Example Embodiment

[0028] The present invention will be further described below in conjunction with the embodiments of the drawings.

[0029] The present invention provides a relative tracking and position transfer control method based on relative orbit elements. The method includes two parts: long-term tracking control near a given tracking point and position transfer control between different tracking points.

[0030] 1. Relative flight control based on relative orbit elements

[0031] Including: Controlling the size of the accompanying flight ellipse in the orbital plane based on the relative orbital element control law, and controlling the drift speed relative to the center point of the accompanying flight ellipse to maintain it near the set accompanying flight point; and the relative accompanying flight outside the orbital plane Control, that is, control the relative motion amplitude in the normal direction of the orbit based on the relative orbit element control law, so that the smaller the norma...

Abstract

The invention discloses a relative formation flying and position transfer controlling method based on a relative orbit element. The method comprises long-term formation flying control near a given formation flying point and position transfer control among different formation flying points. Compared with the prior art, the relative formation flying and position transfer controlling method based on the relative orbit element has the advantages of being capable of achieving the control of formation flying, approaching and retreating based on the relative orbit element, achieving the establishment and maintenance of a relative formation flying state between two spacecrafts, and providing conditions for the close space missions.

Description

technical field [0001] The invention relates to satellite guidance, navigation and control technology, in particular to the accompanying flight and formation flight control technology among multiple spacecraft. Background technique [0002] In recent years, small satellite technology has been rapidly developed and applied, providing a wider range of applications in the space field. It is a trend in the development of space technology in the future that multiple small satellites form a formation in a certain configuration to replace the original single complex satellite to complete the task. Compared with the traditional single complex large satellite, the "virtual satellite" composed of multiple small satellites through formation can replace or even surpass the original single complex large satellite in function, and has low cost, strong adaptability, and high reliability Sex and other advantages. [0003] The simplest formation flight technology is to keep two satellites ...
