Ariane 5   August 21, 2017
Flight VA239: Launcher and payload preparations advance for Arianespace’s next Ariane 5 liftoff

The Ariane 5 for Arianespace’s ninth flight in 2017 is being readied for a September 5 liftoff from the Spaceport, while its two satellite passengers – Intelsat’s Intelsat 37e and BSAT-4a for SSL on behalf of Japan’s Broadcasting Satellite System Corporation (B-SAT) – continue their final checkout at the French Guiana facility.

Following its build-up in the Launcher Integration Building, the Ariane 5 has been moved to the Final Assembly Building for the upcoming installation of Intelsat 37e and BSAT-4a – which are now undergoing their own checkout processes in separate halls of the Spaceport’s S5 payload preparation facility.

The upcoming mission to geostationary transfer orbit is designated Flight VA239 in Arianespace’s numbering system, and will mark the 239th launch of an Ariane vehicle since the European launcher series entered service in 1979. The heavy-lift Ariane 5 is operated as part of Arianespace’s launcher family at the Spaceport, which also includes the medium-lift Soyuz and lightweight Vega.

An “Epic” launch at the service of Intelsat

Built by Boeing using a 702MP spacecraft platform, Intelsat 37e is the next satellite in Intelsat’s high-throughput EpicNG series for launch.

It also will be the fourth EpicNG spacecraft orbited by Arianespace to date (following Ariane 5 missions with Intelsat 29e and Intelsat 33e in January and August 2016, respectively, plus last February’s heavy-lift flight that lofted SKY Brasil-1/Intelsat 32e).

Operating in the C, Ku and Ka frequency bands, the spacecraft will provide capacity for wireless backhaul, enterprise VSAT and mobility networks. Intelsat 37e, which is to carry out its mission from a 342-deg. East orbital slot, will weigh approximately 6,440 kg. at liftoff.

Continuing a long and fruitful partnership

Arianespace is launching Flight VA239’s co-passenger, BSAT-4a, as part of a turnkey contract between B-SAT and U.S.-based satellite manufacturer SSL. To be operated from an orbital position of 110 deg. East, this spacecraft will be used for Direct-To-Home (DTH) television relay in Japan and to expand the availability of advanced television services – such as 4K/8K ultra-high definition TV.

BSAT-4a is based on the SSL 1300 satellite platform and is fitted with 24 Ku-band transponders. It will weigh approximately 3,520 kg. at liftoff, with a design life that exceeds 15 years.

Arianespace has a 30-year-plus track record serving operators in the Japanese market – including B-SAT, for which it is the launch services provider of choice.

Flight VA239 will continue Arianespace’s busy schedule in 2017, in which eight launches were performed during the year’s first seven months, utilizing the company’s full launcher family (two with Vega; two with Soyuz; and four using Ariane 5).

Ariane 5 is completed for its dual-payload mission on September 5

The Ariane 5 for Arianespace’s ninth mission of 2017 is now fully assembled following integration of its two satellite passengers at the Spaceport in French Guiana.

During activity in Ariane 5’s Final Assembly Building, the upper payload component – containing Intelsat 37e, mounted on its SYLDA dispenser system and protected by an ogive-shaped fairing – was lowered into position over BSAT-4a, which previously was installed atop the launcher’s central core.

This step clears the way for final checkout, which will enable the launch readiness review to be conducted on September 1, followed by Ariane 5’s rollout to the Spaceport’s ELA-3 launch zone the following Monday, and an evening liftoff on Tuesday, September 5.

The upcoming mission is designated Flight VA239 in Arianespace’s numbering system, and it will deliver the two telecommunications payloads into geostationary transfer orbit.

Telecommunications satellites from long-time customers

To be deployed first during the 47-minute flight sequence is Intelsat 37e – the next satellite in Intelsat’s high-throughput EpicNG series for launch, which was built by Boeing using a 702MP spacecraft platform. This spacecraft will operate in C, Ku and Ka frequency bands, providing capacity for wireless backhaul, enterprise VSAT and mobility networks from a 342-deg. East orbital slot. Intelsat 37e has an estimated liftoff mass of 6,438 kg.

