1st Boeing-built Inmarsat-5 Satellite on Track for 2013 Launch
High-data-rate communications satellite passes key environmental test
EL SEGUNDO, Calif., Sept. 17, 2013 -- The first of three Inmarsat-5 Global Xpress (GX) satellites being built by Boeing [NYSE: BA] has successfully completed a key system life test, paving the way for it to launch later this year. The satellite performed as expected during the spacecraft thermal vacuum test, which simulated the cold, airless vacuum of space.
"We remain focused on continuing to complete crucial milestones to successfully deliver this series of satellites," said Craig Cooning, vice president and general manager of Boeing Space & Intelligence Systems. "The Inmarsat-5 series is built on our 702HP model of satellites, which is flight-proven with over 20 spacecraft in orbit."
When operational, the Inmarsat-5 satellites will support Inmarsat's Global Xpress network, the world's first high speed, mobile broadband service, providing vital data connectivity for government and commercial users on land, at sea and in the air. The two remaining satellites, which will complete Global Xpress' global coverage, are currently in production at Boeing's Satellite Development Center.

Inmarsat-5 F1, 2, 3
Inmarsat ordered three Ka-band Inmarsat-5 satellites in August 2010 from Boeing for about $1 billion to deliver faster broadband to its commercial and government customers by end-2014.
The fixed-price contract, with options, calls for three BSS-702HP commercial spacecraft that will operate in geosynchronous orbit with flexible global coverage.
Each Inmarsat-5 satellite will carry 89 Ka-band beams that will operate in geosynchronous orbit with flexible global coverage. The satellites are designed to generate approximately 15 kilowatts of power at the start of service and approximately 13.8 kilowatts at the end of their 15-year design life. To generate such high power, each spacecraft's two solar wings employ five panels each of ultra triple-junction gallium arsenide solar cells. The BSS-702HP carries the xenon ion propulsion system (XIPS) for all on-orbit maneuvering. When operational, the Inmarsat-5 satellites will provide Inmarsat with a comprehensive range of global mobile satellite services, including mobile broadband communications for deep-sea vessels, in-flight connectivity for airline passengers and streaming high-resolution video, voice and data.
The Boeing satellites will provide Inmarsat with the ability to adapt to shifting subscriber usage patterns of high data rates, specialized applications and evolving demographics over a projected 15-year lifetime. In a separate arrangement, Boeing has also entered into a distribution partnership with Inmarsat to provide L- and Ka-band capacity to key users within the U.S. government.
The Inmarsat-5 spacecraft will be compatible with the Ariane, Sea Launch, Proton and Atlas launch vehicles. Launch services will be procured by Inmarsat.

Breeze M Delivered to Baikonur For Inmarsat 5F-1 Satellite Launch
The Breeze M upper stage designated to the Proton launch vehicle that will be used to loft Inmarsat 5F-1 for Inmarsat (Great Britain) was delivered today to Baikonur Launch Base.
The Breeze M upper stage was brought to Baikonur’s Yubileyny Airfield aboard an Antonov cargo plane operated by Polet. The plane landed at approximately 10:00 a.m. Moscow Time.
Today the Breese M will be moved to Integration-and-Test Facility 92A-50 where the Proton M launch vehicle meant to put Inmarsat 5F-1 into orbit and the satellite currently are being processed according to schedule.
The Proton M/Breeze M launch services for the Inmarsat 5F-1 mission were contracted by International Launch Services Inc. (ILS), a Russia-U.S. joint venture. The Inmarsat 5 F-1 launch mass is approximately 6.0 tons. The satellite was built by Boeing Satellite Systems.
The Inmarsat 5 F-1 launch is scheduled for December 2013.

SC ARRIVAL!
November 11, 2013 12:00 am (GMT)
ILS Launch Team
With the full Inmarsat-5 F1 team gathered in Baikonur, they headed to Yubileiny Airfield to meet the Antonov-124 that was delivering the Inmarsat-5 F1 spacecraft. Just like commercial flights, the Antonov-124 can also experience weather delays, as was the case today due to rough weather over Canada and Iceland. After touchdown the SC in its container was slowly and precisely maneuvered to the railcar for its journey to hall 92A-50 and arrived at approximately 00h30 on 12 Nov.

