India is on the way to its own GPS.The country today(28 March,2015) launched satellite IRNSS-1D from Sriharikota onboard PSLV-C27 to pave the way for the country’s own navigation system on par with the GPS of US.
The satellite was launched from the Satish Dhawan Space Centre at Sriharikota.
IRNSS-1D is the fourth in the series of seven satellites, planned by ISRO to put in place the Indian Regional Navigation Satellite System (IRNSS).The IRNSS system will be focussed at South Asia and is designed to provide accurate position information services to users in the country, as well as the region extending up to 1,500 km from its boundary.
IRNSS’ applications include terrestrial and marine navigation, disaster management, vehicle tracking and fleet management, navigation help for hikers and travellers, visual and voice navigation for drivers in the region.
In this type of navigation system four satellites would be sufficient to start operations of the system, the remaining three would make it more accurate and efficient.
The previous three satellites in the IRNSS series were launched from Sriharikota on July 1, 2013, April 4 and October 16 last year.
