'''INSAT-1C''' was the third in the first generation INSAT series of satellites (termed as INSAT-1) built by [[Ford Aerospace]] 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]]<ref>{{cite web | url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1988-063A | title=INSAT 1C | publisher=NASA | access-date=2013-04-10}}</ref>

==Launch==
INSAT-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]]

==Payloads==
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.<ref>{{cite web | url=http://isrohq.vssc.gov.in/isr0dem0v2/index.php/rti/40-satellites-details/200-insat-1c | title=INSAT-1C | publisher=Vikram Sarabhai Space Centre | access-date=2013-04-10 | archive-url=https://archive.today/20130705153705/http://isrohq.vssc.gov.in/isr0dem0v2/index.php/rti/40-satellites-details/200-insat-1c | archive-date=2013-07-05 | url-status=dead }}</ref>

==Mission==
INSAT-1C mission was a success and lasted for about 13 years because the satellite got another 6 C-band transponders and 2 S-band transponders when a power system made one
