| 摘 要： | 为了分析捷联惯性导航系统的误差特性,试验中往往利用另一精密惯性基准为其提供实时的标准解。由于安装捷联惯导系统的一体性支架存在着加工误差以及两套惯性导航系统之间存在着安装误差。因此,两套惯性导航系纯的测量坐标系难以完全重合,它们之间存在一个坐标转换矩阵。本文根据技术要求设计试验步骤,利用重力场环境标定它们之间的这一转换矩阵,从而建立标准解与捷联惯导系统测量结果的数据联系。

| Abstract: | In the experiment, in behalf of analyzing the errors characteristic of the strapdown inertial naviga-tion system, the real-time standard solution is given by a precision inertial navigation system. Because of the mounting error of two sets of inertial measuring system and the outfitter error of installation bracket, the con-version matrix is existed with two measurement coordinate system of two sets of inertial measuring system. In this paper, the test step is designed by using gravity vector to calculate the conversion matrix. |
