India to have own satellite navigation system by 2015

The Indian Navigation System (INS) satellites would provide coverage over India's areas of interest for military purposes along with its civilian uses, IAF sources told PTI here.

Till now, India is dependent on the American GPS and has signed a deal with Russia for using their GLONAS system but having an indigenous system would guarantee the availability of system during crisis or conflicts.

Asked about similar developments in the neighbourhood, they said China was developing its own version of the GPS which will cover the whole globe.

"But we don't want to cover the whole world and want to focus on the region important for us," the sources said.

The system is also likely to be used for other purposes like telecommunications, transport, identifying disaster areas and public safety among others.

The satellites will be placed at a higher geostationary orbit to have a larger signal footprint and lower number of satellites to map the region, they said.

The GPS system is available for civilian uses only.