Ariane 5’s second passenger – BSAT-4a, which is being launched as part of a turnkey contract between Japan’s Broadcasting Satellite System Corporation (B-SAT) and U.S.-based satellite manufacturer SSL – will be operated from an orbital position of 110 deg. East. It will be used for Direct-To-Home (DTH) television relay in Japan, as well as to expand the availability of advanced television services (such as 4K/8K ultra-high definition TV). BSAT-4a will weight approximately 3,520 kg. at liftoff.

Flight VA239 will continue Arianespace’s busy schedule in 2017, in which eight launches were performed during the year’s first seven months, utilizing the company’s full launcher family (two with Vega; two with Soyuz; and four using Ariane 5).

Could a strong solar flare from Active Region (10)2673 delay this launch?  The sunspot group is oriented such that a flare now would be geoeffective.

Ariane 5 reaches the launch zone for tomorrow’s dual-satellite mission

Arianespace has delivered another Ariane 5 to the launch zone at Europe’s Spaceport in French Guiana, positioning the heavy-lift vehicle for its September 5 flight with two telecommunications satellites: Intelsat 37e and BSAT-4a.

Riding atop a mobile launch table, Ariane 5 was transferred to the ELA-3 launch zone from the Spaceport’s Final Assembly Building – where its two passengers had been integrated as part of pre-flight preparations.

With the rollout now completed, the final countdown will begin for a liftoff tomorrow at the start of a 33-min. launch window that opens at 6:51 p.m. local time in French Guiana.

For this 239th launch of an Ariane-series vehicle – designated Flight VA239 in Arianespace’s numbering system – the payload lift performance to geostationary transfer orbit is an estimated 10,838 kg. The total factors in the mass of Intelsat 37e and BSAT-4a, plus the launch vehicle’s dual-passenger dispenser system and satellite integration hardware.

Intelsat 37e is riding as the upper passenger in Ariane 5’s payload arrangement, to be released 29 minutes into tomorrow’s mission. The spacecraft, with a liftoff mass estimated at 6,438 kg., was built for Intelsat by Boeing using a 702MP platform, and will operate from an orbital position of 342 deg. East.

BSAT-4a – whose launch is part of a turnkey contract between Japan’s Broadcasting Satellite System Corporation (B-SAT) and U.S.-based manufacturer SSL – will be deployed from Ariane 5’s lower passenger position. Based on the SSL 1300 platform, this satellite’s separation will occur 47 minutes after liftoff – completing Arianespace’s September 5 mission. BSAT-4a has an estimated liftoff mass of 3,520 kg. and will operate from a 110 deg. East orbital slot.

No. To my knowledge, there's been two others: one in December 2002, which included the first failed Ariane 5ECA; and one in March 2011, which included a previous Intelsat satellite.

Thanks, that was probably just before I started watching them on a regular basis when the shuttle program ended, looks kind of similar to a shuttle abort at that.

I watched from ~T-4:00. My impression is the following:
Umbilical retraction was late @ T-0:05 instead of T-0:07.
As consequence, the Vulcain 2 engine started late and wasn't running stable at the check-point before the solid are ignited. (@T+0:07 if I'm not mistaken.)

They have to roll the launch table back to BAF to reconnect the umbilical arms and connectors.
And to replace igniters on the Vulcain2 engine.

From Memory: minimum 5 day recycle is required for reconnecting the separated umbilicals alone.
Day 1 vehicle safing, De-arming/servicing prior to rollback.
Day 2 Table disconnect from pad, Rollback, connect table in BAF
Day 3 Umbilicals reconnect
Day 4 Table disconnect from BAF, Rollout, connect table in Pad
Day 5 Launch day

If that's the case, then this recycle sequence places the second try on September 9.

