A method for analyzing the interference of non-geostationary orbit satellites to geostationary orbit satellites

Abstract

The invention relates to a method for analyzing interference of a non-stationary orbit satellite on a stationary orbit satellite. The method comprises the following steps: determining downlink equivalent power flux density of the non-stationary orbit satellites to a stationary orbit satellite earth station according to positions of the non-stationary orbit satellites with maximum interference to the stationary orbit satellites; and determining the uplink equivalent power flux density of the non-geostationary orbit satellite earth station to the stationary orbit satellite according to the position of the stationary orbit satellite with the maximum interference of the non-geostationary orbit satellite; further determining the interference degree of the non-stationary orbit satellite to the stationary orbit satellite, and finding the non-stationary orbit satellite corresponding to the position with the maximum interference degree. According to the method, the relation between the interference degree and the real-time states such as the position, the beam configuration, the working state and the satellite attitude of the non-stationary orbit satellite system can be established, and aninterference avoidance strategy can be conveniently given or the effectiveness of the non-stationary orbit satellite interference avoidance strategy can be conveniently verified.

technical field [0001] The invention relates to the field of satellite communication, in particular to an analysis method for interference from non-stationary orbit satellites to geostationary orbit satellites. Background technique [0002] With the development of satellite communication technology, non-geostationary orbit satellites are widely used around the world. The number of non-geostationary orbit satellites is huge, and most non-geostationary orbit satellites use overlapping frequency bands with geostationary orbit satellites. According to the Radio Regulations, satellites in non-geostationary orbit are responsible for avoiding interference with satellites in geostationary orbit. Therefore, it is necessary to analyze the interference of non-geostationary orbit satellites to geostationary orbit satellites in order to give interference avoidance strategies.
