Template:Infobox Spacecraft HYLAS, an acronym for Highly Adaptable Satellite, is the name of a small geostationary communications satellite planned for launch in late 2010 or early 2011. It will be at 33.5W [1]for Western Edge of Europe, Mainly UK and Ireland.

HYLAS is being constructed by EADS Astrium for the UK telecommunications company Avanti Communications Plc. Development of the satellite is being supported by a £23m investment from the British National Space Centre (BNSC).[2]

HYLAS is based on the Indian Space Research Organisation's I-2K small satellite platform under a cooperative arrangement between EADS Astrium and ISRO/Antrix[3].

The HYLAS payload will carry two Ku-band transponders, intended mainly for HDTV, and six Ka-band transponders feeding up to eight Spotbeams, allowing the provision of between 150,000 and 300,000 simultaneous broadband Internet connections. The HYLAS satellite will have a launch mass of around 2100 kg and a beginning-of-life power of 3.5 kW[4].

Launch

Avanti purchased for HYLAS a launch to geostationary transfer orbit (GTO) on a Falcon 9 launch vehicle. The purchase, in September 2007, made Avanti the first customer to purchase a commercial geostationary launch from SpaceX.[5] In July 2009 Arianespace announced that HYLAS would instead be launched in 2010, "using an Ariane 5 or Soyuz launcher" from Arianespace.[6][7] Avanti had previously criticized Arianespace as being overly expensive, but a move to Arianespace was motivated by prospective customers' concerns about launch risks associated with Falcon 9. Also, additional financial assets became available, including 10.7 million pounds from British contributions ESA's Artes telecommunications development program.[8]
