摘要: 导航恒星作为天文导航系统定姿的基础信息源,其空间分布对天文导航系统定姿性能存在较大影响。为有效分析天文定姿误差特性,基于天文定姿观测基本原理,采用多矢量天文定姿方法,推导建立了天文定姿误差模型,基于该模型分析了影响天文定姿性能的关键因素,并给出用于评价定姿性能优劣的误差权系数定义。以多矢量定姿中的三星观测定姿为例,采用仿真验证了所建立的基于恒星几何分布的天文定姿误差模型的正确性,该误差模型能够有效反映天文定姿的误差特性规律,为分析天文定姿性能提供了理论依据。

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.
