船用捷联惯导系统解析粗对准的误差分析

Error Analysis of Analytic Rough Alignment for Marine SDINS

讨论了两种船用捷联惯性导航系统（ＳＤＩＮＳ） 静基座解析粗对准的方法，选择不同的参考矢量求解变换矩阵，将导致不同的失准角误差。结果对比给出了形象的说明。

This paper discusses two methods of analytic rough alignment for marine SDINS on stationary base.During solving the transformation matrix, choosing different reference vectors will result in different misalignment angles.The computation results give a visual demonstration.
