE and Mycroft satellites.

45th SW supports successful Atlas V launch of AFSPC-11 mission

By 45th Space Wing Public Affairs

CAPE CANAVERAL AIR FORCE STATION, Fla. – The U.S. Air Force’s 45th Space Wing supported United Launch Alliance’s successful launch of the AFSPC-11 spacecraft aboard an Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station Apr. 14 at 7:14 p.m. ET.

Today’s successful launch of AFSPC-11 enables the opportunity for increased satellite communications capabilities for the warfighter once its payload reaches geosynchronous orbit. The AFSPC-11 mission consists of the Continuous Broadcast Augmenting SATCOM (CBAS) forward payload and the EELV Secondary Payload Adapter (ESPA) Augmented Geosynchronous Laboratory Experiment (EAGLE) aft payload.

"The experiments and data collected will pay dividends to the future of space exploration and our knowledge of space capabilities, which directly supports the warfighter,” said Brig. Gen. Wayne Monteith, 45th Space Wing commander and mission Launch Decision Authority. “We could not do this without the expertise and continued awareness from our partners who work hard daily to put the space domain first. Congratulations to Space and Missile Systems Center, Air Force Research Laboratory, and United Launch Alliance on another successful launch!"

The AFSPC-11 mission also marks two of three launches this month supported by the 45th Space Wing this month alone launches this month and well on our way to the Drive to 48.

I think that's a typo.

Geosynchronous is 42,164.2 km semi major axis, which is 22,766.8 nmi (or 26,199.6 mi), while the given number is 24,498.1 nmi. That's a pretty big typo! Orbital period is 26.72 hours compared to 23.93 hours for GEO.
Probably 22,498 for delivery into a drift orbit.
Looks very like this from detection by Brad Young.

ESPASat SC bus can also deploy secondary payloads from itself.

Unless ARMOR (AFRL - 1201 Resilient Spacecraft Bus Development Experiment) was actually deployed and the payload information about it being fixed was an error otherwise their was an unannounced payload. The EAGLE graphics for the launch show 2 deployable sats.

EAGLE could carry six payloads, but only five were announced. Perhaps a sixth highly classified payload was carried as well, but was not announced due to its classified nature.

A third subpayload has now been cataloged! So we have CBAS, Eagle, Centaur, debris and three small payloads

So with the SeeSat observation of the Centaur in a 32000 x 35344 km orbit after disposal,
I assume we conclude the 38992 km deployment orbit in the ULA press kit was just bogus?
