| Abstract: |
| In this paper, the composition of GPS system is briefly introduced.The configuration of the frequency standard researched and the working principle of each components are described in detail. The two testing methods of performance and the testing instruments used for the frequency standard are given. The testing result and some factors of uncertainty of measurement are analyzed in reason. |
