Abstract
The purpose of satellite tracking telemetry and control (TT&C) resource scheduling is to scientifically allocate limited ground TT&C resources, and to maximize the scheduled tasks of satellite TT&C through a certain scheduling method. Due to the sharp increase in satellite numbers, Traditional scheduling methods face challenges with more TT&C tasks, more resource competition and more emergencies. As the agent is independent, flexible, intelligent and distributed, we introduced agent technology to solve the problem. Combining characteristics of multi-satellite TT&C resource schedule with description method of attribute, interaction, rule and state on agent technology, we established four agent models: manager agent, station agent, equipment agent and task agent. Then, by analysing the requirements of satellite TT&C engineering, we proposed a comprehensive weighted priority determination method to determine TT&C resource allocation. Last, we simulated real application scenarios to validate this method. And it proves to be effective.
