Lets See What is NAVIC and its Origin
Navigation with Indian Constellation- NAVIC (ISRO); It is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It not only covers India but also region extending 1,500 km or 930 miles around it, with plans for further extension.Currently the system consists of a constellation of seven satellites with two additional satellites on ground as stand-by. As of 2018; the constellation is in orbit and the system was expected to be operational from early 2018 after a through system check. Navic provides two levels of service – standard positioning service; which will be open for civilian use and second one a restricted service (encrypted) one for authorised users (which includes Indian Armed Forces). The system was developed by Bharat because being reliable upon foreign government-controlled global navigation satellite systems is always risky and not guaranteed in hostile situations, as in 1999 during kargil war; United States of America denied the Indian request for Global Positioning System, GPS; data for the Kargil region which would have provided vital information to combat enemeies more efficiently with very minimum casualities. This incident made Indian government to look for its own GPS project in May 2013.
Development of Navic Project
As a project, an Indian Space Research Organisation also called ISRO opened a New satellite navigation centre at the campus of ISRO-Deep Space Network called as DSN in Karnataka at Byalalu on 28 May 2013. A group of of 21 ranging stations situated across India will provide data of orbital determination of the satellites and monitoring of the navigation signal.As per Aatma nirbhar Bharat initiative which aims at complete Indian control with the space segment, ground segment and user receivers all being built in India. Its the location which is in low latitudes will facilitate a coverage with low-inclination satellites. Three satellites are in geostationary orbit over the Indian Ocean. One of its main purpose is Missile targeting could be game changer and an important military application for the constellation.The estimated total cost of the project is expected to be 14.2 billion (US$199 million), which involves the cost of the ground segment being 3 billion (US$42 million),however each satellite costing 1.5 billion (US$21 million) and the PSLV-XL version rocket costing around 1.3 billion (US$18 million). The planned seven rockets would have involved an outlay of around costing 9.1 billion (US$128 million).
The two replacement satellites and PSLV-XL launches, has altered the original budget, with the Comptroller and Auditor General of India reporting costs 22.46 billion (US$315 million). The Navic signal was for evaluated in September 2014.Use of AIS-140 compliant NavIC-based vehicle tracking systems were made compulsory From 1 April 2019 for all commercial vehicles in India.Qualcomm has launched three new chipsets, Snapdragon 720G, 662 and 460 with support for Navigation in January 2020 with Indian Constellation (NavIC). Navic is planned to be available for common man use in mobile devices, after Qualcomm and Indian Space Research Organisation, ISRO signed an agreement.
