Problems solved by technology

The problem of joint allocation of satellite data receiving resources can be regarded as a multi-objective optimization problem. Usually, genetic algorithms, simulated annealing algorithms, and ant colony algorithms can be used to find optimal solutions. Although the above algorithms can obtain satisfactory optimization by traversing the entire solution space solution, but on the one hand, its time complexity is high; on the other hand, if too much consideration is given to user preferences, the algorithm model is extremely complex, and the actual engineering application is difficult

Embodiment Construction

[0029] Below, combine Figure 1 to Figure 6 The present invention is further described.

[0030] A heuristic fast satellite data receiving resource joint allocation method is characterized in that it comprises the following steps:

[0031] (1) Load satellite observation tasks and ground receiving resources, initialize the state of ground receiving resources, and set the ground receiving resource window to an unallocated state;

[0032] (2) Assuming that each ground station has only one data transmission receiving antenna and the shortest adjacent receiving resource interval is ΔT, the ground receiving resources are classified and processed for multiple satellites of the same ground station, and the first category is non-conflicting ground conflict receiving resources. The distance between this type of resource and its adjacent receiving resources is not less than ΔT; the other type is conflicting ground receiving resources, and the distance between this type of resource and i...

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 ...
