At the Baikonur cosmodrome the international team including engineers and technicians from Khrunichev, the Yuzhny Space Center, Boeing and ILS began integration of the Ascent Unit (Inmarsat 5F3/adapter/Briz-M/PLF stack). The plan includes mating of the spacecraft to the Briz-M upper stage followed by bringing the Spacecraft/Briz-M stack into a horizontal position. On completion of this mating procedure, the Boeing specialists will perform electrical check-outs of the spacecraft.

Proton M/Breeze M
705,000 kg (1,554,000 lb), including payload
58.2 m (191ft)
Launch Date:
August 28, 2015
Launch Time:
17:44 Baikonur
14:44 Moscow
12:44 London

07:44 ET
Launch Site:
Baikonur Cosmodrome, Kazakhstan
Launch Pad 39
Launch Customer:
Inmarsat, London, England
Satellite Manufacturer:
Boeing Satellite Systems International, California, USA
Launch Vehicle Manufacturer:
Khrunichev State Research and Production Space Center,
Moscow, Russia
Launch Services
Provider:
International Launch Services, Virginia, USA
Satellite Use:
Inmarsat Global Xpress (GX) will be the first globally available high-speed mobile
broadband network delivered by a single operator. It will be delivered over an initial
fleet of three Inmarsat-5 satellites and will offer the unique combination of global
coverage and the network reliability for which Inmarsat is renowned. Based on Ka-band
technology, GX will consistently deliver higher performance through more compact
terminals at a lower cost than existing VSAT services, making it accessible to many
more users.
Satellite Statistics:
__89 ka-band transponders
__Planned orbital location: 55° W
__Anticipated service life: 15 years
Mission Profile:
The Proton M launch vehicle, utilizing a 5-burn Breeze M Supersynchronous Transfer
Orbit mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan,
with the Inmarsat-5 F3 satellite on board. The first three stages of the Proton will use a
standard ascent profile to place the orbital unit (Breeze M upper stage and the
Inmarsat-5 F3 satellite) into a sub-orbital trajectory. From this point in the mission, the
Breeze M will per-form planned mission maneuvers to advance the orbital unit first to a
circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and
finally to a supersynchronous transfer orbit. Separation of the Inmarsat-5 F3 satellite is
scheduled to occur approximately 15 hours, 31 minutes after liftoff.
Target Orbit at Separation:
Perigee: 4,341km
Apogee: 65,000 km
Inclination: 26.75 degrees
Spacecraft Separation:
Approximately 15 hours, 31 minutes after lift-off
ILS Mission Statistics:
_ 3rd ILS Proton Launch in 2015
_90 th ILS Proton Launch Overall
_ 5 th Inmarsat Satellite Launched on Proton
_19 th Boeing Satellite Launched on Proton

Every so often Doug has a gem of a tweet.
Parabolicarc.com (@spacecom) tweeted at 0:23 PM on Fri, Aug 28, 2015:
Inmarsat set for key launch http://t.co/L9vV0C5Fto Worry not. Protons usually good right after failure. A few launches later not so much
(https://twitter.com/spacecom/status/637057762241851392)
The last back-to-back Proton failures were in 1988 with a Gorizont on 18 January and three GLONASS satellites failing to separate on 17 February. Other back-to-backs were in 1986/1987 and 1978. There were four consecutive failures in 1969/1970 and 1969, two consecutive failures in 1968 and three consecutive failures in 1967.

No live telemetry from Khrunichev again so we'll have to rely on ILS to provide updates.

Anyone knows if the 2nd Briz-M burn is nominal? ILS isn't going to update until after the 4th burn.
2nd burn was 2% longer than nominal
Any issue with that?

