Flight VA239: Arianespace to launch INTELSAT 37e and BSAT-4a on September 5, 2017, with Ariane 5



For its ninth launch of the year, and the fifth Ariane 5 mission in 2017 from the Guiana Space Center in French Guiana, Arianespace will orbit Intelsat 37e for the operator Intelsat and BSAT-4a for the manufacturer SSL (Space Systems Loral) in the framework of a turnkey contract for the Japanese operator Broadcasting Satellite System Corporation (B-SAT).
                        
With this 292th mission performed by its family of launchers, and the 239th utilizing an Ariane family launch vehicle – Arianespace is at the service of the latest innovation in space telecommunications.
The Launch Readiness Review (LRR) will take place on Friday, September 1, 2017 in Kourou, to authorize the start of operations for the final countdown.

Intelsat 37e is 59e Intelsat's satellite to be launched by Arianespace since the successful orbiting of Intelsat 507 in October 1983. It also is the fifth broadband infrastructure satellite in the Intelsat EpicNG series and the fourth EpicNG spacecraft orbited by Arianespace to date, a sign of Intelsat's great confidence in Arianespace launch services.

Intelsat 37e represents a significant evolution of the award-winning EpicNG platform, incorporating enhanced power sharing technology, which enables the assignment of power between shaped, fixed and steerable spot Ku-band and Ka-band beams. This allows optimized services to meet the requirements of in-demand applications – by region – and the delivery of higher transmission efficiency for mobility and government customers in the Americas, Africa and Europe.

Intelsat 37e is the first satellite to offer interconnectivity between three different bands. This next-generation spacecraft delivers high-performance service in C-, Ku- and Ka-bands for use in wireless backhaul, enterprise VSAT and mobility networks.

Built by Boeing based on its 702MP platform, Intelsat 37e will be the 55th satellite made by this manufacturer to be launched by Arianespace.

The BSAT-4a satellite, designed and built for B-SAT, a leading broadcasting satellite operator in Japan, will be used for Direct-to-Home (DTH) television service across the Japanese archipelago. BSAT-4a is the 9th satellite to be launched by Arianespace for B-SAT, and is being orbited as part of a turnkey contract between B-SAT and the U.S.-based satellite manufacturer SSL.

The BSAT-4a satellite has 24 Ku-band transponders and will expand the availability of advanced television services such as high definition and 4K/8K ultra-high definition.

The satellite is based on the highly-reliable SSL 1300 platform, which provides the flexibility to support a broad range of applications and technological advances. BSAT-4a will be the 64nd SSL-built satellite made by this manufacturer to be launched by Arianespace.

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


The completion of Ariane 5's assembly for Flight VA239 is shown during activity in the Spaceport's Final Assembly Building. At left, BSAT-4a is positioned atop the launcher, followed by the installation of Intelsat 37e (center and right), which is encapsulated in a long version of Ariane 5's payload fairing.

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).

ЦитироватьIntelsat 37e Preparing for Launch

Fifth Intelsat EpicNG satellite will be launched by Arianespace on September 5

Luxembourg, 30 August 2017
Intelsat S.A. (NYSE:I), operator of the world's first Globalized Network and leader in integrated satellite communications is preparing for the launch of Intelsat 37e, the fifth in their next-generation of high throughput satellites. The high performance satellite will be launched by Arianespace on an Ariane 5 launch vehicle on September 5, 2017 at 5:51 pm EDT at the Guiana Space Center in Kourou, French Guiana.

Manufactured by Boeing, the all-digital Intelsat 37e payload represents a significant evolution of the award-winning Intelsat EpicNG platform.  The satellite features full beam interconnectivity in the C, Ku- and Ka-bands, and also includes enhanced power sharing technology and steerable beams in Ku- and Ka-band.  These features combine to bring additional flexibility to address regional and application requirements for broadband, mobility and government customers in the Americas, Africa and Europe. Intelsat 37e will be placed into service at 342° East where it replaces Intelsat 901, which will be repositioned to another location in Intelsat's Globalized Network.

A live webcast of the launch will be available here.