SC OFFLOAD AND FITCHECK
November 12, 2013 12:00 am (GMT)
ILS Launch Team
Once the SC in its container was safely inside 92A-50 and after the Globus-1M-3/Proton launch from Pad 24, the team began early in the day to offload the SC and perform a fitcheck. The offload requires highly skilled manpower to meticulously transfer the SC safely off the railcar, unpack it from its container and place it onto the payload adaptor for the fitcheck.
Within the next week, the SC will undergo rigorous testing. During this time, the team will gradually adjust to their new surroundings and time-zone changes (11 hours for ILS and 14 hours for Boeing).

Proton M Ascent Unit Integration Under Way in Preparation for Inmarsat 5F-1 Mission
Proton M/Inmarsat 5F-1 launch campaign continues at the Baikonur Launch Base. The Inmarsat 5F-1 spacecraft is built by Boeing Satellite Systems, U.S.A. for the Inmarsat satellite communication operator, UK.
Yesterday, the international team including engineers and technicians from Khrunichev, the Yuzhny Space Center, Boeing and ILS began integration of the Ascent Unit. They installed the spacecraft on a Breeze M upper stage and then rotated the assembly to a horizontal position. Having run initially through joint electrical checkouts of the stack, the team began installation of the payload fairing halves.
The plan for the next two days includes the completion of Ascent Unit encapsulation followed by PLF tightness prooftesting, checkouts of Ascent Unit electrical connections, and Ascent Unit preparation for being moved to Hall 111 – the area where the Ascent Unit will be integrated with a Proton M launch vehicle.
The contract for using a Proton in support of the Inmarsat 5F-1 mission is concluded by International Launch Services Inc, a Russia/U.S. joint venture headquartered in Reston, VA.
The spacecraft lift-off mass will be about 6000 kilograms and the scheduled launch date is December 8.

Final Proton M ILV Integration for Launching Inmarsat 5F-1: Photo Coverage
Preparations for launching Proton M integrated launch vehicle (ILV) with the Inmarsat 5F-1 spacecraft on board for the Inmarsat telecommunications operator of the UK are proceeding as scheduled.
Main operations to be carried out at Integration-and-Test Facility (ITF) 92A-50 were shifted to Hall 111. On November 30, following the completion of final checkouts in the clean room of Hall 101, the Ascent Unit was moved to Hall 111 for mating to the launch vehicle.
Last weekend, engineers and technicians from Khrunichev as well as from other space-industry companies performed overall Proton M/Inmarsat 5F-1 integration, carried out routine electrical check-outs.
At the moment, the ILV is being processed for roll-out to the Fueling Station where the Breeze M low-pressure tanks will be loaded with propellants. In particular, final electrical checkouts on the Proton ILV and installation of a thermal blanket on the Ascent Unit are to be performed before the end of this day.
The Inmarsat 5F-1 launch is to take place on 8 December.

Earlier this morning, the Proton M ILV has been rolled out to the Fueling Station for loading the Breeze M low-pressure tanks with propellants.
It should take several days to complete fueling operations and then the ILV should be moved to the Launch Pad.
The Briz-M main engine uses prop in low pressure tanks as the engine is fed by a turbopump.
The four 40 kg thrusters use prop in high pressure tanks as they are pressure fed.
This is why Briz does not have a unified fuel system, since the two sets of engines operate in different modes. IF Briz-M had a unified fuel system, then the 40 kg thrusters could be used as backup for the main engine in the event that the main engine should fail during orbital maneuvers.
-
If my memory is correct the deployment of the payload to a super-synchronous altitude from a Proton launch is a rare event. I think this might even be the highest super-synchronous altitude to be used on a Proton launch.

There is really no path to creating a unified fuel system for Briz without effectively re-engineering the entire stage. The 40 kg engines won't work at low fuel pressure, and the Briz main engine does not require high pressure tanks. Making the main engine tanks into high pressure tanks would require significant additional mass.

