Method for setting multilayer satellite network system route

Abstract

The present invention relates to a method for setting multilayer satellite network system route, including steps of: 1. setting parameters for the network initialization; 2. fixing a time, solving satellite orbit parameters in the interval of time, calculating the location coordinates of the satellite and the length of the link between stars, and establishing a network topological structure; 3. calculating the load of link between stars of the multi-layer satellite network; 4. calculating the process and exchange time delay on stars according to the queuing theory; 5. searching source satellite and object satellite of each satellite layer; 6. selecting the satellite layer for transporting services according to the communication service instruction requirement and network states, and searching an optimum route according to routing algorithm. Relative to traditional stationary orbit satellite, the present invention has small transmission delay, and high validity. The system has advantages of more flexible routing, effective guaranty of service quality, multiple replaceable chain circuits, stronger survivability, a capacity of processing and exchanging on star, optical or microwave links between stars, and capability of providing wideband synthetic service for users in global scope.

Description

technical field [0001] The invention belongs to the field of deep space communication, and in particular relates to a multilayer satellite network system routing setting method. Background technique [0002] Early satellite communications often used a single geostationary orbit satellite with an orbital altitude of about 35,786 kilometers and an orbital inclination of 0 degrees. It was located at a certain longitude position above the equator and was stationary relative to the ground. Geostationary orbit satellites have a high orbit and a large coverage area, but due to the large communication distance between the satellite and the ground, the link is easily damaged, and it does not support low-power users such as ground handsets. At the same time, because the geostationary orbit satellite orbit has an inclination angle of 0 degrees, it cannot cover the polar regions, and the communication angle in high latitude regions is small, and the communication quality is difficult to...
