Launch and Arabsat serviceLaunched in 1992 as Arabsat-1C, it was operated at 31° East longitude in geostationary orbit,[1] 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) transponders. At launch, it had a mass of {{convert|1170|kg}}, and an expected operational lifespan of seven years.[2] 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.[3] It was the final Spacebus 100 satellite to be launched. Indian operationsIn November 1997, Arabsat-1C was sold to India as INSAT-2DT.[4] 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.[5] It remained at 55°E until August 2003, when it was moved to 85.2°E, arriving in November.[6] 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.[6] See also{{Portal|Spaceflight}}
