| 摘 要： | 用于传递对准的测量参数匹配法极大地受限于舰船所处海况，为解决这一问题，提出了姿态加角速度匹配法。在三种典型的海况下，对这一传递对准方法中舰船甲板变形和陀螺常值漂移进行了Kalman滤波估计及精度分析，并对陀螺漂移标定的可行性进行了深入的分析。研究结果表明，姿态加角速度匹配法具有稳健的对准精度和快速性，陀螺漂移的标定依赖于舰船甲板动态变形的大小。

| Abstract: | The transfer alignment methods with measurement parameters are limited by sea condition,so an attitude plus angular rate matching method is put forward.In this paper,the deformation of ship's deck and the constant drift of gyros under three typical sea conditions is estimated using this method with Kalman filter,and the estimate precision is interpreted.The feasibility of the calibration of gyro drift is analyzed in detail as well.Study results show that higher precision and shorter response time with robust is obtained.The calibration of gyro drift is depended on the magnitude of dynamic deformation of ship's deck.. |
