DVORs

DVOR stands for Doppler VHF Omni Directional Range and is a form of short to medium-range radio navigation system.  

They are an International Civil Aviation Organisation (ICAO) standard navigational aid used to help aircraft determine their flight position and direction in relation to their destination. 

How Do They Work? 

DVORs assist 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. These stations hold arrays (transmitters) that spin horizontally, sending out very high frequency (VHF) signals ranging from 108.00 to 117.95 MHz. Due to their high frequency, they rely on line of sight from transmitter to receiver.  

When the receiving unit collects these radio signals (up to 200 miles from the transmitter), they can pinpoint their position and enable the aircraft to remain on course. 

CVORs and DVORs 

Here at Systems Interface, with our team of experienced engineers, we supply and install DVORs to airports across the globe. These Doppler VORs are an advancement of the previous Conventional VOR (CVOR), with enhanced signal accuracy and quality due to their ability to defer the effects of reflections from surrounding hills, mountains, and buildings. 

Why Choose Systems Interface for your DVOR Systems? 

We can supply DVOR systems and install on a full turnkey basis, or we can provide engineering expertise to support any stage of the project from site survey and safety case development to commissioning and maintenance support.

Our most recent Installation was to replace the En-Route DVOR and DME for Ports of Jersey Jersey Airport, Channel Islands, complete with full remote control and monitoring along with a new equipment shelter.

International DVOR System Projects 

Two other recent installation projects were at  Hambantota International Airport, Sri Lanka and Kopitnari International Airport, Georgia. Both systems were Indra VRB-53B DVOR's and the projects included our undertaking of all site surveys, civil works, counterpoise construction, installation  and commissioning.

We have undertaken similar projects in other parts of the world including Europe and Africa.
