6 things to know about India\'s own GPS system
ISRO has successfully launched IRNSS-1G, the last in the series of seven navigation satellites. PSLV-C33 (Polar Satellite Launch Vehicle) placed the satellite in orbit.
With this launch, India does not have to depend on another nation for military navigation.
Here are 6 things you need to know about India's big navigation leap:
The Indian Regional Navigation Satellite System comprising seven satellites would be able to provide navigation system with much better accuracy and targeted position.
It is designed to provide accurate real-time positioning and timing services over India and region extending to 1,500 km around India.
The system will be very much similar to the GPS of the US which has 24 satellites, Glonass of Russia (24 satellites), Galileo of Europe (27 satellites) and China's Beidou (35 satellites).
The system will be used for terrestrial, aerial and marine navigation, disaster management, vehicle tracking and fleet management, integration with mobile phones, precise timing, mapping and geodetic data capture, terrestrial navigation aid for hikers and travellers, visual and voice navigation for drivers.
ISRO launched sixth navigation satellite IRNSS-1F on March 10, the other five being IRNSS-1A on July 1, 2013, IRNSS-1B (April 4, 2014), IRNSS-1C (October 16, 2014), IRNSS-1D (March 28, 2015) and IRNSS-1E (January 20, 2016).
According to Isro officials, total cost of all the seven satellites was Rs 1,420 crore and it has a 12-year mission life.
