INSAT-2D was an Indian communications satellite. Launched on 4 June, 1997, and similar to INSAT-2C, INSAT-2D went out of order on October 4, 1997 because of a power inconsistency problem and was later replaced by INSAT-2DT, an in-orbit satellite which was previously known as ARABSAT-1C. The main aim of the satellite was the betterment in the communication. In the INSAT-2 (Indian National Satellite System) series, INSAT-2D was the fourth consecutive communication satellite. The satellite was launched using an Ariane 4 rocket from French Guiana.
The satellite was placed into Geo-stationary orbit at an inclination of 93.5 degree East. The lift off mass of the satellite Insat-2D was 2,079 kg (4,583 lb) with propellants of which 995 kg (2,194 lb) were the dry weight. The satellite was expected to have a nominal lifespan of around 7-9 years. The onboard power of the satellite was estimated to be 1650 Watts.
Its communication payload consisted of transponders of 16C-band / extended C-band transponders (forFSS), two high power C-band transponders (for BSS), 1S-band transponder (for BSS), 1C/S-band mobile communication transponder, and three Ku-band transponders.
