Abstract

The invention provides a multi-satellite task synthesis method and a system, and relates to the field of satellite synthesis. The method comprises the following steps: obtaining an observation time window and an observation angle of a to-be-observed task; averagely dividing the tasks to be observed into a plurality of task groups; obtaining an average observation angle of each task group based onthe observation angle; continuously regrouping the to-be-observed task based on the observation angle and the average observation angle until the average observation angle after regrouping is not changed to obtain a final task group, and taking the average observation angle at the moment as a synthetic observation angle; checking the final task group based on the synthetic observation angle to obtain an effective observation task set; sorting the tasks to be observed in the effective observation task set based on the observation time window; and checking the sorted effective observation task set based on a preset satellite single startup time constraint to obtain a synthetic observation strip. According to the method, the observation income of the satellite during task execution is improved.

Description

technical field [0001] The invention relates to the technical field of satellite synthesis, in particular to a multi-satellite mission synthesis method and system. Background technique [0002] With the development of aerospace technology, satellites are widely used in various fields. The user communicates the mission to the satellite, and the satellite then observes the mission target, so as to obtain the information required by the user. Generally, the multi-satellite earth observation method is used to realize it. However, due to the small number of satellites and the large demand from users, synthetic observation and batch imaging of missions are currently a major research hotspot. [0003] The existing technology generally arranges an observation for a single task, and fulfills multiple requirements put forward by users by constantly changing the camera angle of the satellite. When two ground targets are geographically close, a centered camera deflection angle is sele...
