摘要
对舰船应用环境下的快速传递对准技术进行了研究.推导了主惯导与子惯导之间姿态之差的动态方程,采用Kalman滤波技术估计子惯导系统的安装误差角.设计了在不依赖舰船有意识机动情况下而仅仅依靠外界风浪的干扰就能实施快速传递对准的方法.仿真结果表明,在10s内,子惯导系统安装误差角估计可以达到优于1mrad的精度.
Studies the rapid transfer alignment technique in marine environment. Dynamic equation of attitude error between the master and slave inertial navigation systems is presented. Kalman filter technique is adopted under the condition of no maneuvering, depending simply on random disturbances from wind and wave. The rapid transfer alignment process works well. The final simulation result shows that the slave inertial system's misalignment can reach an anticipated precision in a short time.
