| 摘 要： | 结合稳瞄系统和自主寻北定位定向系统的特点,研究了车载稳瞄/惯导一体化技术,阐述了车载稳瞄/惯导一体化系统的工作原理,进行了稳瞄/惯导一体化系统的总体设计。在随机调转的稳瞄平台上布置陀螺仪和加速度计组成惯性测量组件(IMU),IMU同时向稳瞄系统和导航系统提供信号,稳瞄平台在运动中完成瞄准的同时,解算出平台的姿态矩阵,通过平台环架转动夹角的角度量,获得车体姿态矩阵,以此得出车体的加速度在导航坐标系上的分量,最终完成航迹推算。通过跑车试验表明,稳瞄/惯导一体化算法是正确与实用的。

| Abstract: | Combining with the characteristics of the stable sighting system and the north-finding system,the integration of the stable sighting and the inertial navigation system (SS-INS) for land vehicle is studied,and the operating principle and the design of the SS-INS are presented.Gyros and accelerometers are fixed on a stabilized platform to form an inertial measurement unit(IMU),in which the platform can randomly turnaround in azimuth and level.The IMU provides signals for the stable sighting system (i.e.the se... |
