Synthesis method and system for multi-satellite missions

Abstract

The invention provides a multi-satellite mission synthesis method and system, and relates to the field of satellite synthesis. It includes the following steps: obtain the observation time window and observation angle of the task to be observed; divide the task to be observed into several task groups on average; obtain the average observation angle of each task group based on the observation angle; treat the observation task based on the observation angle and the average observation angle Continuously regroup until the average observation angle after regrouping remains unchanged, and the final task group is obtained, and the average observation angle at this time is used as the composite observation angle; the final task group is tested based on the composite observation angle, and an effective observation task set is obtained ; Based on the observation time window, the tasks to be observed in the effective observation task set are sorted; based on the preset satellite single startup time constraint, the sorted effective observation task set is tested to obtain a synthetic observation strip. The invention improves the observation income when the satellite performs tasks.

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...
