An Autonomous Aggregation Method for Remote Sensing Satellite Imaging Tasks

Abstract

The invention discloses a remote sensing satellite imaging task autonomous aggregation method which comprises steps of firstly, identifying the task density degree in a local planning window range, judging whether the candidate to-be-observed task set needs autonomous aggregation of remote sensing satellite imaging tasks or not; when the autonomous aggregation is needed, dividing the candidate to-be-observed task set to obtain a plurality of dense task subsets; then, calculating external polygons of the dense task subsets respectively; determining a task aggregation mode of the dense task subsets according to the external polygons of the dense task subsets; dividing each dense task subset into a plurality of strip observation subtask sets and a region observation subtask set; and finally,generating a plurality of strip observation aggregation tasks according to the plurality of strip observation sub-task sets, performing push-broom strip division, generating a region observation aggregation task according to the plurality of region observation sub-task sets, and performing push-broom strip division to complete autonomous aggregation of the remote sensing satellite imaging task.

Description

Technical field [0001] The invention relates to an autonomous aggregation method for remote sensing satellite imaging tasks, belonging to the technical field of spacecraft autonomous task planning. Background technique [0002] Remote sensing satellites with autonomous mission planning capabilities need to face the problem of multi-source complex mission input. The mission sources include imaging missions proposed by multi-source terminal users, high-priority imaging missions for ground emergency injection, and the passage of pre-order satellites in multi-satellite coordination scenarios. The coordinated guidance task sent from the inter-satellite link, and the imaging task independently discovered and generated by the on-board sensing and decision-making module. Because the above-mentioned multi-source imaging tasks have not been coordinated and processed by the ground management and control system, there is a feature that the ground targets to be observed in a local area are de...
