The satellite-ground two-way clock correction data is usually adopted in the satellite clock performance evaluation.Two types of new analysis data source including satellite phase difference data and multi-satellites orbit determination clock difference data were introduced in this paper for comprehensive satellite clock performance evaluation.In order to assure the accuracy of the evalua-tion results,the satellite clock performance evaluation should not only be evaluated by different methods with different data,but also be verified by the satellite clock performance evaluated by different data.The measuring and calculating principle and precision was provided in this paper.The consistency of clock correction and performance evaluation was compared.The results show that satel-lite phase difference data and satellite-ground two-way clock correction data can preferably evaluate the performance of satellite clock and the evaluation consistency is very high; the orbit determination error in multi-satellites orbit determination clock difference cant be totally separated,which will influence the satellite clock frequency stability.
