本文应用现代控制理论中可观测度的概念来分析姿态确定精度。建立了测量系统精度和可观测度之间的解析关系，并表明可观测度可以作为选择最佳测量模型的数学特征。此外，冗余测量模型的研究成果已推广到通用测量系统，为实际设计中构建最佳测量模型提供理论依据。
In this paper the concept of degree of observability in modern control theory is applied to the ananlysis of attitude determination accuracy. The analytical relationship between accuracy and degree of observability of a measurement system has been found and it is shown that the degree of observability can be used as mathematical features for selecting the best measurement model. In addition, the results about redundant measurement model have been extended to general measurement system and provide theoretical basis for constructing the best measurement model in practical design.
