The number of space objects is increasing rapidly with the expansion of human's space exploration. So space debris has become a serious pollutant which poses a great threat to spacecraft. It is necessary for us to establish the space objects database management system to keep these objects under surveillance. The system structure, software and hardware environment, database structure and results of the space objects database management system are discussed in this paper. This database management system can provide some bases for efficiency use of space objects data, as well as excellent data service for space objects surveillance system and collisions avoidance analysis.
