INSAT
Insat (Indian National Satellite System) was a multipurpose satellite system for telecommunications, broadcasting, meteorology and search and rescue services.

Commissioned in 1983, Insat was the largest domestic communication system in the Asia-Pacific Region, and was a joint venture of the Indian Department of Space (DOS), Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. As of 2004 the Insat space segment consisted of: Insat-1D, last of the Insat-1 series launched in 1990; three ISRO-built satellites, Insat-2A launched in July 1992, Insat-2B launched in July 1993 and Insat-2C launched on December 7, 1995; Insat-2DT acquired from Arabsat; Insat-2E launched on April 3,1999; Insat-3B launched on March 22nd 2000; Insat-3C launched on January 24th 2002; Insat-3A launched on April 10th 2003; Insat-3E launched on September 28th 2003; and Gsat-2 and Gsat-3. As of mid-2004 ISRO leased eleven 36 MHz equivalent units of C-band capacity on board Insat-2E to Intelsat.

INSAT system
The Indian National Satellite (INSAT) system was commissioned with the launch of INSAT-1B in August 1983 (INSAT-1A, the first satellite was launched in April 1982 but could not fulfill the mission).
INSAT system ushered in a revolution in India’s television and radio broadcasting, telecommunications and meteorological sectors. It enabled the rapid expansion of TV and modern telecommunication facilities to even the remote areas and off-shore islands. Today, INSAT has become the largest domestic communication satellite system in the Asia-Pacific region with ten satellites in service—INSAT-2E, INSAT-3A, INSAT-3B, INSAT-3C, INSAT-3E, KALPANA-1, GSAT-2, EDUSAT, INSAT-4A and INSAT-4B.

Together, the system provides 199 transponders in C, Extended C and Ku bands for a variety of communication services. Some of the INSATs also carry instruments for meteorological observation and data relay for providing meteorological services. KALPANA-1 is an exclusive meteorological satellite. The satellites are monitored and controlled by Master Control Facilities that exist in Hassan and Bhopal.
