摘要

惯性导航系统(INS)可独立测量车辆的位置、速度和姿态(PVA),为其向目标导航。由于惯性导航系统是一种死飞系统,因此需要精确的初始化来提供导航(PVA)解决方案。在空射战术导弹中,飞机导航系统(主 INS)的信息用于精确初始化导弹 INS(从 INS)。在当今的作战行动中,需要利用飞机导航信息在最短时间内完成从属 INS 初始化,从而实现快速转移对准。转移对准包括首先初始化导弹 INS,并利用导弹 IMU 的速率和加速度建立导航解(PVA),然后使用卡尔曼滤波器估计从属 INS 和主 INS 之间的误差。该方法的仿真结果表明,基于飞机的姿态信息和飞机起飞时的自然机动,战术导弹 INS 可以在很短的时间内对准到可接受的精度。

Rapid and Accurate INS Transfer Alignment for Air Launched Tactical Missile Using Kalman Filter
An Inertial Navigation System (INS) independently measures the Position, Velocity, and Attitude (PVA) of thevehicle to navigate it towards the target. Since INS is a dead-reckoning system, it requires accurate initialization toprovide the navigation (PVA) solution. In the case of an air-launched tactical missile, the aircraft navigation system(Master INS) information is used to initialize accurately the missile INS (Slave INS). Rapid transfer alignment isneeded in today’s combat operation to converge slave INS initialization in the shortest possible time using aircraftnavigation information. The transfer alignment consists of first initializing the missile INS and establishing anavigation solution (PVA) using the missile IMU rates and accelerations, then a Kalman filter is used to, estimatethe errors between the Slave INS and Master INS. The proposed method’s simulation results show that a tacticalmissile INS can be aligned to an acceptable accuracy in a very short time based on the aircraft’s attitude information and with natural maneuvers experienced during aircraft take-off.
