India: India is considering to provide GAGAN ((GPS-aided geo augmented navigation) system to countries of South-East Asia in a bid to generate financial returns and demonstrate its next-gen navigation and surveillance technologies.
G.M. Siddeshwara, Minister of State for Civil Aviation said that, "“to promote the usage of Gagan in the non-aviation sector, AAI and the Indian Space Research Organisation have organised two user meets”.
“The possible users might come from the ASEAN (Association of South East Asian Nations). There are also plans to provide global navigation services by clubbing Gagan’s capabilities with that of the US Global Positioning System (GPS), Russian GLONASS, European Galileo, Chinese Compass, Japanese Quasi Zenith Satellite System, said a senior official of the Airports Authority of India.
Gagan provides free enhanced satellite navigation signals over India that are 10 times more precise than GPS. Satellite-based location systems like Gagan can be used to render GPS-based location of the aircraft to pilot as well as real-time satellite-based location to ground handlers.
As a a satellite-based augmentation system, it helps aircrafts navigate by GPS (hitherto seen in passenger cars) rather than ground-based radar tracking systems. This results in enhanced accuracy, continuity and integrity of navigation services.
