A high-precision inter-satellite velocity measurement method based on two-one-way laser Doppler is presented in this paper. This method's working principle and signal-to-noise ratio's effect under different measurement times of signal on velocity precision are analyzed theoretically. This method is also tested by laboratory experiments and 1 mm/s velocity precision is achieved in 1 ms integrating time. The proposed method potentially contributes to inter-satellite velocity measurement, especially for the relative velocity measurement between two satellites in high dynamic motion and a long distance apart.
