In order to ensure the stable operating of the satellites and detect the operating state of the satellites payloads, the detection and analysis of the navigation satellites payloads is a very important job. The detection and analysis of the satellites payloads state is to detect the operating state of the satellites, find out the variation trend of the parameters and grasp the performance variation of the important devices and single machine. Through the job, the risk and hidden trouble of the satellites system can be detected in time and the corresponding preparative scheme can be formed to ensure the safety of the satellites. On the other hand, the suitable satellites management mode basis of the navigation constellation can be established. A self-developed navigation satellite payloads state detection software and the analysis results were introduced in this paper.
