Comparison of Indian Regional Navigation Satellite System (IRNSS) and Global Positioning System (GPS) in Vehicle Tracking Application

The Indian Regional Navigation Satellite System (IRNSS), with an operational name of NAVIC, is an autonomous regional satellite navigation system developed by Indian Space Research Organization (ISRO) in 2018 that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km around it, with plans for further extension. The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Air Force, it was launched in 1978. It is a global navigation satellite system that provides geo location and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
