India will soon have a positioning system of its own. Much like our own GPS, the Indian Regional Navigation Satellite System (IRNSS) is scheduled to provide location information to civilians and government users alike, with a position accuracy of 20 meters or better. Seven satellites will make up IRNSS, including three in geostationary orbit and four in inclined geosynchronous orbit, which will rotate with the Earth. GPS currently covers the Indian subcontinent, as it does the rest of the world -- like GLONASS in Russia and BeiDou in China, IRNSS will provide additional utility to users within 1,500 kilometers of the Indian mainland. It's expected to come online by 2016.
