A watchful eye on Jaipur sky now

Jaipur: Forget about ground-based radar air surveillance on Indian airports. Now, civilian aircraft will self-communicate with airports, their identity and speed, through an air-borne surveillance system, likely to come up by 2012 at 14 Indian airports, including Jaipur International Airport at Sanganer.
The Automatic Dependent Surveillance-Broadcast (ADS-B)-based air surveillance system is likely to become operational by 2012 at 14 airports, including Jaipur, Agartala, Imphal, Bhopal, Patna, Lucknow, Amritsar, Varanasi, Port Blair, Nagpur, Ahmedabad and Calicut, a senior Airports Authority of India (AAI) official from New Delhi informed on Tuesday.
Tendering exercise has already begun, said an AAI official in Jaipur attending an Asia-Pacific civil aviation meet.
Unlike, the present technology of radar-based ground-to-air air surveillance system on airports, the relatively cheaper air-borne surveillance ADS-B system, entails three components- an ADS-B transponder fitted in the aircraft, an antenna to get frequency from the aircraft transponder and a receiver at the ground Air Traffic Control (ATC), which makes airports aware about identity of the plane, its speed, flight height level and other critical information.
