摘　　要：陀螺壳体旋转法监控技术是一项用于提高平台系统精度并减少陀螺漂移影响的重要技术.本文详细阐述了系统结构特性、基本工作原理、机械编排与稳定回路;深入研究旋转平台转速的选取方法并进行了系统误差分析;经解算得到典型情况下旋转壳体的转速.结果表明:采用陀螺壳体旋转法监控技术可以有效地调制陀螺漂移、理论上提高陀螺仪的精度2～3个数量级,从而使平台罗经系统精度得到很大的提高.Gyro case rotation monitoring is an important technique used to improve the system accuracy and to decrease the gyro drift in a stabilized gyro compass.The structural features,basic operating principle,signal flow and stabilized loop of the system were described in detail;the ways of selecting rotational speeds were further studied;an error analysis was run for the system;and the rotational speed of a gyro case under typical conditions was established through calculation.It is concluded from the results and discussions that the gyro case rotation monitoring technique can be used to effectively control the gyro drift and improve the accurary of a gyroscope by 2 or 3 orders of magnitude.
