Insat 2C, 2D

Insat 2C [ISRO]

In March, 1994, India selected Arianespace to launch Insats 2C and 2D in 1995 and 1996, respectively. The design lifetime was nine years. The spacecraft are similar to the earlier Insats but are 200 kg heavier at launch (2,100 kg) and carried larger solar arrays for 1.6 kW of electrical power. The communications payload consisted of 12 C-band, 6 extended C-band, 3 Ku-band, and 2 S-band transponders plus a new low-power C-band transponder for a mobile communicatins feeder. Insat-2C and Insat-2D, in addition to carrying communication transponders in Insat-2A and 2B, incorporated Ku-band transponders for business communication, extended coverage C-band transponders to enable TV programme outreach beyond Indian boundaries catering to the population from South East Asia to the Middle East and transponders for mobile service. They did not have the meteorological payload. Insat-2C and Insat-2B were co-located in the geostationary orbit thus enabling efficient use of allocated orbital slots.
