NavIC - Navigation with Indian Constellation (India's very own GPS system)

NavIC also means sailor or navigator in Indian languages,Some also spell it Navik

NavIC is an operational name of IRNSS(Indian Regional Navigation Satellite System), It is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services.

IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. An Extended Service Area lies between the primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.

As part of the project, the Indian Space Research Organisation (ISRO) opened a new satellite navigation center within the campus of ISRO Deep Space Network (DSN) at Byalalu, in Karnataka on 28 May 2013.[17] A network of 21 ranging stations located across the country will provide data for the orbital determination of the satellites and monitoring of the navigation signal.

The constellation consists of 7 active satellites. Three of the seven satellites in the constellation are located in geostationary orbit (GEO) and four in inclined geosynchronous orbit (IGSO).

The system is intended to provide an absolute position accuracy of better than 10 meters (33 ft) throughout Indian landmass and better than 20 meters (66 ft) in the Indian Ocean as well as a region extending approximately 1,500 km (930 mi) around India.
 
 Some applications of IRNSS are:
  • Terrestrial, Aerial and Marine Navigation
  • Disaster Management
  • Vehicle tracking and fleet management
  • Integration with mobile phones
  • Precise Timing
  • Mapping and Geodetic data capture
  • Terrestrial navigation aid for hikers and travelers
  • Visual and voice navigation for drivers
The total cost of the project was expected to be ₹14.2 billion (US$199 million), with the cost of the ground segment being ₹3 billion (US$42 million), 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 ₹9.1 billion (US$128 million).

The necessity for two replacement satellites, and PSLV-XL launches, has altered the original budget, with the Comptroller and Auditor General of India reporting costs, to March 2017, at ₹22.46 billion (US$315 million)

The NavIC signal was released for evaluation in September 2014.

In January 2020, Qualcomm launched three new chipsets, Snapdragon 720G, 662, and 460 with support for Navigation with Indian Constellation (NavIC). NavIC is planned to be available for civilian use in mobile devices after Qualcomm and Indian Space Research Organization signed an agreement.
