Embodiment Construction

[0022] In the drawings, the same or similar reference numerals are used to denote the same or similar elements or elements having the same or similar functions. Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] In the context of the normalization of dynamic observation requirements, satellite resource status information and mission information at any moment are temporary, so it is impossible and unnecessary to consider all or large-scale mission information that is not fully clear at present when planning. This embodiment mainly introduces that the coordination control sub-module effectively controls other sub-modules, and determines the tasks to be planned and the task planning time. The following first introduces the basic idea of ​​the coordinated control strategy and the design method of multiple windows, then establishes the finite state machine model of the coordinated control strategy, and intr...

Abstract

The invention discloses a coordinated control strategy of an agile earth satellite. In the coordinated control strategy of the agile earth satellite, each complete scheduling process and a satellite implementation and execution scheme are conducted simultaneously in terms of time, a part of satellite motions in the motion scheduling scheme are selected after motion scheduling ends to establish anexecution window, and a satellite motion sequence in the execution window serves as the final scheduling result of scheduling, namely the execution scheme. Each complete scheduling process of the coordinated control strategy includes the following steps of establishing a task scheduling rolling window, scheduling a task, establishing a motion scheduling window, scheduling motions and establishingthe execution window.

Description

technical field [0001] The invention relates to the technical field of observation satellites, in particular to a coordinated control strategy for agile ground-to-earth satellites. Background technique [0002] The planning schemes implemented by most of the earth observation satellites are generated by the ground mission planning system, and then uploaded to the satellite through the satellite-ground link. This "big loop of heaven and earth" management and control mode takes a long time from demand collection to data collection to product generation, and cannot meet the timeliness requirements of the future earth observation system at all. Compared with the "big loop of heaven and earth", the satellite autonomous planning technology has great advantages in improving the satellite's rapid response ability to dynamic observation needs, improving the multi-satellite coordination ability, and reducing the dependence on the ground measurement and control system, so it is very su...
