India gets its own GPS called NAVIC
India’s Regional Navigation Satellite System i.e IRNSS-1G will be known to the world as, NAVIC that is used to provide accurate real-time positioning and timing services over India and region extending to 1500 km around India .The fully deployed NAVIC system contains of 3 satellites in GEO orbit( geostationary orbit, geostationary Earth orbit or geosynchronous equatorial orbit) and 4 satellites in GSO orbit(geosynchronous orbit), approximately 36,000 km altitude above from earth surface.
Basically The NAVIC would provide two services, with the Standard Positioning Service open for civilian use, and the Restricted Service (an encrypted one) for authorized users (including the military).
India’s Present Prime Minister Narendra Modi congratulated the scientists involved in the mission of NAVIC saying
”With this successful launch of IRNSS-1G, we shall determine our own paths powered by our technology, which gave new Era to the world. The world will come to know it as NAVIC…. and it will surely benefit our people, especially fishermen. This will be a great gift to people from scientists:”
NAVIC will featuring services terrestrial and marine navigation,vehicle tracking, disaster management, navigation aide for hikers and travellers and fleet management,visual and voice navigation for drivers.
Till now , We have already launched 6 regional navigational satellites includes IRNSS-1A,, 1C, 1B, ID, 1F ,1E and “IRNSS-1G, the 7th and LAST in satellite of the system.
The full system of NAVIC combined of nine satellites – seven satellites in orbit and two on the ground as stand-by condition.
IRNSS-1A was launched in JUL 2013, the 2nd in IRNSS-1B in APR 2014, the 3rd on OCT 2014, the 4th in MAR 2015, and the fifth and 6th on JAN 20 and MAR 2016.
Each satellite costs all about 150 crore(Rupees), and PSLV-XL rocket costs about 130 crore (rupees).and seven rockets would fetch cost about Rs.910 crore.
The final total cost including all other type of facilities is about 1,420 crore(rupees)..
