DVOR-JJB (CNS-Navigational aids)

DVOR Stands for Doppler Very High Frequency Omni Range. 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 for 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 with respect to ground station.

No one can tell difference between DVOR and normal VOR. Its only written in approach plate and nowdays all VORs are used in combination of DME. Its good that we are getting CAT II ILS.