Khrunichev information about the launch:
The Inmarsat-5F1 mission will be the ninth Proton launch of 2013 and the 392nd Proton flight overall.
This will be the seventh commercial mission of the year for ILS and the 84th ILS Proton mission since the Proton April 1996 first commercial flight.
This will also be the 3rd Inmarsat satellite launched with Proton. In addition, the Inmarsat-5F1 will be the 16th Boeing satellite launched on Proton.
The upper stage follows a five-burn injection profile.
The first burn occurs 94 seconds after the Breeze-M separation from the launcher, forming a parking orbit.
The second ignition is performed in the second descending node of the parking orbit, resulting in an intermediate orbit. The third main engine (ME) burn occurs at the intermediate orbit perigee in an descending node. The ME ignites for the fourth time 137 seconds after the third ME cutoff. The third and fourth ME burns form a transfer orbit with an apogee close to that of the target orbit. The additional propellant tank is jettisoned between the third and the fourth ME burns. The fifth ME burn is performed at the transfer orbit apogee in a ascending node, placing the OU into the target orbit.
The lnmarsat-5F1 satellite is released 12 minutes and 26 seconds after the final ME burn.
The lnmarsat-5F1 injection from liftoff to separation is completed in 55,860 seconds, or 15 hours, 31 minutes and 00 seconds.

OK, not as rare as I thought purely from memory, but still rare. :-)
They seem to be getting more frequent, or perhaps with the start of SpaceX super-sync GTO missions they are simply getting more attention in the United States. I tried to calculate the goodness of the SES-8 delivery orbit:
and my result was a (close) over-estimate of the nominally required delta-v. Musk claimed 1500 m/s and my technique generated 1510.
FWIW using the 4,341 x 65,000 x 26.75 values published for the INMARSAT-5 F1 target orbit, my technique generates 1,475 m/s of delta-v to reach a geostationary orbit. Has ILS published a "delta-v to GEO" value anywhere?
-
The commercial standard for GTO missions is to leave the payload within 1500 m/s of GEO. Note that this 1500 m/s can be either in terms of orbital height, or inclination difference, or some combination of both.
Having a commercial standard for GTO allows launchers to be compared on an "apples to apples" basis, although other factors in evaluating launchers do apply.

I've lost TsENKI feed.
Remember once again that this is a 15h 30m long mission, so still a long way to go...

Great work everyone. I very nearly missed this one, but got back just in time and knew we had you guys covering it! :)
-
Second Briz-M burn is expected to start at 1402:30UTC.
-
Briz-M second firing started at 14:02:30 UTC
-
Briz-M second firing started at 14:02:30 UTC
Still to be confirmed
-
End of second burn was planned for 1422:04UTC

-
Present orbital unit position (red dot)
-
We'll have to wait another while for AOS and confirmation of Briz-M 2nd burn
-
IIANM AOS expected in 10 minutes at 1553:02UTC
-
AOS and 2nd burn OK confirmed (21 seconds short)
-
Orbital unit now right overhead Madrid Spain
-
3rd Briz-M burn planned from 1635:49 until 1645:13UTC

-
AOS and 2nd burn OK confirmed (21 seconds short)
Do you mean that the Briz-M propulsion cut off early?

Do you mean that the Briz-M propulsion cut off early?
Yes, but it's meaningless (1.8% of the nominal duration)

3rd Briz-M burn started as planned.
-
We 'll now have a long loss of signal period which will end before 5th burn
-
APT jettison was planned at 1646:03UTC
4th burn was planned from 1647:30 to 1655:57UTC
-
AOS and 2nd burn OK confirmed (21 seconds short)
Do you mean that the Briz-M propulsion cut off early?
I'd say it has to be the actual duration of a nominal burn. If you follow the successful Proton-M/Briz-M launches in recent years, you'll notice that the second Briz burn is almost always 20~21 seconds short.

We 'll now have a long loss of signal period which will end before 5th burn
AOS (acquisition of TLM signal) is expected at 2206:44UTC
Briz-M 5th burn expected from 0327:05 to 0330:34UTC
S/C separation expected at 0343:00UTC
-
Orbital unit is now over South Pacific for several hours
-
This launch is one of the top stories on the BBC news website due to the British involvement.

