KARACHI:
Pakistan Airports Authority (PPA) has successfully completed the commissioning of state-of-the-art VHF Doppler Omnidirectional Range and Distance Measuring Equipment (DVOR/DME) at Dera Ismail Khan Airport.
DVOR/DME is a ground-based radio navigation aid used in aviation. This helps planes determine where they are and how far they are from a known point.
According to a PAA spokesperson, the project was launched in 2024 to replace the existing conventional VOR (CVOR) with an advanced navigation system, aimed at improving air navigation accuracy, operational capability and overall aviation safety.
Thanks to the professional expertise and tireless efforts of the Communication, Navigation and Surveillance (CNS) team, the project was successfully completed.
The flight inspection and calibration process of the newly installed DVOR/DME continued over the last two days and has now been successfully completed. After successful calibration, the system was officially commissioned and put into operational service.
The commissioning of DVOR/DME at Dera Ismail Khan Airport reflects PAA’s commitment to modernize aviation infrastructure and ensure safe and efficient flight operations in line with international standards, he said.
DVOR (Doppler VHF Omnidirectional Range) tells an aircraft its bearing (direction) relative to the station and uses very high frequency (VHF) radio signals. It uses the Doppler effect to improve accuracy and resistance to signal reflections.
On the other hand, DME (Distance Measurement Equipment) tells an aircraft the slant distance to the station and works by timing the exchange of radio signals between the aircraft and the ground station.
