摘要	Based on the deep analysis of the wide area differential principle on the separation of satellite ephemeris errors and clock errors, the similarities and differences between the absolute separation of satellite ephemeris errors under time synchronization among the differential stations and relative separation of them under no time synchronization among them are analyzed. A one-station correction method of satellite clock errors including the 1st and the 2nd step correction is given under no time synchronization among these secondary stations, and the backward inference algorithm of the second correction of satellite clock errors is proposed. Through simulation analysis, satellite time service accuracy with code phase measurement can reach 5-7 Ins, and that with carrier phase smoothing pseudo-range can reach 1-3 ns.
