Indian Regional Navigation Satellite System Adds Final Navigational Satellite in Space

The Indian Space Research Organization (ISRO) launched its seventh and final navigational satellite from the "Satish Dahawan Space Center" located in Sriharikota. These launches began in 2013 and finally ended on April 28, 2016.

The Indian government run space agency is headquartered in Bangalore was established in 1969. They remain true to their vision of harnessing space technology for national development, while pursuing space science research and planetary exploration.

The Indian Space Research Organization (ISRO) launched all previous satellites at separate times and have reached their designated orbital positions.

  • The first navigation satellite IRNSS-1A was launched back in July 2013 and cost $19 million.
  • The second satellite, IRNSS1B was officially placed in its orbit in April 2014.
  • The third satellite, IRNSS-1C was successfully launched and placed October 2014
  • The fourth navigation satellite, IRNSS-1D was launched in March 2015
  • The fifth navigation satellite, IRNSS-1E was successfully launched in January 2016
  • The sixth navigation satellite, IRNSS-1F reached its orbital point in March 2016

The final flight, IRNSS-1G lasted only 19 mins and 42 seconds, at an angle of 17.867 degrees towards the world’s equator. While in space, there will be four orbital maneuvers that will position the satellite at its geostationary coordinate, 129.5 degree East longitude.

The IRNSS-1G will not be operational for another few weeks before reaching its final destination. The Indian Space Research Organization plans to use these satellites for GPS Standard Positioning Services and Restricted Services.
