Description

technical field [0001] The invention relates to the field of mission management and control of aerospace and ground systems, in particular to a rolling remote sensing satellite dynamic mission planning method based on timing of measurement and control, which is suitable for satellite mission planning under the condition of high requirements for fast response and timeliness of missions. Background technique [0002] The existing remote sensing satellite task management and control system, in order to cooperate with daily duty, mostly adopts a batch-processing task planning method with a daily cycle. Each satellite generally performs task planning once a day, and once plans and arranges observation tasks within 24 hours. Although it is more effective in resolving resource conflicts, when there are a large number of satellites in orbit, the task load will increase significantly, and the task dynamic changes frequently, and the requirements for quick response to the task are high...

Problems solved by technology

Although it is more effective in resolving resource conflicts, when there are a large number of satellites in orbit, the task load will increase significantly, and the task dynamic changes frequently, and the requirements for quick response to the task are high. Process, in the face of emergencies and emergency adjustment tasks, the insertion of emergency tasks may affect the 24-hour on-board task execution, the task adjustment is not flexible and fast enough, and there are satellite security risks

Moreover, it takes one to two days for users to submit observation requirements before they can be scheduled for execution, so this mode cannot cope with emergency normalized task management and control

The construction of the future mission management and control system puts forward higher requirements for the rapid response capability of the mission. The existing fixed-duty cycle mission control mode for routine census missions can no longer meet the timeliness requirements for rapid mission adjustment under the normalization of emergencies and shorten the satellite mission planning time. The interval is imperative, and it is necessary to adopt a rolling dynamic task management and control mode for quick response tasks to shorten the time period from request acceptance to data acquisition, thereby improving the rapid response capability of the system
