Chennai: Pilots and air traffic controllers have called ISRO’s Indian Regional Navigational Satellite System (IRNSS) a boon to the Indian aeronautical sector as they would get micro-level Indian data from the indigenous satellite system.
“It is a great achievement by ISRO. We will now have our own satellites to access global positions. Till today, we have been using GPS owned by the US and Russia’s Glonass for our air navigation,” said V. Somasundaram, member, Air Navigation Services, Airports Authority of India (AAI).
Pointing out that these global satellites are free of cost and used by all countries across the globe as per their requirements, Somasundaram noted that it would be reliable and advantageous to have our own satellites. “ISRO is poised to launch a couple of satellites and in the next stage. It would be on a par with GPS,” he added.
He noted that the pilots have on board systems that use GPS (global positioning system) to identify coordinates and act accordingly. Similarly, the air traffic controllers would also use GPS to find the actual position of the aircraft.
“The satellite would help us get a clear position of the aircraft with just a plus or minus three metres variation.
Further, we also need not depend on external agencies,” said Air Traffic Controllers Guild (India), president D.S. Raghavan.
However, according to S.V. Satish, GM, Gagan project, it might take sometime for the aviation industry in India to start using this satellite.
“We have to integrate this satellite with Gagan (GPS and geo-augmented navigation) system and then take permission from the International Civil Aviation Organisation to use it,” he pointed out.
Saying that many satellites are now put into space, he said we have to wait and watch, how it develops in the future. Informed sources said the satellite would have more defence-oriented use and help space research.
