Abstract: The integrated management and the rapid processing of the monitoring data of the space environment and the effects on spacecraft are an important basis for ensuring the safety of the spacecraft in orbit. In this paper, according to the functional requirements of the spacecraft environment and effect data monitoring, a specialized data management and processing system is set up, and the hierarchical structure, the framework and the data processing procedures are described. By integrating the functions of the data management and processing of the space environment and the effects on spacecraft, the comprehensive analysis of the data, the parameter calibration, and the visualized display, the system is capable of monitoring the parameters of the electrons, the protons, the total dose radiation, the atomic oxygen, the temperature, the surface potential, the contamination and other space environmental factors and the effects on spacecraft. Those parameters include the instantaneous parameters such as the particle flux, the dose rate, the temperature variations, the change of the space potential, the contamination rate, as well as some cumulative parameters such as the fluence, the total ionizing dose, the space potential, and the deposition of contaminants. All these data provide an important support for the real-time health monitoring, the rapid risk forecasting and the early warning for the spacecraft in orbit.
