摘　　要：针对旋转惯导系统导航性能受陀螺漂移调制特性影响的问题,以双轴旋转惯导系统为对象,推导了双轴依次旋转方式的漂移调制特性;通过傅里叶级数变换,提取了调制后陀螺漂移的关键分量;通过惯导误差方程求解和分析不同转、停时间条件下的定位误差特性,确定了优化的双轴转位方案。计算机比对仿真表明:优化的转位方案能有效提高双轴旋转捷联惯导的导航定位性能。Aiming at problem of modulation result of gyro drift affects the navigation characteristics of rotation inertial navigation system （SINS）. Gyro drift modulation characteristic caused by rotation device of double-axis rotation SINS is deduced. By means of Fourier transform, the crucial component of gyro drift after modulation is extracted. By inertial navigation error expression, navigation error characteristic of conditions with various rotation and stop time is solved and analyzed, and the optimized rotation scheme is confirmed. Computer comparison simulation result shows that the optimized scheme can enhance the position characteristics effectively.
