Abstract

The present invention discloses a heuristic rapid satellite data receiving resource joint distribution method. Aiming at the problem of the multi-ground receiving resource for the multi-observation satellite joint optimization distribution, in consideration of continuously coming observation task and the observation requirement on the a satellite with high timeliness requirement, a heuristic rapid satellite data receiving resource joint distribution method is designed. The method comprises: distributing non-conflicting resource, distributing conflict receiving resource for the real transmission and the task at an assigned ground station in order according to the priority from high to low, and finally distributing the conflict receiving resource based on the minimum task filling rate satellite priority principle. The method is simple in determination logic, high in resource use ratio and low in time complexity, especially has the capacity of replying emergency and complex business variation.

Description

technical field

[0001] The invention relates to a heuristic fast joint allocation method of satellite data receiving resources, which is particularly suitable for the field of fast joint optimal allocation of receiving resources of multiple ground stations to multiple observation satellites. Background technique

[0002] The space-to-earth observation system includes multiple observation satellites and multiple ground data receiving stations. Factors such as the orbit of the satellite and the geographical location of the ground station lead to the phenomenon that multiple satellites are visible to a single station at the same time, and a single satellite is visible to multiple stations at the same time. , the non-uniform distribution of observation tasks and ground receiving resources on the time axis increases the difficulty of matching between observation tasks and ground receiving sources. How to allocate multiple ground station receiving resources to multiple observation ...
