| 摘 要： | 惯性/卫星组合导航系统在信息融合过程中,需要以运动载体姿态角速度构成误差运动状态矩阵。但一般情况下惯导平台无法输出运动载体的姿态角速度。文中分析了惯导平台框架角与载体姿态角的关系,结合硬件改造与数据处理方法,从惯导平台输出量中提取了运动载体的姿态角速度,完成了惯性/卫星组合导航系统半实物仿真试验。

| Abstract: | Attitude angular velocity of moving carrier of INS/GNSS integrated navigation system is adapted to construct error dynamic equation state matrix during information fusion process. The problem is that it is commonly unable for inertia platform to output attitude angular velocity of moving carrier. The relationship between frame angular and carrier attitude angular of inertia platform is analyzed , and the hardware reforming and data processing are adapted to extract attitude angular velocity out of inertia platform, and the semi-physical simulation experiment of INS/GNSS integrated navigation system is accomplished. |
