In view of the landing site positioning of the lunar probe, this paper proposes a positioning reduction method based on VLBI tracking data, and applies VLBI delay-observation data from more than three baselines to complete positioning reduction with the distance between the lunar lander and the center of the earth as a constraint. Simulation results show that the positioning accuracy of landing point of the lunar lander can reach 100 m if the standard deviation of the VLBI delay-observation noise is less than 1 ns (0.3 m). This method also supports positioning reduction of other deep space probes' precise landing.
