A Satellite Constellation Orbit Design Method for Distributed Co-orbit Flight of Satellites in Geosynchronous Orbit

Abstract

The invention relates to a satellite group orbit design method for geostationary orbit satellite distributed co-orbital flight. The method includes the following steps that: the position relationship model of a reference satellite and orbiting satellites is built; an orbiting satellite orbit model is built through using the position relationship model; the number of orbiting satellite orbits is calculated according to orbiting satellite orbit requirements; and the number of orbiting satellite group orbits is generated according to the number of the orbiting satellite orbits. Relative distance fluctuations of the orbiting satellite group orbits designed by using the method of the present invention and the reference satellite is small; the azimuth angle, elevation angle and distance relationships of the orbiting satellites and the reference satellite meet multi-satellite co-orbital spacing design requirements; the azimuth angles, elevation angles and distances of adjacent orbiting satellites satisfy inter-satellite link acquisition and tracking design requirements; defects such as weak function, poor anti-interference ability, unfavorability to miniaturization of a single-satellite node condition can be eliminated; and the orbiting satellites and the reference satellite collaborate with each other, and therefore, the anti-destruction ability and self-organizing ability of a system are improved.

Description

technical field [0001] The invention relates to the technical field of spacecraft orbital dynamics and control, in particular to a satellite group orbit design method for distributed co-orbital flight around geosynchronous orbit satellites. Background technique [0002] Multi-satellite co-orbit refers to a satellite system that is composed of multiple small satellites that are densely distributed in space and work in a coordinated manner to achieve a specific function. Due to the adoption of the multi-satellite collaborative working method, the multi-satellite co-orbit mechanism has obvious advantages in the following aspects: First, the tasks completed by a single satellite in the past are distributed to each satellite in the constellation to form a large "Virtual satellite" to complete the tasks completed by a single large satellite, greatly improving the survivability of the system; second, multiple small satellites work together to achieve more functions, such as coopera...

Problems solved by technology

The above methods are all designed for distributed orbits of low-orbit remote sensing satellites, and do not need to consider orbit resources. Considering the particularity of geosynchronous orbit satellite orbits and scarcity of orbit resources, it is necessary to ensure the stability of the constellation structure and ensure Flying satellites cannot interfere with other satellites already in orbit, and the existing methods are difficult to meet the multi-satellite co-orbit configuration design of the geosynchronous orbit satellite group
