IRNSS 1C successfully launched
India is just 4 satellites away from having its own GPS.
The third in the series of seven navigational satellites, namely 'IRNSS 1C', has successfully been placed into the geosynchronous orbit.
- PSLV-C26 (Polar Satellite Launch Vehicle) rocket carried it into the space from the launchpad at the Satish Dhawan Space Centre, Sriharikota (Andhra Pradesh).
- The 1,425 kg satellite, originally scheduled for launch on October 10, was delayed due to some technical snag.
- The first two in the series IRNSS 1A (July 2013) and IRNSS 1B (April 2014) has already been launched.
Indian Regional Navigation Satellite System (IRNSS) : Our GPS
- Will have a total of 7 satellites in space expected by 2015 (3 in geostationary orbit and 4 in inclined geosynchronous orbit).
- Will have a range of 1500km (thus neighbouring countries like Nepal, Srilanka would also be able to use)
- Positional accuracy of better than 20 metres in the "primary service area" (i.e 1500km)
- Standard Positioning Service : Available for all users
- Restricted Service : encrypted service (only for authorised users like Military and other government agencies)
Some Applications (where it will be useful once all 7 satellites are in space):
- To provide accurate position information service to users (precise timing), disaster management, Navigation : (marine, aerial, terrestrial), aid to hikers, mountaineers, trekkers and other travellers vehicle tracking ; visual-voice navigation in driving; fleet management, mapping and geodetic data capture.
Other Navigational Satellite Systems:
- Global Orbiting Navigation Satellite System (GLONASS) : Russia,
- Global Positioning System (GPS) : United States,
- Galileo (GNSS) : European Union,
- BeiDou satellite navigation system (COMPASS) : China
- Quasi-Zenith Satellite System : Japan
