摘要: 捷联陀螺罗经的航向和姿态测量会受载体的动态运动影响而产生较大误差。本文在对载体运动加速度误差传递机理分析的基础上,基于惯导短时间不发散的思想,提出了一种动态下捷联罗经姿态测量误差补偿方法。当载体处于动态运动时,采用阶段性重置的短时惯导算法持续计算导航系坐标下的运动加速度,对罗经回路中受到干扰的加速度计数据进行补偿,进而降低动态测量误差。试验结果表明,动态下补偿后的航向角均方根误差(RMSE)为0.792°,俯仰角和横滚角均小于0.030°,有效提升了罗经系统的动态姿态测量性能。

Abstract: The heading and attitude measurement of the strapdown gyrocompass will be greatly affected by the dynamic motion of the carrier,resulting in significant errors.Based on the analysis of the transmission mechanism of carrier motion acceleration error,a dynamic compensation method for attitude measurement error of gyrocompass is proposed using the idea of inertial navigation without divergence in a short period of time.When the carrier is in dynamic motion,a short-term inertial navigation algorithm with periodic reset is used to continuously calculate the motion acceleration in the navigation system,compensate for the disturbed accelerometer data in the compass loop,and thereby reduce dynamic measurement errors.The experimental results show that the root mean square error (RMSE) of the heading angle after dynamic compensation is 0.792°,and the pitch angle and roll angle are less than 0.030°,effectively improving the dynamic attitude measurement performance of the gyrocompass system.

Key words: strapdown gyrocompass, inertial navigation, dynamic maneuver, motion alignment, error compensation
