ABSTRACT:
A radio position-fixing system using hyperbolic phase measurement, includ two transmitting stations which radiate a specific, programmed, sequential and recurrent waveform and a movable receiver capable of synchronously receiving and detecting the transmitted waveforms and, by combining the signals in a predetermined manner, measuring certain phase differences in the signals which are representative of the hyperbolic position-line information for the receiver relative to the two transmitters.
