KARACHI:
Pakistan Airports Authority (PPA) has successfully completed the commissioning of an advanced Doppler VHF 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. It helps aircraft find out where they are and how far they are from a known point.
According to a PAA spokesperson, the project was initiated in 2024 to replace the existing conventional VOR (CVOR) with an advanced navigation system aimed at improving accurate air navigation, operational capability and overall aviation safety.
Due to the professional expertise and tireless efforts of the Communications, 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 past two days and has now been successfully completed. After successful calibration, the system is formally commissioned and commissioned.
The commissioning of DVOR/DME at Dera Ismail Khan Airport reflects PAA’s commitment to modernize aviation infrastructure and ensure safe and efficient air operations in accordance with international standards, he said.
DVOR—Doppler VHF Omnidirectional Range—tells an aircraft its bearing (direction) from 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 Measuring Equipment — tells an aircraft the slant distance to the station and works by timing radio signal exchanges between the aircraft and the ground station.
