Abstract : The patent relates to an improvement to a navigation system which includes earth satellites that carry stable oscillators which are synchronized with a stable oscillator at the navigator's station. The improvement consists of means that improve system sensitivity and reduce the effectiveness of jamming by including in the receiver at the navigator's station a tracking oscillator which is locked onto the carrier frequency received from the satellite.
