How does a VOR signal work?

This being said, how does VOR antenna function?

The VOR antenna on an aircraft is usually located at the tail and picks up the signal and transmits it to the receiver in cockpit. The VOR receiver in the aircraft compares the VOR's reference and variable phases and determines the aircraft’s bearing from the station.

Is VOR being phased out? The plan calls for 74 VORs to be decommissioned during Phase 1, which will continue through 2020. 234 additional VORs will also be decommissioned under Phase 2, which will take place between 2021-2025.

Also, what is the range for a VOR signal?

VOR stations located in areas of magnetic unreliability have True North orientation. The "radial" is the line of position from the VOR. The position of an aircraft is determined by crossing two radials from different stations. VOR signals can travel approximately 200 miles.

What is the difference between VOR and Vortac?

A VORTAC combines VOR and TACAN at one location. The VOR signals are used by civil users. They have the same performance and capabilities as the VOR signals. They also use the DME from TACAN. A VORTAC is effectively a VOR/DME.
