Embodiment Construction

[0060] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0061] Figure 1 to Figure 6 It shows a specific embodiment of a Beidou navigation satellite system inter-satellite link scheduling method of the present invention. The specific experimental scene of this embodiment is: through a 7-day BDS inter-satellite link scheduling experiment to illustrate the present invention effectiveness. BDS includes 24 medium earth orbit satellites (Medium Earth Orbit, MEO), 3 geostationary orbit satellites (Geosynchronous Orbit, GEO) and 3 inclined geosynchronous orbit satellites...

Abstract

The invention provides a Beidou navigation satellite system inter-satellite link scheduling method and system, including obtaining the orbit parameters of each satellite in the Beidou navigation satellite set, the total scheduling period, the superframe duration and the time slot length contained in each superframe; A Beidou navigation satellite system inter-satellite link scheduling model; solving the scheduling model; outputting a scheduling plan. According to the time-varying network characteristics of the inter-satellite link as the time slot changes, by constructing the inter-satellite link scheduling model, the time-varying dynamic network of the inter-satellite link can be described intuitively, so that the inter-satellite link It is possible to solve the scheduling problem; for the inter-satellite link scheduling is a large-scale and long-term optimization problem, an adaptive cultural gene algorithm is proposed, which overcomes the traditional local search algorithm that is easy to fall into the local optimal solution, and the cultural gene algorithm is time-complex It meets the problems of high degree of accuracy and poor constraint optimization effect, which meets the large-scale daily inter-satellite link scheduling requirements of the Beidou navigation satellite system.

Description

technical field [0001] The invention relates to the field of mission planning and dispatching, in particular to a Beidou navigation satellite system inter-satellite link dispatching method and system. Background technique [0002] On June 23, 2020, the 55th Beidou navigation satellite was successfully launched, marking the official establishment of the third-generation Beidou Navigation Satellite System (BDS for short) in China, and the domestic satellite navigation system has entered a new era. In recent years, BDS has provided global navigation and positioning services for users around the world, playing an important role in logistics, transportation, aerospace and other fields. In BDS, the inter-satellite link can reduce the dependence of the navigation system on the ground control system, improve inter-satellite ranging, communication capabilities and system accuracy, and is an important part of BDS. [0003] The inter-satellite link of BDS refers to a wireless communic...
