4 airports to get new air surveillance technology

Agartala: The Airports Authority of India (AAI) is to introduce a new radar-based air surveillance system at 14 airports across the country for better control of aircraft in flight, an official said.
"The new Automatic Dependent Surveillance-Broadcast (ADS-B) system would facilitate civilian aircraft in self-communicating with airports about their identity, speed and altitude," AAI director Sudhamay Maiti told IANS.
"The new system is likely to be commissioned in six to seven of a total of 14 airports across India by the middle of this year and in the remaining airports by this year-end," he added.
According to the official, unlike the existing radar-based ground-to-air surveillance system on airports, the comparatively cheaper ADS-B system has three components -- an ADS-B transponder in the aircraft, an antenna to get frequency from the aircraft transponder and a receiver at the Air Traffic Control (ATC).
"The new technology enables ATCs at airports to get complete situational awareness of ADS-B compatible aircraft, which could even be 300 miles away," Maiti said.
