一种惯性测姿装置的校准方法

A Method of Inertial Attitude Measuring Device Calibration

根据惯性测姿装置的基本原理和组成,将装置的姿态角引出到立方镜的工作面上,提出了一种利用电子经纬仪进行三维姿态角的校准方法,该方法通过电子经纬仪分别对立方镜的工作面进行测量,再根据姿态角的定义进行角度转换,从而实现对惯性测姿装置的校准。此外,利用惯性测姿装置进行试验,验证了该校准方法的可行性,并对校准结果的测量不确定度进行评定。

Based on the principle and composition of inertial attitude measuring device,the attitude angles of the device are transferred to the working face of the cubic mirror.The calibration methods,which are used to calibrate threedimensional attitude angles,are brought forward.The working faces of the cubic mirror are measured by the electronic theodolites.Base on the definition of the attitude angles,the angles are converted.The calibration of inertial attitude measuring device is realized.The experimentation,which aims at the inertial attitude measuring device,is put forward.The feasibility of these calibration methods is demonstrated by experimental cases.Finally,the measurement uncertainties are evaluated in the calibration methods.
