The 30 Hz subcarrier FM component is demodulated in the normal manner. The reference and variable phase 30 Hz modulation components then exhibit a relative phase which is truly indicative of VOR bearing.STOVER H,US

MHz to 117.95 MHz. The ground VOR station generates a reference phase signal and a variable phase signal. The phase difference between these signals, called bearing, is function of the aircraft position with respect to the ground station. The bearing is the angle between the magnetic north and ...

One signal is constant in all directions as a reference phase. Another signal, it is variable-phase signal and it rotates through 360 degrees, like the beam from the lighthouse. Both signals are in phase when the variable signal passes 360 degrees (reference to magnetic north) and they are...

The n m-ary FSK modulating means (51-5n) shift their output frequencies in accordance with the sign of the input signals thereto based upon a common reference frequency signal from reference frequency oscillating means (8). Variable phase shifter means (471-47n) for shifting the phase of the...
