Indian National Satellite System (INSAT) is a series of multipurpose satellites launched by ISRO for telecommunications, broadcasting, meteorology, and search and rescue services. Commissioned in 1983, INSAT was the largest domestic communication system in the Asia-Pacific Region. It comprises the following satellites - INSAT-2DT, INSAT-2E, INSAT-3A, INSAT-3B, INSAT-3C, INSAT-3E, KALPANA-1, GSAT-2 and METSAT. INSAT-2DT was acquired from Arabsat because of failure of INSAT-2D
INSAT satellites provide transponders (about 120) in various bands (C, S, Extended C and Ku). Some of the satellites also have Very High Resolution Radiometer (VHRR) and CCDcameras for metrological imaging. These satellites also incorporates a transponder for receiving distress alert signals for search and rescue missions as ISRO is part of the COSPAS/SARSAT Programme for Search and Rescue.
Between 1982 and 1990 four U.S.-built INSAT 1 satellites were launched to support Indian domestic communications and Earth observation requirements as a joint venture among the Indian Department of Space, the Department of Telecommunications, the Meteorological Department, All-India Radio, and All India Doorarshan Television.
INSAT 1 D (June, 1990) was operational at 83 degrees E. The INSAT 2 program was underway in 1983 to develop an indigenous multi-purpose GEO spacecraft that relied heavily on the previous Ford Aerospace design.
INSAT 2B was launched 22 July 1993 by an Ariane rocket and positioned at 93.5 degrees E. In March, 1994, India selected Arianespace to launch INSATs 2C and 2D in 1995 and 1996, respectively.
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.
In geostationary orbit the satellite was to be co-located with Kalpana-1 and Insat-3C satellites at 74 deg East longitude.
