'''INSAT-2DT''', previously '''Arabsat-1C''' and also known as '''INSAT-2R''', was a [[Saudi Arabia]]n and subsequently [[India]]n [[communications satellite]] which was operated initially by [[Arab Satellite Communications Organization|Arabsat]], and then by the [[Indian National Satellite System]].

==Launch and Arabsat service==
Launched in 1992 as Arabsat-1C, it was operated at 31° East [[longitude]] in [[geostationary orbit]],<ref name="EA">{{cite web |url=http://www.astronautix.com/project/arabsat.htm |title=Arabsat |last=Wade |first=Mark |publisher=Encyclopedia Astronautica |access-date=2009-07-05 |url-status=dead |archive-url=https://web.archive.org/web/20090331213805/http://www.astronautix.com/project/arabsat.htm |archive-date=2009-03-31 }}</ref> from where it was used to provide communication services to the [[Arab States]]. It was constructed by [[Aérospatiale]], based on the [[Spacebus 100]] [[satellite bus]], and carried two NATO E/F-band (IEEE S band) and 25 NATO G/H-Band (IEEE C band) [[transponder]]s. At launch, it had a mass of {{convert|1170|kg}}, and an expected operational lifespan of seven years.<ref name="GSP">{{cite web |url=http://space.skyrocket.de/doc_sdat/arabsat-1a.htm |title=Arabsat 1A, 1B, 1C / Insat 2DT |last=Krebs |first=Gunter |publisher=Gunter's Space Page |access-date=2009-07-05}}</ref>

It was launched by [[Arianespace]] using an [[Ariane 4]] rocket in the 44L configuration, flying from [[ELA-2]] at the [[Guiana Space Centre]] in [[Kourou]]. The launch took place at 22:58:10 UTC on 26 February 1992.<ref name="JSR-LL">{{cite web |url=http://planet4589.org/space/log/launchlog.txt |title=Launch Log |last=McDowell |first=Jonathan |publisher=Jonathan's Space Page |access-date=2009-07-05}}</ref> It was the final [[Spacebus 100]] satellite to be launched.

==Indian operations==
In November 1997, Arabsat-1C was sold to India as INSAT-2DT.<ref name="TSE-1C">{{cite web |url=http://www.tbs-satellite.com/tse/online/sat_arabsat_1c.html |title=Arabsat 1C |publisher=TSE |access-date=2009-07-05}}</ref> In December, it was moved to a new slot at 55°E longitude, where it replaced the [[INSAT-2D]] satellite which had failed in orbit.<ref name="TSE-2D">{{cite web |url=http://www.tbs-satellite.com/tse/online/sat_insat_2d.html |title=INSAT-2D |publisher=TSE |access-date=2009-07-05}}</ref> It remained at 55°E until August 2003, when it was moved to 85.2°E, arriving in November.<ref name="TSE-2DT">{{cite web |url=http://www.tbs-satellite.com/tse/online/sat_insat_2r.html |title=INSAT-2R |publisher=TSE |access-date=2009-07-05}}</ref> By the time of its departure from 55°E, its orbital [[inclination]] had increased somewhat.

INSAT-2DT remained at 85.2°E until October 2004, when it was retired from service and placed into a [[graveyard orbit]].<ref name="TSE-2DT"/>