Prestart seemed slow and did not reach flight thrust in time of check point. the mixture ration kept the flame orange instead of the normal blue with Mach diamonds.

From my point of view, Vulcain 2 was up and running at H0+5,5 s - as it should.
The nominal ignition sequence only starts at H0+1 s (in contrast to Vulcain 1 at H0) and chamber ignition itself only happens at around H0+2 s.

The SRBs ignite at H0+7.3 seconds (or T0, as I see it).

The SRBs, however, never ignited because during the brief health check of the Vulcain 2 engine, the startup problem was detected and the engine shut down.

I've never understood why they disconnect the umbilicals before launch commit. It has always seemed very optimistic.

I've never understood why they disconnect the umbilicals before launch commit. It has always seemed very optimistic.
The umbilicals that are retracted 5 seconds before Vulcain ignition are the LOX and LH2 propellant umbilicals for the upper stage (ESC-A). These don't need to be T+7 (= launch commit) umbilicals given that they only transfer propellant into the ESC-A stage. It is OK to stop topping-off the ESC-A propellant tanks several seconds before ignition of the main engine.
Purging the ESC-A propellant tanks after a pad abort is done via several T+7 "pull-out" umbilicals that carry-away gaseous oxygen and gaseous hydrogen.

Anomaly causes interruption of the countdown for Arianespace Flight VA239

During the final seconds of the launch countdown for Arianespace Flight VA239, the checkout process detected an anomaly on the launcher as the Vulcain cryogenic main stage engine was being ignited. As a result, the final countdown was interrupted.

The Ariane 5 and its Intelsat 37e and BSAT-4a payloads immediately switched to a safe mode. Analysis of data is underway to determine the cause of the anomaly. In parallel, the launcher will be transferred back to the Final Assembly Building at the Spaceport in French Guiana – where it is to be returned to a flight-ready condition.

Arianespace will set a new launch date as soon as possible.

Any word from ESA on how quickly VA239 can be turned around? I imagine that, if nothing else, the Vulcan will need to be thoroughly checked.

I know but the engine was ignited so they will want to make sure that it hasn't been affected by that.

As with gas generator cycle engines like the Vulcain 2, they are ignited in two steps: chamber and gas generator.
The first flash you can see is the chamber ignition. And the mach diamond is nominally coming very late. Yesterday the camera switched away from the engine before the nominal time of formation of the mach diamond.

Are the SRB bolted down and can these bolts hold the upward forces from the SRBs? If yes I guess they would the one burn out. If not, then there will be a lot of fireworks  :P

Something similar to this wonderful quote from Chris back in 2007 about the shuttle (Nothing beats google for searching NSF 8)).

They did a simulation apparently, and depending on which SRB doesn't light, it'd lift off and cartwheel into the ocean, or into the LCC. If you were at the press site, you'd be toast.

The umbilicals that are retracted 5 seconds before Vulcain ignition are the LOX and LH2 propellant umbilicals for the upper stage (ESC-A). These don't need to be T+7 (= launch commit) umbilicals given that they only transfer propellant into the ESC-A stage. It is OK to stop topping-off the ESC-A propellant tanks several seconds before ignition of the main engine.
Purging the ESC-A propellant tanks after a pad abort is done via several T+7 "pull-out" umbilicals that carry-away gaseous oxygen and gaseous hydrogen.

I understand that the umbilicals are not required for the last seconds before a launch, but that misses my point. It is still not very smart (as highlighted by this very scrub) to disconnect them before you absolutely have to.

Perhaps they are worried about the opposite - the vehicle takes off and the umbilicals do not detach.   This might be even worse than a pad abort.   So detach, then verify, then launch.  If they are wrong, it's only a few days, not loss of mission.

Can they drained the fuels normally without reattaching the umbilicals? Is't the tanks refilled with helium?

