INSAT-2C

An India-built communication satellite launched in December 1995 that added Ku-band and mobile services and stretched INSAT TV coverage beyond India.

No longer operational, according to the public satellite catalogue.

What it did

INSAT-2C was a communication-only satellite; unlike INSAT-2A and 2B, it had no weather payload. It added Ku-band transponders for business communication and a transponder for mobile communication.

ISRO raised the power of four C-band transponders to improve links to remote areas such as the Northeast and the Andaman and Nicobar Islands. Two other C-band transponders had wider coverage reaching parts of Southeast, Central and West Asia.

Spacecraft

INSAT-2C weighed 2,106 kg with propellant and 946 kg dry, and had 1,320 watts of power. It carried 16 C-band and extended C-band transponders, 2 high-power C-band and 1 S-band broadcasting transponders, 1 C/S-band mobile transponder and 3 Ku-band transponders.

Launch and orbit

An Ariane 4 rocket launched INSAT-2C from Kourou, French Guiana, in December 1995. It was placed in geostationary orbit at 93.5° E, sharing the slot with INSAT-2B. Its design life was seven years.
