摘要
以主惯导和子惯导的速度差和角速度差作为观测量,设计速度加角速度匹配传递对准方法。推导了速度加角速度匹配微分方程,建立了速度加角速度匹配的线性滤波模型。速度加角速度匹配传递对准方法作为计算参数匹配法和测量参数匹配法的结合,比较传统的速度匹配传递对准方法利用了更多的观测信息,因此,对方位的估计精度高,估计时间短。
The transfer alignment of velocity plus angular rate match uses the differences between the master inertial navigation and slave inertial navigation as the measurements. The velocity and angular rate difference equations are deduced, and the liner filter model for velocity plus angular rate match is constructed. The velocity plus angular rate match method combines the advantages of the calculation parameter match and measurement parameter match. Compared to the conventional velocity match method, this method utilizes more measurement information. So the yaw estimation accuracy is better and the estimation duration is rapider than conventional one.