The umbilicals that are detached at T-5 seconds are the umbilicals for carrying LOX and LH2 INTO the ESC-A upper stage. So, these are umbilicals for propellant LOADING.
There is second set of "hung" umbilicals, of the "pull-out/pull-off" type for UNLOADING of gaseous Oxygen and Hydrogen. Those umbilicals detach when the launcher rises off the launchpad during launch.
When a pad abort on a Ariane 5 ECA takes place the propellants in the ESC-A are allowed to simply boil-off with the gaseous Oxygen and Hydrogen being carried away via the UNLOADING umbilicals.

From the top of my head: returning the ESC-A to launch-ready condition requires re-attaching the umbilicals for propellant loading as well as check-out of all attached umbilicals. Additionally all tanks and propellant lines are purged again to get rid of possible contaminants. Helium supply (for propellant tank pressurization) is topped-off as well as all electrical circuits re-checked. Reloading of the propellant tanks naturally takes place only after the launcher is returned to the launch site.

Ariane 5   September 28, 2017
Ariane 5 is in the launch zone for Arianespace’s mission with Intelsat 37e and BSAT-4a

The Ariane 5 for tomorrow’s Arianespace flight with a pair of telecommunications satellites has moved to the launch zone at the Spaceport in French Guiana, positioning it for an evening liftoff to geostationary transfer orbit with the Intelsat 37e and BSAT-4a payloads.

For this ninth Arianespace mission of 2017, the Ariane 5’s rollout occurred today – with the vehicle riding atop one of two operational launch tables for its return to the pad. Tomorrow’s mission is designated Flight VA239 in Arianespace’s numbering system for its launcher family, and will deliver a total payload lift performance of approximately 10,840 kg.

To be released first during the 47-minute mission will be Intelsat 37e – becoming the fourth EpicNG spacecraft orbited by Arianespace for Intelsat. This Boeing-built spacecraft, based on the 702MP platform, is the first to offer interconnectivity between three different bands. It is designed to deliver high-performance service in C-, Ku- and Ka-bands for use in wireless backhaul, enterprise VSAT and mobility networks.

Flight VA239’s BSAT-4a passenger will be launched by Arianespace for satellite manufacturer Space Systems Loral in the framework of a turnkey contract with Japan’s Broadcasting Satellite System Corporation (B-SAT). To be utilized for Direct-to-Home (DTH) television service in Japan, BSAT-4a is based on Space Systems Loral’s SSL 1300 platform. The relay platform is equipped with 24 Ku-band transponders and will expand the availability of advanced television services such as high definition and 4K/8K ultra-high definition.

Galileo satellites are readied for Flight VA240 in December

In other activity at the Spaceport, the first two satellites for Arianespace’s Flight VA240 with Ariane 5 have begun their checkout. Targeted for a liftoff on December 12 carrying a quartet of Galileo navigation spacecraft, this mission will be performed on behalf of the European Commission under a contract with the European Space Agency (ESA).

Arianespace already has launched 18 Galileo spacecraft, with four being deployed into medium Earth orbits on a previous Ariane 5 mission (Flight VA233 in November 2016), and the others lofted by seven medium-lift Soyuz vehicles carrying two satellites each.

Galileo is designed to provide a European global satellite navigation system with precision positioning services under civilian control.

Ariane 5   September 29, 2017
Flight VA239: Arianespace orbits Intelsat 37e and BSAT-4a on 81st successful Ariane 5 launch in a row

Arianespace has successfully launched the Intelsat 37e communications satellite for the operator Intelsat, along with the BSAT-4a digital TV broadcast satellite for manufacturer SSL (Space Systems Loral) as part of a turnkey contract with Broadcasting Satellite System Corporation (B-SAT) of Japan.

The launch took place on Friday, September 29 at 6:56 p.m. (local time in Kourou) from the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana (South America).

With this ninth launch of the year, and the fifth by Ariane 5, Arianespace also logged the 81st successful launch in a row by the Ariane 5 heavy launcher.

