摘要	This paper presents a time synchronization method based on the COMPASS code measurements in combination with two-way transfer ranging, which results the clock offset between COMPASS GEO satellite and the ground station. The clock offset of COMPASS G3 satellite on board is computed by using the data observed on October 2010. In order to verify the accuracy of this method, the results are compared with the results, which are determined only by pseudo-range observation. By comparison and analysis, the following facts can be drawn. (1) The precision of navigation satellite clock bias is better than 10 ns, when the clock bias is calculated by the new method. There is no systematic error between our results and clock bias deduced from precise satellite orbit. (2) The new method can separate satellite orbit and clock bias, it is beneficial to researching satellite clock bias.
