A study is conducted to propose a novel dual-transponder ranging (DTR) approach to intersatellite distance measurement with high accuracy. The novel approach can achieve the same level of accuracy without the requirement of a high-precision time-tagging system as compared with the earlier dual one-way ranging (DOWR) approach. The proposed DTR system consists of a leading and trailing part, and the microwave signals are generated in two ways by different multipliers in the leading part. The leading part plays a role of an interferometer, while the trailing one acts as a radio-frequency mirror to produce phase-locked signals.
