IRNSS meaning in Governmental ?

The 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), is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km (930 mi) around it, with plans for further extension. 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. The system currently consists of a constellation of seven satellites, with two additional satellites on ground as stand-by.

The constellation is in orbit as of 2018, and the system was expected to be operational from early 2018 after a system check. 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 and it is planned to become available in consumer mobile phones in the first half of 2020.

There are plans to expand the NavIC system by increasing its constellation size from 7 to 11.
