In the past five decades, ISRO has launched more than 50 satellites for various scientific and technological applications like mobile communications, Direct-to-Home services, meteorological observations, telemedicine, Tele- education, disaster warning, radio networking, search and rescue operations, remote sensing and scientific studies of the space. ISRO has established two major space systems, INSAT for series of communication and Indian Remote Sensing (IRS) for resource monitoring & management.

Geo-Stationary Satellites

A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period. Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma. A special case of geosynchronous satellite is the geostationary satellite, which has a geostationary orbit – a circular geosynchronous orbit directly above the Earth's equator. Another type of geosynchronous orbit used by satellites is the Tundra elliptical orbit.

1. The Indian National Satellite (INSAT) system which is placed in Geo-stationary orbits is one of the largest domestic communication satellite systems in Asia-Pacific region.  It established in 1983 with commissioning of INSAT-1 B, it initiated a major revolution in India's communications sector and sustained the same later.
2. INSAT space segment consists of 21 satellites out of which 11 are in service (INSAT-2E, INSAT-3A, INSAT-3B, INSAT-3C, INSAT-3E, KALPANA-1, GSAT-2, EDUSAT and INSAT 4A, INSAT-4B,INSAT-4CR).
3. The system with a total of about 211 transponders in the C, Extended C and Ku-bands.  It Provides services to telecommunications, television broadcasting, weather forecasting, disaster warning and Search and Rescue operations.

1. Indian Remote Sensing (IRS) satellite system was commissioned with the launch of the first
2. Indigenously built remote sensing satellite IRS-1 A, in 1988.
3. With ten satellites in operation, IRS is the largest civilian remote sensing satellite constellation in the world providing imageries in a variety of spatial resolutions, spectral bands and swaths.
4. The IRS Satellites which are currently in service are OCEANSAT-1, TES, RESOURCESAT-1,
5. CARTOSAT-1, CARTOSAT-2, I MS-1, CARTOSAT- 2A, RISAT-2, OCEANSAT-2 and CARTOSAT-2B
6. The data is used for several applications covering agriculture, water resources, urban development, mineral prospecting, environment, forestry, drought and flood forecasting, ocean resources and disaster management.
