Jaipur: In a move to improve safety and performance of airline operations in the country, the Airport Authority of India has decided to install Automatic Dependent Surveillance Broadcast (ADS-B) across 14 airports in the country.

As the radar technology incurs heavy expenditure, the authority has decided to use ADS-B to ensure radar like surveillance. The new technology will enable aircraft flying within the range of 250-300 kilometres to be accurately tracked by air traffic controllers.

While the installation of radar requires heavy expenditure of Rs 30-70 crore, the ADS-B system will come at a cost of only Rs 70-80 lakh.

However, the other reason to opt for ADS-B technology is that nearly 25 percent of the Indian airplanes are equipped with ADS-B transponders. The surveillance system can detect only those planes which have these transponders. 

The technology will be installed at airports of Jaipur, Lucknow, Amritsar, Varanasi, Portblair, Ahmadabad, Nagpur, Kolkata, Coimbatore, Trivandrum, Bangalore, Cochin, Guwahati and Agartala.

More so, to upgrade the air traffic technology in the western part of the country, the airport authority will install radar along with ADB-S at Udaipur Airport. Presently, 18 airports have radar facility.

It is expected that the system will become functional by 2012 at Udaipur Airport.

Till now, the surveillance of air traffic control at Jaipur Airport and its vicinity was controlled by radars in Delhi.
