Intelsat 37e Preparing for Launch

Press Release
 
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.

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.

L592 through L599 apparently assigned to Ariane 5 ES.  L592 flew in 2013.
