SATELLITE BASED AIR NAVIGATION OF INDIAN AIRSPACE


Satellite Based Air Traffic Management Services for the Indian Airspace in the offing. The Indian Space Research Organisation in coordination with the Airports Authority of India is working on a Technology Demonstration Project for this Satellite Based Augmentation System. The Project is the first step towards introduction of a consolidated satellite based on communications, Navigation, Surveillance Air Traffic Management system for the Indian Airspace.

The Technology Demonstration System will have the necessary infrastructure in space and on ground to prove the efficacy of the project. Initially for this, a network of ground reference stations, a master control station, ground up link station and satellite navigation payload in space, etc. are being planned. A time-frame of four years has been set for its demonstration.

The Demonstration project is part of a national plan for satellite navigation over Indian Airspace. Then it will enter the initial Experimental phase and finally, the operational phase. The Indian space based Augmentation System is also expected to bridge the gap in the European Geo-stationary Navigation overlay system and the Japanese Space Augmentation System, to provide seamless navigation of aircraft from West to East and vice-versa. When operational it will play an important role in the introduction of air-navigation services in the whole Asia-Pacific region.
