Abstract

Abstract: As the basic element of celestial attitude determination, the geometric distribution of guide stars has a great impact on the performance of celestial navigation system. In order to analyze the error characteristics of celestial attitude determination,an error model based on basic celestial attitude determination principles is established by adopting the method of multi-vectors attitude determination, and the weighting coefficients are provided for assessment. Taking tri-star observation for example, the error model is verified by applying digital simulation. The proposed model can be used to analyze the performance of celestial attitude determination effectively, providing theoretical basis for error characteristics analysis.

Key words: control science and engineering, multi-vectors attitude determination, geometric distribution of guide stars, error model
