HYLAS (or HYLAS-1) is a British satellite in geostationary orbit. HYLAS, which is an acronym for Highly Adaptable Satellite, is a communications satellite and was launched by the European Ariane 5 launch vehicle from the Guyana Space Centre at Kourou in French Guiana.The Hindu - November 27, 2010 -ISRO's communication satellite HYLAS launched successfully [http://www.thehindu.com/sci-tech/technology/article917421.ece?homepage=true] It is located at the orbital location of 33.5 degrees west and will provide new and innovative services including High Definition Television (HDTV) and interactive satellite delivered broadband services.{{cite web |url=http://www.lyngsat.com/launches/ka.html |title=Ka Band Launches (as seen 6th Sept. 2010) |author=S Günes 100827 |publisher=Lyngsat}}

Construction
HYLAS was constructed by EADS Astrium for the UK telecommunications company Avanti Communications Plc. Development of the satellite was supported by a £23m investment from the British National Space Centre (BNSC).{{cite web |url=http://www.bnsc.gov.uk/content.aspx?nid=5920 |title=BNSC - Avanti |access-date=2007-10-08 |url-status=dead |archive-url=https://web.archive.org/web/20070628184221/http://www.bnsc.gov.uk/content.aspx?nid=5920 |archive-date=2007-06-28 }} BNSC case study on Avanti and the HYLAS satellite
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.{{cite web |url=http://www.spacex.com/updates_archive.php?page=121007 |title=Updates Archive - New Customer |publisher=SpaceX |date=2007-12-10 |access-date=2008-08-08 |archive-date=2013-04-05 |archive-url=https://web.archive.org/web/20130405083840/http://www.spacex.com/updates_archive.php?page=121007 |url-status=dead }} In July 2009 Arianespace announced that HYLAS would instead be launched in 2010, "using an Ariane 5 or Soyuz launcher" from Arianespace.{{cite web |url=http://www.arianespace.com/news-press-release/2009/07-22-09-Hylas-contract.asp |title=Arianespace to launch HYLAS |date=July 22, 2009 |publisher=Arianespace |url-status=dead |archive-url=https://web.archive.org/web/20090726094741/http://www.arianespace.com/news-press-release/2009/07-22-09-Hylas-contract.asp |archive-date=July 26, 2009 }}{{cite web |url=http://news.bbc.co.uk/2/hi/science/nature/8164236.stm |title=Broadband satellite jumps rocket |author=Jonathan Amos |publisher=BBC | date=July 23, 2009 | access-date=January 5, 2010}} 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.{{cite web |url=http://www.space.com/news/090713-busmon-spacex-customer.html |title=Satellite Firm Raises $68 Million in Cash to Switch Rockets |author=Peter B. de Selding |date=13 July 2009 |publisher=Space News}}
HYLAS successfully launched at 18:41 GMT on the 26 November 2010 by Ariane 5.
Mission
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.{{cite web |url=http://www.satnews.com/stories2006/2635.htm |title=Your Daily Briefing of Satellite |access-date=2007-10-08 |url-status=dead |archive-url=https://web.archive.org/web/20071030145942/http://www.satnews.com/stories2006/2635.htm |archive-date=2007-10-30 }} SatNews Daily report on HYLAS
The HYLAS payload carries 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 had a launch mass of around 2100 kg and a beginning-of-life power of 3.5 kW.http://www.esa.int/esaTE/SEMAB09ATME_index_0.html ESA News
Orbital position
The orbital position of HYLAS was adjusted to 18.3° West Longitude during June 2019.
