Abstract In this paper, the method of precise orbit determination and time synchronization(ODTS) is proposed to calculate the precise clock bias of two external high-precision atomic clocks, and then the performance of the system noise is analyzed. The products of IGS, Sta(published by IAC Russian space bureau analysis center) and GBMare employed for computations and comparisons respectively. The results show that the IGS and Sta clock products can be used to assess the performance of the satellite on-board clock. Furthermore, the GBM product can effectively achieve the performance evaluation of the BDS rubidium clock and the day stability of the hydrogen clock.