Boosting innovative space communications

Intelsat 37e is the 59th Intelsat satellite to be launched by Arianespace since Intelsat 507 was orbited in October 1983. The Arianespace order book includes two more satellites from this operator (Intelsat 39 and Horizon-3e).

With its state-of-the-art digital payload, Intelsat 37e offers the highest throughput in the Intelsat EpicNG fleet. It features an improved power-sharing technology that allows it to assign onboard power between shaped, fixed and steerable Ku-band spot beams.

The satellite’s services can be optimized on demand, depending on application requirements and by region, thus boosting its ability to provide ever more effective transmissions for mobile and government customers in the Americas, Africa and Europe.

Arianespace and Boeing

Intelsat 37e is the 55th Boeing-built satellite to be launched by Arianespace since 1987.
The Arianespace order book includes two more Boeing satellites: Horizon-3e and ViaSat 3F1.
Intelsat 37e is the fifth high-throughput satellite in the Intelsat EpicNG series, and the fourth of this series to be launched by Arianespace, reflecting Intelsat’s exceptional trust in the launch services offered by Arianespace.

The BSAT-4a satellite was launched for SSL within the scope of a turnkey contract with the Japanese operator Broadcasting Satellite System Corporation (B-SAT).

BSAT-4a is the ninth B-SAT satellite launched by Arianespace. It will offer direct-to-home (DTH) digital broadcast services across Japan. Its 24 Ku-band transponders will support the expansion of the most advanced DTH services, including high-definition and very-high-definition (4K/8K).

Arianespace and SSL

BSAT-4a is the 64th satellite with an SSL platform to be launched by Arianespace since 1983.
The Arianespace order book includes three more SSL satellites: Azerspace2/Intelsat-38, Eutelsat 7C, and Intelsat 39.
Arianespace has launched all B-SAT satellites since the Japanese operator’s creation. Reflecting its unmatched position in this market, BSAT-4a is the 29th geostationary satellite launched by Arianespace for a Japanese operator.

Arianespace’s heavy launcher: combining reliability and performance

With today’s mission, the 81st successful launch in a row for Ariane 5, Arianespace’s heavy launcher has once again proven its unrivaled reliability and performance. It also nearly equaled the launcher’s payload record of 9,969 kg, set by flight VA237 in June 2017, by lofting a net payload weight of 9,958 kg.

Arianespace has carried out nine launches from the Guiana Space Center to date in 2017 (five by Ariane 5, two by Soyuz and two by Vega). Since the beginning of the year, the company has launched 15 payloads – including 12 into geostationary transfer orbit – totaling 55,440 kg.

Shortly after the announcement of the orbital injection of the two satellites, Stéphane Israël, CEO of Arianespace, said: “Arianespace is proud to share this fifth successful Ariane 5 launch of the year, its 81st in a row, with our American and Japanese customers. We are very happy with the continuing expression of trust from Intelsat. Just slightly over a year after the dual launch of IS-33e and IS-36, and seven months after the launch of Intelsat-32e/SKY Brasil-1, we have now orbited Intelsat-37e, the most powerful satellite in its Intelsat EpicNG fleet. Congratulations to Boeing, our long-standing partner, which built Intelsat 37e, and with whom we have carried out the third mission of the year from CSG. Our thanks also go to SSL, manufacturer of BSAT-4a, with whom we have a very long and valued relationship, having now launched a total of 64 satellites based on SSL platforms, as well as B-SAT, which has entrusted us with the launch of its entire fleet of satellites, a special honor for us.

“I would like to congratulate all our partners on this 95th Ariane 5 launch: everyone at our parent company, ArianeGroup, along with their partners from industry who work on Ariane launchers; ESA, for its active support of the Ariane program; CNES/CSG, our ground segment companies, and all staff at the space center, who work alongside us as we go from success to success. And of course, I would like to congratulate everyone at Arianespace for the success of our ninth launch of the year.”

