摘要
从机理上分析了型号武器在射前精度检查时，陀螺漂移值偏大的根本原因。说明大地基准方位角的测量偏差会对射前精度检查造成影响，并通过数据分析得到验证。
The gyroscope drifting value is bigger when checking the accuracy of weapons before launch. The basic cause of this phenomenon is analysed on mechanism . Then the measured deviation of the baseline azimuth would have inflence on the accuracy checking before launch is explained and verified by data analysis.
