India completed its landmark mission for a regional navigational system on par with US-based GPS with the successful launch of IRNSS-1G, the seventh and last in the constellation of satellites that make up the system on Thursday.
Take a look at some pictures taken during the build and transport phase of the satellite.
Till date, India has launched six regional navigational satellites (IRNSS-1A, 1B, 1C, ID,1E and 1F) as part of a constellation of seven satellites to provide accurate position information service to users across the country and the region, extending up to an area of 1,500 km.
Though the full system comprises nine satellites -- seven in orbit and two on the ground as stand-by, the navigation services could be made operational with four satellites, ISRO officials had said earlier.
The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014, the fourth in March 2015, and the fifth and sixth on January 20 and March 10, 2016.
According to ISRO the applications of IRNSS are: terrestrial, aerial and marine navigation, vehicle tracking and fleet management, terrestrial navigation for hikers and travellers, disaster management, integration with mobile phones, mapping and geodetic data capture and visual and voice navigation for drivers.
The satellite with a design life span of 12 years has two payloads for navigation and ranging.
According to ISRO, with the operationalisation of six IRNSS satellites, the proof of concept of an independent regional navigation satellite system over India has been demonstrated for the targeted position accuracy of better than 20 metres over 24 hours of the day.