Intelsat 37e, a next generation fixed and mobile communications satellite, will operate in C, Ku and Ka bands, providing high-quality, high-speed connections. Built by Boeing using a 702MP platform, the satellite will operate from geostationary orbit at 342° East. Its coverage zone includes the Americas, Europe and Africa. It weighed 6,438 kg at launch and offers a design life of 15 years.

The BSAT-4a satellite is dedicated to digital broadcasting, based on an innovative payload for high-definition and ultra-high-definition (4K/8K) TV broadcasts. Built by SSL using the 1300 platform, it will operate from geostationary orbit at 110° East, and will cover Japan. It weighed 3,520 kg at launch and offers a design life of 15 years.

Ariane 5 orbits Intelsat 37e and BSAT-4a on Arianespace’s latest mission from the Spaceport

Arianespace orbited telecommunications satellites for long-time customers on today’s successful mission – confirming the company’s role as a launch services leader in terms of availability, reliability and performance.

Conducted from the Spaceport’s ELA-3 launch zone in French Guiana, the successful mission delivered an estimated payload lift performance of 10,838 kg. to geostationary transfer orbit (GTO) – utilizing the heavy-lift Ariane 5 member of Arianespace’s launcher family, which also includes the medium Soyuz and lightweight Vega.

Designated Flight VA239, the mission carried Intelsat 37e for global operator Intelsat; along with BSAT-4a, which was launched as part of a turnkey contract between Japan’s Broadcasting Satellite System Corporation (B-SAT) and U.S.-based satellite manufacturer SSL. Intelsat 37e was deployed first in the flight sequence, separating from Ariane 5 at 29 minutes after liftoff, followed approximately 18 minutes later by BSAT-4a.

Another “Epic” launch for Intelsat

Intelsat 37e – built by Boeing using a 702MP platform – is the latest satellite from Intelsat’s high-throughput EpicNG series to be launched. It also marks the fourth EpicNG spacecraft orbited by Arianespace to date (following Ariane 5 missions with Intelsat 29e and Intelsat 33e in January and August 2016, respectively, plus last February’s heavy-lift flight that lofted SKY Brasil-1/Intelsat 32e).

Overall, Intelsat 37e is the 59th Intelsat satellite launched by Arianespace since 1983, as well as the 55th Boeing-produced spacecraft orbited by the company – continuing a partnership that extends back to 1987. Arianespace’s order book includes three more satellites to be lofted for Intelsat. Two Boeing payloads are in the Arianespace order book for future missions: Horizon-3e and ViaSat 3F1.

Weighing an estimated 6,440 kg. at liftoff, Intelsat 37e will provide capacity for wireless backhaul, enterprise VSAT and mobility networks, carrying out its mission from a 342-deg. East orbital slot.

The launch leader for Japan

The second-released passenger on today’s successful Ariane 5 flight, BSAT-4a, will be used for Direct-To-Home (DTH) television relay in Japan, as well as to expand the availability of advanced television services (such as 4K/8K ultra-high definition TV). It will operate from a final orbital position of 110 deg. East.

Arianespace has launched all B-SAT satellites since this company’s creation, reflecting an unmatched position in the market. Since 1989, Arianespace has lofted a total of 29 GTO satellites for Japanese operators, representing more than 75 percent of the Geostationary Earth Orbit (GEO) market share in Japan.

Arianespace’s launch of BSAT-4a also continues its long-running partnership with SSL, having now launched a total of 64 satellites produced by this manufacturer since 1983 – with three more in the company’s order book (Azerspace2/Intelsat-38, Eutelsat 7C, and Intelsat 39).

Arianespace’s 2017 launch calendar

Flight VA239 was Arianespace’s ninth launch in 2017, and it follows other heavy-lift Ariane 5 missions performed this year on February 14 (carrying SKY Brasil-1 and Telkom 3S), May 4 (SGDC and KOREASAT-7), June 1 (ViaSat-2 and EUTELSAT 172B) and June 28 (Hellas Sat 3-Inmarsat S EAN and GSAT-17).

