The performance of spaceborne atomic clock is one of the key factors that impact the accuracy of satellite navigation system positioning, navigation and timing (PNT). With the officially operation of Chinese Beidou satellite navigation system at the end of 2012, it is extremely necessary to conduct a comprehensive evaluation of the performance of the spaceborne atomic clocks. Firstly, this paper introduces two performance evaluation indices of spaceborne atomic clock and their calculation methods, namely the frequency stability and short-term prediction precision. Then, based on the measured data of Beidou satellite clock error, we make an analysis of the performance indices of the atomic clock, and the results was compared with the GPS spaceborne rubidium clocks, and thus obtained some useful conclusions, which has important significance to improve Beidou satellite navigation system.
