Abstract

According to the multi-satellite joint planning method and system considering task splitting provided by the invention, the task planning model is constructed. The model covers planning of detachable observation tasks and non-detachable observation tasks at the same time, a staged algorithm for planning of the non-detachable observation tasks and planning of the detachable observation tasks is designed, and various constraint conditions from satellite resource capacity level, task timeliness requirements and the like are fully considered. A large number of numerical experiments prove that through task splitting, the possibility of cooperation among multiple satellites is provided, the task completion rate is increased, multi-satellite joint observation benefits are obviously increased, and finally the observation efficiency of the satellites is greatly improved.

Description

technical field [0001] The invention belongs to the field of satellite mission planning, in particular to a multi-satellite joint planning method and system considering mission splitting. Background technique [0002] As an important space-based platform, artificial earth satellites use their own payloads (visible light, infrared, synthetic aperture radar, etc.) to complete earth observation tasks such as target observation, environmental monitoring, and resource census. Under the environment of the rapid increase in the number of satellites in operation, the continuous establishment of satellite constellations, and the gradual trend of multi-satellite cooperation, the satellite observation mode has also changed from the simple single observation and multi-satellite simple collaborative observation to the more complex multi-satellite observation mode. The development of combined collaborative observation methods. Through the close cooperation of multiple satellites, the tas...
