NAVIC: Trending India’s own GPS system

Sivasagar, Prangan Duarah: Indian Space Research Organization (ISRO) continues to ramp up its space activities, which include a new launch of the seventh and final satellite to create India’s own satellite-navigation system. On 28th April, a 44.4-meter tall PSLV rocket, weighting 320 tonnes, blast into the clear sky of India and after a few minutes, the people of India got the good news that it successfully launched the satellite IRNSS-G1, which liberates Indian GPS system from dependence on US and Russia. It is launched from the Sri Hari Kota of Andhra-Pradesh. As announced by Narendra Modi, the prime- minister of India, Indian GPS system is officially named as Indian Regional Navigation Satellite System (IRNSS) or Navigation with Indian Constellation (NAVIC), which consist of a total of 9 satellites. Seven in the orbit and two on the ground as stand-by. Amongst the seven satellites three of these satellites will be geostationary over the Indian Ocean, i.e., they will appear to be stationary in the sky over the region, and four will be geosynchronous – appearing at the same point in the sky at the same time every day. It is estimated that the average lifespan of IRNSS satellites is about 9.5 years for geostationary and about 11 years for geosynchronous.

According to the source the system is designed to provide accurate position information to users in India and as far as 1,500 kilometers (932 miles) from its borders and a less accurate extended service area would cover the region enclosed by latitude 30º south to 50º north, longitude 30º east to 130º east. The satellites will be able to track the location and position of vehicles, provide information during natural disasters and integrated with mobile phones for navigation and other location services.

According to the source the system will be also useful for terrestrial and marine navigation, disaster management, integration with mobile phone, precise timing, mapping, geodetic data collection, terrestrial navigational aid for hikers and travelers, visual and voice navigation for drivers etc. According to Indian Space Research Organization, the system will provide two kinds of services: one which is open source and another which is restricted and strongly encrypted, provided only to “authorize users”. ISRO starts this mission on 1st July 2013 by launching its first navigational satellite IRNSS-1A, second satellite IRNSS-1B was launched on 4th April 2014, third satellite IRNSS-1C was launched on 16th October 2014, fourth satellite IRNSS-1D on 28th march 2015, fifth satellite IRNSS-1E on 20th January 2016 and the sixth satellite IRNSS-1F on 10th march 2016. According to the ISRO, the total cost of all the satellites was Rs. 1420 Crore. Each satellite costs about Rs 150 Crore and each PSLV-XL rocket costs about Rs 130 Crore. Now India is ready to use its very own GPS navigation system. One more story of success is added to the history of ISRO which liberates India from dependence on US and Russia.
