Launch and Arabsat service

Launched in 1992 as Arabsat-1C, it was operated at 31° East longitude in geostationary orbit, [2] 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 1,170 kilograms (2,580 lb), and an expected operational lifespan of seven years. [1]

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 operations

In 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]
