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.

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.

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.

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.

I've had trouble getting Tsenki to work. A solution I've found is to use VLC Media Player and play the following link (Media -> Open Network Stream...). You can then adjust the screen to the correct 16:9 format.

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

Also it seems that only the ILS cameraman has problems with tracking - on the TsENKI stream they have good images of 1st stage separation.  :-[

Press Release: (http://www.ilslaunch.com/newsroom/news-releases/ils-proton-successfully-launches-inmarsat-5-f3-satellite)

ILS PROTON SUCCESSFULLY LAUNCHES INMARSAT-5 F3 SATELLITE

The Final Global Xpress®Satellite Launch in 3-constellation Series

BAIKONUR 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.

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.
