Abstract
A hyperbolic navigation receiver locates ships, and the like, by phase-locking the output signal of the voltage-controlled oscillator or voltage-controlled phase shifter of respectively provided tracking loop filters corresponding to the incoming signals from a master and slave station. The voltage-controlled oscillator or voltage-controlled phase shifter is caused to produce an output signal which is a multiple frequency of the incoming signal. Phase discrimination of the output signals is undertaken without the use of a multiplier.