Don't think it's an issue (1197s instead of 1174s planned)
Intermediate orbit estimated at 301.7 km x 6008.4 km x 51° vs 302.0 x 6007.0 x51° nominal

Press Release:ILS PROTON SUCCESSFULLY LAUNCHES INMARSAT-5 F3 SATELLITEThe Final Global Xpress®Satellite Launch in 3-constellation SeriesBAIKONUR COSMODROME, Kazakhstan, August 29, 2015 – An International Launch Services (ILS) Proton Breeze M successfully placed the Inmarsat-5 F3 (I-5 F3) satellite into a super-synchronous transfer orbit (SSTO) today. The spacecraft was launched for Inmarsat, the leading provider of global mobile satellite communications services. I-5 F3 is the third of Inmarsat’s next-generation Global Xpress satellites, which launched on an ILS Proton. This marks the third Proton launch of the year and the 5th SSTO mission for ILS, a leader in providing launch services to the global commercial satellite industry.
The Proton launch vehicle, carrying the I-5 F3 satellite, lifted off from Pad 39 at the Baikonur Cosmodrome yesterday at 17:44 local time (12:44, London time, 11:44 GMT and 07:44 ET). The SSTO mission utilized a 5-burn Breeze M mission design to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a 65,000 km-apogee super-synchronous transfer orbit. After a 15-hour, 31-minute mission, the satellite was placed into the target orbit by the Proton launcher. SSTO missions provide increased heavy-lift performance over GTO mission designs, allowing our customers the capability to maximize spacecraft operational lifetime.
The satellite was manufactured by Boeing Satellite Systems International and built on the reliable 702HP platform. Weighing over 6 metric tons at lift-off, the I-5 F3 satellite has 89 Ka-band fixed beams and 6 steerable ones. I-5 F3 is designed to generate approximately 15 kilowatts of power at the start of service and approximately 13.8 kilowatts at the end of its 15-year design life. To generate such high power, the spacecraft's two solar wings employ five panels of ultra-triple-junction solar cells.
Global Xpress will be the first globally available high-speed mobile broadband network, delivered through a single provider. It will offer the unique combination of global coverage, consistent high-speed performance, and the network reliability for which Inmarsat is renowned. GX services will be deployed to serve the advanced mobility needs of Inmarsat’s existing customers on land, at sea and in the air, will diversify Inmarsat’s business into existing adjacent government and energy markets, and position Inmarsat in the vanguard of new, high-growth military-Ka, aviation passenger, maritime and other connectivity markets.
ILS President Phil Slack stated, “It is always exciting to launch a satellite for one of our customers and to play a key role in the deployment of its services. As the launch provider for Inmarsat’s first three Global Xpress satellites, it has been extremely rewarding to know that we have helped to enable Inmarsat’s innovative technology. Inmarsat’s Global Xpress network delivers broadband connectivity to the remotest regions of the world, as well as critical worldwide communications services on land, at sea or in the air. The collective teams at Inmarsat, ILS, Khrunichev and Boeing are to be commended for their dedication to the successful launch of Inmarsat-5 F3.”
“The launch of the third Global Xpress satellite is a pivotal moment in Inmarsat’s history. Global Xpress will delivery broadband speeds an order of magnitude faster than our 4th generation (I-4) constellation, allowing us to offer our current customers new high value services and solutions and to grow our business activities into exciting new markets. This is truly a new era in mobile satellite communications,” said Rupert Pearce, CEO, Inmarsat. “We sincerely thank our dedicated staff and our partners at Inmarsat, Boeing, ILS and Khrunichev for ensuring mission success.”
The I-5 F3 launch marked the 405th launch for Proton since its maiden flight in 1965 and the 90th ILS Proton Launch overall. This was also the 19th Boeing-built satellite launched on an ILS Proton and the 5th Inmarsat satellite launched on Proton overall. The Proton M Breeze M vehicle is developed and built by Khrunichev Research and Production Space Center of Moscow, Russia’s premier space industry manufacturer and majority shareholder in ILS.

