INSAT-2C (also known as Indian National Satellite-2) was an Indian geostationary communications spacecraft.[1][2][3] It is ISRO's third indigenous communications satellite.[4]


It was launched by Ariane 44L from Guiana Space Centre, French Guiana on December 6, 1995.[3][4] It was working properly for years, but in January 2013, its communication C-band transponder collapsed.[5][6] It was launched to improve communication facilities in Northeast India and Andaman and Nicobar Islands.[7]


Its mass during launch was 2,106 kg and dry mass was 946 kg. It revolves around Geostationary orbit with altitude of 35,786 and longitude of 93.5 degree east.[8] Its onboard power was 1,320 Watts with mission life of 7 years and its planned orbit life to be very long.[9]


It has capabilities like business communication, mobile satellite service and can make television outreach beyond boundary of India.[2][10]
