Abstract

An embodiment of the present invention discloses a method for realizing the sun transit forecast of the inter-satellite link by the ground operation control system. The method makes full use of the sun-earth-satellite space relationship, and considers the shadow of the earth to complete the sun transit forecast. The method can Quickly judge whether the inter-satellite link is affected by the solar transit, and calculate the transmitting end where the solar transit occurs simultaneously under the four conditions of the same link in the same orbit, the same link in different orbits, the different links in the same orbit, and the different links in different orbits in the constellation system The number of satellites and the corresponding duration of the sun transit assist the ground operation control system in formulating the sun transit avoidance strategy and inter-satellite dynamic routing allocation strategy.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method for realizing inter-satellite link sun transit forecasting by a ground operation control system. Background technique [0002] In a large satellite constellation, the communication between satellites on the same orbital plane or adjacent different orbital planes is called inter-satellite link. The solar transit phenomenon refers to a phenomenon that when the link direction of the laser communication between adjacent satellites in the satellite constellation is in a linear relationship against the direction of the sun, the electromagnetic wave of sunlight will interfere with the communication signal and affect the life of the laser communication equipment. [0003] The orbit configuration of the satellite constellation is Walker type, which is a constellation form evenly distributed in space. In this constellation configuration, the difference in right as...
