Domestic air passengers in the country will soon be able to reach their destinations in shorter time. The Space Applications Centre (SAC) of Indian Space Research Organisation (ISRO) in Ahmedabad has developed payloads for a project called GPS-Aided Geo Augmented Navigation (Gagan) which will enable better Navigation of flight routes to cut down the distance and time between two places in the country.
Gagan is a joint project of ISRO and Airports Authority of India (AAI) to manage flights in a better and more reliable way. Until now, the management of flights in the country has been based on GPS data obtained from US.
With the help of Gagan, pilots and the Air Traffic Control (ATC) at airports will be able to locate the exact positioning of an aeroplane, regardless of wherever it is, with the help of satellites. "At present, aeroplanes can communicate their locations and positions directly with the airports only when they are within a certain range. Hence aeroplanes do not take a linear path but fly such that they are always within the range of one airport after another," said AS Kiran Kumar, director of SAC.
Talking about other ways in which AAI will be able to benefit from Gagan, Kumar said, "It will also help in monitoring the speed of the wind blowing from the opposite direction along the path of the flight. As wind speeds can significantly reduce the speed of the aeroplane and increase the travel time, the route could be modified accordingly to divert such winds."
The first Gagan navigation payload slated on GSAT-8, was launched on May 21, 2011. The second Gagan payload is scheduled to be launched on GSAT-10 around August 2012. "Gagan can become functional after the second payload is launched," said Kumar.
The main payload for Radar Imaging Satellite (RISAT-1) which was launched on Thursday was built in SAC. RISAT-1 uses microwaves which can penetrate clouds and take images if the earth surface bit during day and night and provide critical data inputs for a range of applications. Apart from building the payload, a film to explain the details and function of RISAT-1 was also made by senior producer at development and educational communication unit at SAC campus.
