DABOLIM: Goa International Airport has become the first to install the Doppler Very High-Frequency Omni Range (DVOR ) system for safe navigation of flights.
“Joint efforts by the team has led to successful replacement, installation and flight calibration work for new DVOR(MARU-220), HP-DME(MARU-320) & LP-DME(MARU-310) (Mopiens, South Korea) for enhanced safe operations,” said Airport Director Gagan Malik
He said that the entire project costs Rs five crores and that DVOR is a standard International Civil Aviation Organisation (ICAO) ground-based radio navigational aid that provides bearing information to aircraft to define air traffic control routes en-route, terminal and instrument approach/departure procedures.
“DVOR, when collocated with DME (Distance Measuring Instrument), provides both the angle and slant distance of aircraft concerning ground station,” he added.
The airport director said that DVOR, when collocated with DME, provides both the angle and slant distance of aircraft with respect to the ground station.
“We have upgraded the DVOR, which was ten years old, and this latest technology is being used for the first time in India,” said Malik
The DVOR assists aircraft in their approach by sending omnidirectional signals from ground radio beacons located at airports and runways. These signals are sent from transmitters located in a network of VOR stations.
