Abstract

The invention provides a satellite screening method and system based on task invitation, and relates to the field of satellite scheduling. The method comprises the following steps: acquiring historical task data, wherein the historical task data comprise historical tasks and satellites corresponding to the historical tasks; acquiring a historical task demand vector based on the historical task; obtaining a to-be-observed task demand vector based on the to-be-observed task; obtaining the similarity between the historical task and the to-be-observed task based on the two demand vectors; obtaining a target historical task based on the similarity, and extracting a target satellite corresponding to the target historical task; inviting the target satellite based on the to-be-observed task; if the target satellite meets the energy constraint, the storage capacity constraint and the task time window constraint at the same time, enabling the target satellite to accept the invitation to obtain an invited satellite; if the number of the invited satellites is one, enabling the invited satellite to execute the task to be observed; and if the number of the inviting satellites is more than one, executing the task to be observed by the inviting satellite with the maximum income when the task to be observed is executed. The method and system are high in satellite screening efficiency.

Description

technical field [0001] The invention relates to the technical field of satellite scheduling, in particular to a satellite screening method and system based on task invitation. Background technique [0002] With the development of aerospace technology, earth observation satellites have attracted more and more attention. Earth observation satellites obtain relevant information by detecting the Earth's surface and lower atmosphere. Earth observation satellites have unique advantages such as wide coverage, long duration, and no airspace and national boundaries. Therefore, earth observation satellites are widely used in military reconnaissance, meteorological observation, and environmental protection. [0003] For a satellite observation task, how to select a suitable satellite to perform the observation task among the many available satellite resources is a big problem. In the prior art, the matching method of observation tasks and execution satellites is generally as follows:...
