【摘要】 提出了利用经纬仪观测恒星解算惯导姿态角误差的方法,并建立了数学模型。在进行理论精度分析的基础上,利用实测数据对惯导姿态角误差进行了试解算;同时通过长时间跟踪恒星记录的数据,对惯导姿态角的动态误差特性进行了分析。结果证明,该方法可以作为评估惯导动态姿态精度的一种有效手段。
【Abstract】 In this paper,a method of attitude errors evaluation in inertial navigation system has been introduced by using the survey of fixed star based on theodolite,and the mathematical details for this efficient idea are put forward.The attitude errors are calculated through using the theodolite survey data.By using the data of survey one of the fixed star for a long time,the dynamic errors of the attitude have been analyzed.All the results show the accuracy and efficiency of the proposed method.
【Key words】 theodilite; survey of fixed star; INS; attitude angle; errors;
