India: India is all set to launch its first navigation satellite in 2013 as a part of its Gagan (GPS aided geo augmented navigation) project. Gagan is said to be a regional satellite-based augmentation system (SBAS) jointly developed by Airports Authority of India (AAI) and Indian Space Research Organisation (ISRO).
S. Ramakrishnan, director of Vikram Sarabhai Space Center (VSSC),said: “The first navigation satellite, Indian Regional Navigation Satellite System (IRNSS) will be launched with PSLV C-22 rocket in the next few months and only after all the satellites are positioned accurately in the space, the government will be able to provide navigation service through Gagan. The service is expected to be launched in 2014.”
As in news, Gagan could be used in aviation sector and help in navigation over Indian airspace. Other applications include all weather national infrastructure and can be used by defense services, security agencies, Railways, surface transport, shipping, telecom industry and personal users of position location based services. The current GPS receivers and devices are said to be replaced with Gagan receivers and devices.
