Embodiment 1

[0027] Such as figure 2 As shown, the present invention provides a multi-level satellite coordinated scheduling system, which at least includes a scheduling optimization module 1 , a scheduling execution module 2 , a satellite status monitoring module 3 and a demand processing module 4 . The scheduling optimization module 1 can analyze different variables for scheduling satellites to simulate the actual operation behavior of satellites and optimize and adjust the schedule for scheduling satellites 5 and ground stations 6 according to satellite feedback data. Scheduling the satellite 5 and the ground station 6 through the optimized and adjusted schedule can obtain better satellite resource utilization efficiency. The scheduling optimization module can dynamically modify the schedule in response to new tasks, unexpected events, or satellite performance changes. The entire optimization and adjustment process can be carried out without human intervention, and it can ignore the un...

Embodiment 2

[0040] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0041]Preferably, the satellite coordinated dispatching system further includes a control command generation module 7 . The control command generation module is configured to be able to generate a first control command set according to the action tasks of the satellites and / or ground stations, and the first control command set includes a list of action tasks of several satellites and / or ground stations. The control command can be displayed in a binary manner to indicate its status, for example, when its value is "1", it means "execute action task", and when its value is "0", it means "skip action task". Control commands can be used to describe the problem to be solved and the user controls the execution or non-execution of other tasks associated with the action task. For example, when a satellite is performing an imaging task, the control command can instruct the...

Abstract

The invention discloses a multi-level satellite cooperative scheduling method and system. A scheduling optimization module is configured to perform optimization adjustment on a schedule according to the following modes: generating a first control command set based on an action task of a satellite and / or an action task of a ground station, and generating a conflict set associated with the first control command set at least based on the state of the first control command; selecting a first control command requiring a change in state based on the first control command set and determining a utility penalty based at least on a conflict associated with the first control command in a case where a state change of the first control command is performed; calculating a utility value of the first control command, correcting the utility value based on the utility punishment, and accepting the state change of the first control command when the utility value is increased. According to the method, theinfluence caused by the change of the state of the control command can be quickly evaluated again under the condition that other control commands are not considered, and the optimization adjustment of the schedule can be completed at a faster speed.

Description

technical field [0001] The invention belongs to the technical field of satellite control, and in particular relates to a multi-level satellite coordinated scheduling method and system. Background technique [0002] Different types of satellites can perform tasks such as communication or observation either individually or in concert. For example, Earth observation satellites can image certain areas of the Earth at specific times through the sensors they carry. Using a single satellite to work independently cannot effectively image the entire earth in a short period of time. Or when it is necessary to perform a temporary observation task in a certain area, based on the orbit, altitude and field of view of the satellite, it is often impossible to quickly respond to the execution of the observation task. In order to reduce the time required for the overall imaging of the earth or to quickly respond to the execution of temporary observation tasks, a large number of remote sensi...
