英文摘要	We illustrate the principle of Digital satellite TV differential timing (DSTVDT) and propose an optimal weighting method that reduces the timing error introduced by satellite ephemeris error. A mathematical formula for the timing error introduced by satellite ephemeris error is derived and analyzed. On the basis of the derived formula, the proposed optimal weighting method based on multi-base stations is presented. The results of data simulation and experiments show that when the proposed method is applied, for a satellite ephemeris error of 10km, the ephemeris-introduced timing error is less than 10ns, which is important for improving accuracy and stability of the timing system.
