Description
Summary:Ground Test Platform for Space Teleoperation (GTPST) is a complicated distributed system consisted of multiple subsystems, and controlling it properly under large transmission delay is a huge challenge. Multi-agent System (MAS) is an effective method of solving distributed problems logically and physically, which has such merits as high adaptability, high reliability and easy to expand and maintain. The control model of GTPST is established based on MAS in this paper. Due to the limitation of the available network bandwidth and the large time delay of satellite-ground links, we develop some applications based on mobile agent which can perform its execution locally on remote site, only return the final result or desired data back to local site. As no operation and communication between remote and local sites are needed during the execution of the mobile agent, valuable bandwidth can be reserved and saved. Meanwhile, communication protocols of MAS are improved and designed to increase the communication efficiency of the system. The availability of the system is verified by the test the Simulated Service Satellite (SSS) replaces cell unit for the simulated client satellite (SCS) finally.
