Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC (acronym for Navigation with Indian Constellation; also, nāvik 'sailor' or 'navigator' in Indian languages),[2] is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services.[3] It covers India and a region extending 1,500 km (930 mi) around it, with plans for further extension up to 3,000 km (1,900 mi).[4] An extended service area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east, 1,500–6,000 km (930–3,730 mi) beyond borders where some of the NavIC satellites are visible but the position is not always computable with assured accuracy.[5] The system currently consists of a constellation of eight [6] satellites,[7][8] with two additional satellites on ground as stand-by.[9]
The constellation is in orbit as of 2018.[10][11][12][13] NavIC will provide two levels of service, the "standard positioning service", which will be open for civilian use, and a "restricted service" (an encrypted one) for authorised users (including the military).
NavIC-based trackers are compulsory on commercial vehicles in India[14][15] and some consumer mobile phones with support for it have been available since the first half of 2020.[16][17][18][19][20]
There are plans to expand the NavIC system by increasing its constellation size from 7 to 11.[21]
