The air traffic controller (ATC) at the Sardar Vallabhbhai Patel International Airport will soon be able to identify various flying objects,even if its a bird,with the installation of a new air surveillance system,a generation-next technology.
Airport officials are being trained by German-based COMSOFT company,which has supplied similar systems to 13 other airports in the country,to get used to Automatic Dependent Surveillance-Broadcast (ADS-B),which would reduce the dependency on the existing ground-to-air radar system.
According to airport officials,ADS-B has three main components transponders fixed in the aircraft,an antenna that gets frequency from the aircraft transponder and a receiver installed at the ATC office.
It provides improved and more accurate positioning of aircraft as it can cover a distance of about 400 km around the Ahmedabad airport.
ADS-B system enhances safety by making the aircraft visible in real-time to the ATC as well as to other ADS-B-fitted planes,as position and velocity data are transmitted every second. ADS-B data can be recorded and downloaded for post-flight analysis as well. It also provides data infrastructure for inexpensive flight tracking,planning and dispatch, said an airport official.
Apart from Ahmedabad,ADS-B is installed at Guwahati,Trivandrum,Varanasi,Nagpur,Jaipur,Amritsar,Mangalore,Agartala,Port Blair,Cochin,Calicut,Coimbatore and Lucknow airports.
Earlier this year,the Airports Authority of India had announced to install two new radars Airport Surveillance Radar (ASR) and Monopulse Secondary Surveillance Radar (MSSR).
