The Govt. agencies using its services were All India Radio, Doordarshan, Department of Space and Indian Meteorological Department[1] LaunchINSAT-1C was launched from Guiana Space Centre in Kourou using Ariane 3 rocket on July 21, 1988. At launch, it had a mass of {{convert|1190|kg}}, and an expected operational lifespan of seven years. The satellite was positioned at 93.5° East longitude in geostationary orbit PayloadsINSAT-1C carried 3 payloads on board to provide communication services to Indian Meteorological Department, Department of Telecommunications and Department of Space:
MissionINSAT-1C mission was a failure and lasted only for about 1.3 years because the satellite lost its 6 C-band transponders and 2 S-band transponders when a power system failure knocked out one of the two buses[3][4] See also{{Portal|Spaceflight}}
