Embodiment Construction

[0073] The method and system for determining the attitude of a spacecraft based on inter-satellite measurement information proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become apparent from the following description and claims. It should be noted that the accompanying drawings are all in a very simplified form and in inaccurate scales, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the present invention.

[0074] The inventor found that in the existing literature, some literatures have studied the GPS-like multi-spacecraft cooperative navigation of cooperative targets through inter-satellite communication, and some literatures have used gyroscope and inter-satellite measurement information for non-cooperative targets. Combined with filtering methods, the relative navigation...

Abstract

The invention provides a spacecraft attitude determination method and system based on inter-satellite measurement information, including: measuring the orbit information of the local star and the target star, obtaining the relative position information between the local star and the target star; The parameters related to the line-of-sight axis alignment of the equipment are converted into inter-satellite vectors representing the attitude characteristics of the spacecraft; the measurement information of the attitude sensor on the local star is directly obtained; the relative position information, the inter-satellite The vector and the measurement information are fused to form spacecraft attitude information, and the three-axis attitude of the spacecraft is determined according to the spacecraft attitude information.

Description

technical field [0001] The invention relates to the technical field of spacecraft attitude determination, in particular to a spacecraft attitude determination method and system based on inter-satellite measurement information. Background technique [0002] In the existing literature, some literatures have studied the GPS-like multi-spacecraft cooperative navigation of cooperative targets through inter-satellite communication, and some literatures have used gyroscope and inter-satellite measurement information, combined with filtering methods, for non-cooperative targets. Relative navigation and relative attitude determination of non-cooperative targets are studied. It can be seen that the existing literatures focus on how to use the inter-satellite measurement information and other sensor information on the satellite to determine the relative attitude between the local star and the target star, but ignore the inter-satellite measurement information. Like other sensor inform...
