Embodiment Construction

[0098] The following will combine figure 1 The method of the present invention is described in further detail.

[0099] This embodiment provides a satellite on-orbit autonomous task planning method, which is used for the observation of the ground area target of the small remote sensing satellite constellation, which mainly includes two steps: (1) the satellite acquires the task and determines the single area task to be executed currently; (2) The satellite obtains the observation trajectory of the current single regional task to be performed.

[0100] Instructions are given below:

[0101] 1. Step (1): Mainly realize the preprocessing and distribution of multi-tasks, sort the task groups uploaded to the constellation, and obtain the tasks performed by the satellites at each time. The process is as follows:

[0102] 1.1. The satellite receives and uploads task groups;

[0103] 1.2. Prioritization of tasks

[0104] Define tasks as meta-tasks, and distinguish the differences ...

Abstract

The invention discloses a satellite on-orbit autonomous task planning method and a satellite on-orbit autonomous task planning system. The planning method comprises the steps that (1) a satellite obtains a task and determines a single area task to be executed currently; (2) the satellite acquires an observation track of a single region task to be executed at present; 1.1, receiving an uploaded task group by a satellite; 1.2, performing task priority ranking on the tasks in the task group, and performing task yield ranking on the tasks in the same priority to obtain a task queue; and 1.3, selecting a single regional task with high task priority and high task yield as a single regional task to be executed at present. According to the method, the tasks are reasonably sorted, so that dynamic conditions and tasks with different priorities can be better responded. According to the method, the performance of the agile satellite can be fully utilized, and the problem that the solving conditionof the micro remote sensing satellite group in the earth region task planning process is complex is solved.

Description

technical field [0001] The invention belongs to the technical field of satellite-to-earth region target observation, and in particular relates to a satellite on-orbit autonomous task planning method and system. Background technique [0002] The small remote sensing satellite constellation has the characteristics of strong maneuverability and a large number of satellites, and can achieve rapid task response to ground area targets. It is one of the main development directions of imaging satellites at present. [0003] In the traditional mission planning, the ground control center needs to process the task area, divide it into task strips suitable for satellite execution, and then use a certain algorithm to assign the task strips to satellites for execution. Because the traditional strip decomposition method has overlapping strips in multi-satellite cooperative missions, it is difficult to obtain optimal results for ground area targets, which makes the solution difficult and ca...
