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 fulfil the mission). INSAT system ushered in a revolution in India's television and radio broadcasting, telecommunications and meteorological sectors. It enabled the ...
The system was developed partly because access to foreign government-controlled global navigation satellite systems is not guaranteed in hostile situations, as happened to the Indian military in 1999 when the United States denied an Indian request for Global Positioning System (GPS) data for the Kargil region, which would have provided vital information.

The GSAT series of geosynchronous satellites is a system developed by ISRO with an objective to make India self-reliant in broadcasting services. The system includes a total of 168 transponders (out of which 95 are leased out to provide services to broadcasters) in the C, Extended C and K u bands, providing services to telecommunications, television broadcasting, weather forecasting, disaster ...
IRNSS-1 Indian regional navigational satellite system (IRNSS)-1, the first of the seven satellites of the Indian Regional Navigation Satellite System constellation, carries a navigation payload and a C-band ranging transponder. The spacecraft employs an optimised I-1K structure with a power handling capability of around 1660W and a lift off ...
The satellite has been developed at a cost of ₹ 1.25 billion (US$15 million), [3] [4] and was launched on 1 July 2013. It will provide IRNSS services to the Indian public, which would be a system similar to Global Positioning System (GPS) but only for India and the region around it.
IRNSS-1B is the second out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A. [2] The IRNSS constellation of satellites is slated to be launched to provide navigational services to the region. It was placed in geosynchronous orbit on 4 April 2014. [3] [4]
