Abstract

The application provides a large-size satellite formation design method and system based on a parallel satellite array, and relates to the technical field of satellite display. The parallel satellite array comprises a plurality of relatively annular orbiting tracks arranged in parallel. The annular orbiting track is projected in the xy plane of the LVLH coordinate system. The projection track is composed of a projection ellipse and a projection circle. The projection circle appears and becomes larger as the size of the annular orbiting track increases. According to the diameter of the projection circle, the orbit parameter of the virtual main star, the configuration parameter of the slave star and the constructed orbit root number difference model between the slave star and the virtual main star, the orbit parameter of the slave star is determined to realize the slave star formation. In the case that the formation size is significantly increased, the position deviation of each satellite can be effectively reduced, and the accuracy of the formation array is ensured.
