Polar orbit constellation GEO interference avoidance method based on polar orbit constellation attitude bias

Abstract

The invention discloses a polar orbit constellation GEO interference avoidance method based on polar orbit satellite attitude bias. Constellation coverage continuity is not considered in a current polar orbit constellation GEO interference avoidance method. In order to solve the problems that the polar orbit constellation service is possibly interrupted, the frequency interference avoidance of theGEO satellite is realized through the attitude continuous bias of the polar orbit constellation satellite, and meanwhile, the polar orbit constellation coverage is continuous and the coverage overlapping area margin is maximum through the optimization of the satellite attitude bias rule, so that the polar orbit constellation coverage continuity is ensured.

Description

Technical field [0001] The invention relates to a polar orbit constellation GEO interference avoidance method based on polar orbit constellation attitude bias, belonging to the field of satellite interference avoidance. Background technique [0002] Starting from the space age, satellite communication has been an important application direction of space technology. With the development of satellite technology, human demand for high-speed network access services on a global scale is increasing. Humans have used geostationary orbit (GEO) satellites to provide satellite communication services for decades. Satellites in geostationary orbit are characterized by zero inclination and the orbital period consistent with the rotation period of the earth. Therefore, the position of the satellite is almost stationary for the ground station. This excellent feature makes the use of GEO satellite communication to be developed by leaps and bounds. However, with the continuous development of s...

Problems solved by technology

[0003] Currently, Oneweb has proposed a GEO frequency interference avoidance strategy based on satellite pitching attitude offset (patent application number: PCT / IB2015 / 002383), which realizes low-orbit communication constellation through continuous attitude offset of polar-orbit constellation satellites Avoiding frequency interference with GEO satellites, but it does not give specific implementation methods and technical approaches, does not introduce the method of obtaining satellite attitude offset laws, cannot guarantee the continuity of coverage of polar orbiting satellites, and is not conducive to the development of polar orbiting constellations Engineering realization