Inmarsat press release:
Inmarsat confirms successful launch of the third Global Xpress (GX) satellite
Globally available GX services on course to start before the end of 2015
29 August 2015 – Inmarsat (LSE:ISAT.L), the leading provider of global mobile satellite communications services, has confirmed the successful launch of its third satellite in the transformational Global Xpress (GX) constellation. Inmarsat-5 F3 (I-5 F3), which was launched from the Baikonur Cosmodrome in Kazakhstan at 12.44pm (BST), entered orbit this morning at 04.15 am (BST) following a 15 hour and 31 minute mission.
Over the coming weeks, the Inmarsat Operations Team will raise I-5 F3 to its final orbit, deploy its solar arrays and reflectors, and undertake payload testing. At the end of these procedures, I-5 F3 will be ready to join the first two GX satellites, which are already in orbit and operating successfully, to create the first, globally available, high-speed mobile broadband network delivered by a single operator.
Rupert Pearce, CEO of Inmarsat, said: “We have been working towards this day ever since we announced plans to create the Global Xpress constellation in 2010. I am delighted that we now have three Global Xpress satellites in orbit, enabling us to provide global GX services by the end of the year.
“This is a significant milestone for Inmarsat; one that will offer major growth opportunities and promises to change the face of our industry.
“Global Xpress will deliver broadband speeds that are an order of magnitude faster than our fourth generation (I-4) constellation, to customers on the move on land, at sea and in the air, globally. As such, the GX fleet will offer a host of new opportunities for both our existing and new customers to significantly enhance their connectivity capabilities and to deploy bandwidth-hungry applications and solutions efficiently and effectively, even in the remotest and most inaccessible parts of the world. Global Xpress is, therefore, an important enabler for continued growth in global mobile broadband - it is the ‘Internet of Everywhere’.
“I would like to thank our dedicated team of engineers for their outstanding work in making Global Xpress a reality in just five years. It is an amazing achievement to design, manufacture and successfully launch three advanced communication satellites in such a short time. I would also like to extend my thanks to our satellite manufacturing partner Boeing and our launch partners ILS and Khrunichev for delivering a successful outcome today.”
The first Global Xpress satellite – Inmarsat-5 F1 – was launched in December 2013 and entered commercial service in July 2014, covering Europe, the Middle East, Africa and Asia. This was followed by the launch of Inmarsat-5 F2 on 1st February 2015, which covers the Americas and the Atlantic Ocean and entered commercial service this month (August).

Boeing-built Satellite Will Create First Global High-Speed Broadband Network
Third Inmarsat-5 satellite with new technology will allow global coverage
EL SEGUNDO, Calif., Aug. 29, 2015 – When the third Boeing-built [NYSE: BA] Inmarsat-5 satellite, which is now in orbit, becomes fully operational later this year it will provide the technology and coverage necessary for worldwide high-speed broadband access.
Inmarsat-5 F3 sent signals from space following its launch yesterday on an International Launch Services Proton Breeze M launch vehicle. After reaching final orbit, the spacecraft will undergo testing and checkout before becoming operational.
“The Inmarsat Global Xpress network will be the first high-speed Ka-band broadband network to span the world,” said Rupert Pearce, CEO, Inmarsat. “New technology and engineering design will allow us to steer capacity where it’s needed most and adjust to shifting subscriber usage patterns and evolving demographics over the minimum 15-year life span of the network. We can now look forward to the introduction of global GX commercial services by the end of this year.”
Each of the three Inmarsat-5 satellites use fixed narrow spot beams to deliver higher speeds through more compact terminals. Steerable beams direct additional capacity in real-time to where it’s needed to provide seamless, global broadband communications coverage to Inmarsat users worldwide on land, at sea, and in the air. The first two Inmarsat-5 Global Xpress satellites were launched December 2013 and February 2015, respectively. A fourth Boeing-built Inmarsat-5 (F4) is scheduled for delivery in mid-2016.
“The 702HP (high power) satellite is ideally suited for delivering the advanced capabilities Inmarsat required for this mission,” said Mark Spiwak, president, Boeing Satellite Systems International. “More than 20 of these 702HP spacecraft are in orbit now for customers, including Inmarsat, providing reliable, affordable and innovative service.”
Boeing has a strategic marketing partnership with Inmarsat and currently provides both military Ka-band and commercial Global Xpress services to U.S. government customers. Boeing recently concluded an extensive demonstration program for ten U.S. government customer communities using the Inmarsat-5 F2 spacecraft.
