Satellite Navigation System
Four of the seven satellites in IRNSS constellation (IRNSS-1A, 1B, 1C, and 1D) are in orbit. Remaining three satellites (IRNSS-1E, 1F and 1G) are targeted for launch during January 2016 to March 2016.
Self reliance in the strategically important area of position related information will be achieved with the use of indigenously built constellation of seven IRNSS satellites and a network of required ground segment.
The IRNSS constellation is planned to be completed by March 31, 2016. By design, the service area of IRNSS constellation encompasses the SAARC countries. Like GPS, the Standard Positioning Services of IRNSS is made available to all the users. The SAARC member countries, therefore, can adopt the IRNSS system for the navigational services.
