Abstract :
A dual one-way ranging system (DOWR) can provide very high precision ranging between two carrier phase transceiver-receiver systems. In microwave ranging system, the accuracy of inter-satellite ranging is mainly limited by the stability of the oscillator and the accuracy of phase measurement. In K/Ka band, the Micron level ranging requests that the phase measure achieves 0.0006rad measurement precision. This paper presents a novel design of the carrier tracking loop, and analyses the realizability of Micron level ranging in the atomic clock phase noise and channel noise condition.
