Navigation and Observation Systems
DVOR 2000. Doppler VHF Omnidirectional Radio Range

PURPOSE

The Radio Beacon is designed to generate and transmit radio signals which provide measuring of the azimuthal angle of an aircraft equipped with VOR avionics. The Radio Beacon is used in airports and on routes of civil aircrafts.

PERFORMANCE CAPABILITIES

The DVOR 2000 Radio Beacon has the signal format of VOR avionics and conforms to the requirements applied to this equipment as set forth in «Appendix 10 to Convention on International Civil Aviation (ICAO)». The Radio Beacon can be used in package with distance measuring DME/N Radio Beacon as well as independently.