Also conducted earlier in 2017 were Arianespace’s medium-lift Soyuz missions on January 27 (with Hispasat 36W-1) and May 18 (SES-15); plus light-lift Vega flights performed March 6 (Sentinel-2B) and August 1 (OPTSAT-3000 and Venµs).

Arianespace’s next mission – a Vega flight at the service of Thales Alenia Space – is planned for November 7.

Boeing 702 Digital Satellite to Boost Connectivity for Intelsat Customers

Intelsat 37e designed to adapt to surges in connectivity needs

Boeing has 100 percent satellite launch success rate this year
 

EL SEGUNDO, Calif., Sept. 29, 2017 – Boeing [NYSE: BA] has successfully supported seven out of seven satellite launches this year, including today’s launch of a 702 high-throughput digital payload satellite, built for Intelsat.

Intelsat 37e sent and received its first signals from space shortly after it launched today on board an Arianespace Ariane 5 rocket. Once in service, the satellite will deliver high-throughput services to support enterprise, broadband, government and mobility applications in the Americas, Africa and Europe.

“This latest launch is an example of our emphasis on quality and reliability to deliver the right products and capabilities to our customers,” said Paul Rusnock, chairman and CEO, Boeing Satellite Systems International, Inc. “Boeing’s market-leading digital payload technology gives our customers the flexibility to adapt to surges in demand for connectivity when and where it is needed, as well as adapt to any changes in their business needs or missions.”

Intelsat 37e is the second Intelsat EpicNG satellite built by Boeing to launch this year and the fourth Intelsat EpicNG satellite built by Boeing. Intelsat 35e, which launched in July 2017 from Cape Canaveral Air Force Base, Fla., was handed over to the customer last month.

SSL-built direct broadcasting satellite for B-SAT begins post-launch
maneuvers according to plan

Palo Alto, Calif. – SSL, a leading provider of innovative satellites and spacecraft systems, today announced that the BSAT-4a satellite, designed and built for Broadcasting Satellite System Corporation (B-SAT), a leading broadcast satellite operator in Japan, was launched on Friday and is successfully performing post-launch maneuvers according to plan. The satellite deployed its solar arrays on schedule following its launch aboard an Ariane 5 launch vehicle from the European Spaceport in Kourou, French Guiana and it has begun firing its main thruster to propel toward its final geostationary orbit. The satellite will be used for Direct-to-Home (DTH) television service in Japan.

“SSL would like to thank B-SAT, for placing its trust in our ability to provide a highly optimized satellite that will serve the demand for next-generation services in Japan,” said Dario Zamarian, group president of SSL. “It has been a pleasure to work together with the B-SAT and Arianespace teams on this launch, which marks our first satellite for B-SAT and our fourth satellite for the Japanese market in recent years. We look forward to many more opportunities to help B-SAT maintain and expand its fleet.”

SSL is providing B-SAT with delivery-on-orbit service and is on track for early hand over. The satellite is a high-performance broadcasting satellite equipped with 24 Ku-band transponders. From its location at 110 degrees East Longitude, it will expand the availability of advanced television services such as high definition and 4K/8K ultra-high definition.

“We are very pleased that SSL expects to deliver BSAT-4a on-orbit ahead of schedule,” said Takashi Yabashi, president and chief executive officer of B-SAT. “SSL is an innovative and reliable partner that incorporates advanced manufacturing practices that streamline production. With this satellite, we will now be able to provide viewers all over Japan with high definition and 4K/8K ultra-high definition broadcasting for the highest quality direct-to-home service.”

B-SAT plans to use the satellite to provide 4K/8K broadcasting for the Tokyo Olympics and Paralympic games in 2020. The satellite is based on the highly reliable SSL 1300 platform, which provides the flexibility to support a broad range of applications and technology advances. It is designed to provide service for 15 years or longer.
