Know About the Indian Version of GPS


The “desi” version of GPS is on its way. Indian Regional Navigation Satellite System (IRNSS) will fulfil India’s navigation dreams by providing information on location and time in any weather conditions.

Here are some facts you may not know about the Indian version of GPS:

  • IRNSS will be composed of seven satellites. Three of them will be in the geostationary orbit. Rest of them will be in inclined geosynchronous orbit. All of them will mainly cover the area around India.


  • As of now, IRNSS consists of just 7 satellites. But, it will be further expanded to 11 satellites in future.

IRNSS 7 satellites

  • Out of the 7 satellites, four has already been launched.  IRNSS-1A, the first navigational satellite was launched on 1 July, 2013. IRNSS-1B, the second satellite was launched on 4 April, 2014.  The third satellite IRNSS-1C was launched on 16 October, 2014. Launch of IRNSS-1D, the fourth satellite, happened on 28 March, 2015.


  • ISRO, the organization that had created history with their Mars Orbiter Mission, is behind the mission.


  • India’s civil aviation sector is going to benefit the most out of its own GPS system. There will be a major difference in the functioning of airports in the country. Also, different types of new satellite based services will be launched.

India’s civil aviation

  • With IRNSS, India will be joining the league of countries that have their own GPS systems. Russia's GPS system is called “Glonass” and that of Europe is called “Galileo”. Also, China and Japan have GPS systems named “Beidou” and Japanese “Quasi Zenith Satellite System” respectively.

GPS systems

  • The applications of IRNSS include terrestrial and marine navigation, disaster management, vehicle tracking and fleet management.
