INSAT-1C was the third in the first generation INSAT series of satellites(termed as INSAT-1) developed by United States to satisfy the domestic communication requirement of India. The Govt. agencies using its services were All India Radio, Doordarshan, Department of Space and Indian Meteorological Department[1]

Launch[edit]

INSAT-1C was launched from Guiana Space Centre in Kourou using Ariane 3 rocket on July 21st, 1988.At launch, it had a mass of 1,190 kilograms (2,620 lb), and an expected operational lifespan of seven years.The satellite was positioned at 93.5° East longitude in geostationary orbit

Payloads[edit]

INSAT-1C carried 3 payloads on board to provide communication services to Indian Meteorological Department, Department of Telecommunications and Department of Space:

  • Very High Resolution scanning Radiometer (VHRR)
  • 12 transponders operating in 2-phases(earth-to-satellite and vice-versa).
  • Data channel to send data for land based applications.[2]

Mission[edit]

INSAT-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]
