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 an inter-satellite link scheduling method and system for a Beidou navigation satellite system. The method comprises the following steps: acquiring orbit parameters of each satellite in a Beidou navigation satellite set, a total scheduling period, a superframe duration and a time slot length contained in each superframe; constructing an inter-satellite link scheduling model of the Beidou navigation satellite system; solving the scheduling model; and outputting a scheduling scheme. According to the characteristics that an inter-satellite link presents a time-varying network along with the change of a time slot, the inter-satellite link which is a time-varying dynamic network can be described intuitively by constructing an inter-satellite link scheduling model, so thatthe scheduling solution of the inter-satellite link becomes possible; to solve the optimization problem that inter-satellite link scheduling is large-scale and long-time consumption, the invention provides an adaptive cultural gene algorithm, which overcomes the problems that the traditional local search algorithm is easy to fall into a local optimal solution, the cultural gene algorithm is high in time complexity, the constraint optimization effect is poor and the like. Large-scale daily inter-satellite link scheduling requirement of the Beidou navigation satellite system is met.

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...
