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

Embodiment Construction

[0051] The normal operation process of polar orbiting satellites is as follows: figure 1 as shown, figure 1 Among them, 1 is the polar orbit satellite orbit, 2 is the earth, 3 is the polar orbit satellite, 4 is the equatorial plane, 5 is the descending node, and 6 is the ascending node. During normal operation, the polar-orbiting satellites periodically cross the equatorial plane along the polar-orbiting satellite orbit. A polar-orbit constellation GEO interference avoidance method based on polar-orbit satellite attitude offset described in this patent realizes the frequency interference avoidance of GEO satellites through the continuous attitude offset of polar-orbit constellation satellites, and at the same time optimizes the law of satellite attitude offset , so that the coverage of the polar orbit constellation is continuous and the coverage overlap margin is the largest, so as to ensure the continuity of the coverage of the polar orbit constellation, as shown in Figure 9...

Abstract

A polar-orbit constellation GEO interference avoidance method based on polar-orbit satellite attitude offset. Aiming at the problem that the current polar-orbit constellation GEO interference avoidance method does not consider the continuity of constellation coverage, which may lead to the interruption of polar-orbit constellation services, through polar-orbit The continuous attitude offset of constellation satellites realizes the frequency interference avoidance of GEO satellites. At the same time, through the optimization of satellite attitude offset rules, the coverage of polar orbit constellations is continuous and the coverage overlap margin is the largest, thereby ensuring the continuity of polar orbit constellation coverage.

Description

technical field [0001] The invention relates to a polar orbit constellation GEO interference avoidance method based on polar orbit constellation attitude offset, and belongs to the field of satellite interference avoidance. Background technique [0002] Since the space age, satellite communication has been an important application direction of space technology. With the development of satellite technology, human beings' demand for high-speed network access services around the world continues to grow. Humans have used geostationary orbit (GEO) satellites to provide satellite communication services for decades. Satellites in geostationary orbit are characterized by zero inclination and an orbital period that coincides with the Earth's rotation period. Therefore, for the ground station, the position of the satellite is almost static, and this excellent feature makes the use of GEO satellite communication develop rapidly. However, with the continuous development of society, t...
