The first Payload Data Management System( PDMS) has been developed in China to meetthe requirements of the data acquisition,processing,recording,transmission as well as data handling for the payloads of the science experiments and space exploration on the spacecraftin future. The designs of the system adoptseveral advanced technologies corresponding to international levels of the 1990 ' s such as data transmission according to the CCSDS standard,data communication network based on15 5 3 B data bus,mass solid state recorder technology,High Rate Multiplexer and management software of PDMS. PDMS and its technical characteristics,the design and implementation of the key techniques of the system are described. The onboard test results of the miniature system composed of the key techniques in the mission of satellite are also given.
