Research on scheduling rules of space target surveillance resources based on maximum number of catalogs

Abstract

Aiming at the problem that the number of spatial object catalogs is not high and the scheduling efficiency is low in traditional scheduling methods, a scheduling method using multi-rule scheduling strategy is proposed to maximize the number of object catalogs. This paper takes observation requirements and tracking arcs as inputs, forecasts the visibility of space target tracking arcs, integrates a variety of scheduling rules into the traditional scheduling process, and compares the scheduling results under two different scheduling strategies through simulation experiments with the number of multiple groups of different space targets as references. Experiments show that the same 5 monitoring devices perform the task of cataloging space objects. When the utilization rate of monitoring resources is close to 100%, the scheduling strategy based on multi-rules can achieve a maximum of 6 500 space objects stable cataloging, while the traditional scheduling strategy can only achieve a maximum of 3 200 space objects stable cataloging. Compared with the traditional scheduling strategy, the maximum number of catalogs is increased by 103%.
