Indian scientists and researchers at ISRO are working hard in developing India's own Navigation System. They are doing so by setting up a set/constellation of SEVEN satellites, collectively known as Indian Regional Navigation Satellite System (IRNSS). The satellites are named as; IRNSS-1A , IRNSS-1B/ 1C/ 1D/ 1E/ 1F/ 1G.
The 1st satellite (IRNSS-1A) was launched on 1st of July, 2013, aboard the PSLV-C22 rocket.
Recently the 2nd satellite (IRNSS-1B) was launched on 4th of April, 2014, aboard the PSLV-C24 rocket from Satish Dhawan Space Centre, Sriharikota.

The IRNSS constellation will consist of 3 satellites in Geostationary Orbit and the other 4 in Geosynchronous Orbit. The system is designed to be compatible with the US Global Positioning System and Europe's upcoming Galileo constellation using navigation signals in S-Band and at L5. The deployed constellation will only cover India and surrounding regions.
In 2014 itself, TWO more navigational satellites - (IRNSS-1C and IRNSS-1D) would be launched. THREE more navigational satellites - (IRNSS-1E, IRNSS-1F and IRNSS-1G) will be launched early 2015 and by middle of 2015.