One object cataloged as 39476 2013-073A in 360 x 14847 km x 50.8 deg orbit - this is the orbit of the DTB drop tank.
-
AOS expected in a couple of minutes
-
did Britz perform all the burns? (too lazy to look the pdf up)
-
ILS reports 3rd burn, APT jettison and 4th burn completed
-
ILS reports 3rd burn, APT jettison and 4th burn completed
Now confirmed by Khrunichev TM table
-
Briz-M 5th burn completed. Spacecraft separation in 10 minutes.
-
We have spacecraft separation.
-
Congrats to all concerned. Article updated with post success quotes.

My congratulations :) !!!

"The BSS-702HP carries the xenon ion propulsion system (XIPS) for all on-orbit maneuvering."
Is this the first GEO sat with an all XIPS? That capability saved AEHF1 but a confirmation that this is the first to depend on it would be appreciated. Using AEHF as an example, the move to a GEO orbit will be lengthy--months. Is a schedule available somewhere?

Inmarsat-5 F1 is not all XIPS, it has still the usual bipropellant apogee engine. After insertion into GEO, it will use XIPS for on-orbit maneuvering.

After a 15-hour, 31-minute mission, the satellite was placed into the target orbit by the Proton launcher.

Object B which could be the spacecraft has now been catalogued:
39477/2013-073B in 4306 x 64810 km x 26.65°
-
Objects 2013-073A and 2013-073B have now been switched; A becomes the S/C
-
AFAIU Briz-M hasn't been catalogued

AFAIU Briz-M hasn't been catalogued
I rather think the object cataloged in the 4300 x 64800 km orbit
is the Briz-M, and it's the payload that hasn't been found yet.
You'd expect an orbit manuever by the payload by now, no?

The 4 304 x 64 839 km x 26.64° orbit is dated December 11 and is close to the published by Khrunichev achieved S/C injection orbit which was 4251 x 64889 km x 26.76°. Remember that Briz-M performed 2 more firings (one of 15 seconds, the other of 100 seconds) after S/C separation and should be in a very different orbit...
-
Object A, the spacecraft, was in the following orbit at epoch Dec 15, 1141UTC:
30722 x 65023 km x 2.06°
Briz-M doesn't seem to have been catalogued

The first telemetry signal was acquired by our Paumalu ground station in Hawaii at 17:48 UTC, putting the satellite under the control of Inmarsat’s mission operations team.

Yeah, the top post by input~2 on this page says it. The Live status...my bad ???
I-5 satellites will deliver high-speed mobile broadband communications for deep sea vessels, in-flight connectivity for airline passengers, streaming high-resolution video, voice and date to the enterprise sector, and secure solutions for government customers.
Dear Santa... :P
In a decade or so, I shall own a few Satellites to empower my nation.

1st Boeing Built Inmarsat-5 Satellite Successfully Completes On-Orbit Testing
Satellite handed over for high-speed broadband service
EL SEGUNDO Calif., March 11, 2014 -- Boeing's [NYSE: BA] first of four satellites for Inmarsat's Global Xpress network, has passed all of its on-orbit testing and has now been handed over to Inmarsat.
"This is an important milestone for Global Xpress," said Rupert Pearce, CEO of Inmarsat. "The testing of the Boeing built platform and payload has been completed and shown to meet all the specifications. This is a testament to the dedication of Inmarsat’s Global Xpress team and the skill and professionalism of our partners: Boeing and iDirect."
The high-speed mobile broadband satellite, launched on Dec. 8, will support a wide range of government and commercial customer uses, including in-flight connectivity, communications for vessels at sea, streaming video and other voice and data services.
"This delivery is the first of the significant milestones we expect to accomplish during this landmark year in the Boeing-Inmarsat relationship," said Craig Cooning, chief executive officer of Boeing Satellite Systems International.
Boeing is under contract to build four Inmarsat-5 satellites, with two more scheduled for completion and launch by the close of 2014. The fourth satellite is scheduled to be delivered in 2016. The Inmarsat-5 satellites carry a secondary payload that Boeing Commercial Satellite Services will lease to potential government customers through a reseller agreement with Inmarsat.
