Chennai: Pilots who fly in and out of the city airport are in for a Christmas treat. The Airports Authority of India (AAI) is working towards completing the Ground Based Augmentation System (GBAS), which will provide pilots error-free positioning data courtesy satellite signals, by early December.
“This is the first airport that has this system in Asia and we are working towards completing it in the next 6-7 months, including testing,” said an AAI spokesperson. Currently being installed at the airport, the system will easily handle both runways and make a system like the existing ILS (Instrument Landing System) nearly redundant.
Once it is ready, it will not only eliminate position errors caused by a plane’s Global Positioning System (GPS), it will also display the corrected flight path on the pilot’s screen automatically. “The system is on the ground and it has GPS satellites, a processor and a VHS transmitter,” explained an avionics expert with AAI. “It takes the data from four GPS satellites and compares it with the real-time positioning and corrects errors that a single GPS satellite might commit,” he added.
Once the plane’s error-free positioning is calculated, signals are sent via VHF to the plane, where the signal is received and computed to the auto-pilot system.
