IRNSS [ISRO]
The Indian Government has approved in May 2006, a project to implement an Indian Regional Navigation Satellite System (IRNSS) in the next six to seven years. It will consist of a constellation of seven satellites and a large ground segment. Three of the seven satellites in IRNSS constellation will be placed in Geostationary Earth Orbit and four in Geosynchronous Orbits inclined at 29° to the equatorial plane. All the seven satellites will have continuous radio visibility with Indian control stations.
