摘    要:针对交会对接最终逼近段相对位姿测量,提出了惯性/视觉组合相对导航算法。基于对接航天器相对运动模型,利用追踪航天器上惯性测量单元(IMU)获取两航天器间的相对运动信息作为短期参考,以电荷耦合器件(CCD)视觉测量作为长期参考,综合姿态四元数运动学方程,分别建立了姿态滤波器和位置滤波器。仿真结果表明算法可行且有效,并仿真分析了导航精度。

关 键 词:组合相对导航  IMU  四元数  卡尔曼滤波

Abstract:An integrated relative navigation algorithm based on inertial measurement unit(IMU) and charge coupled device(CCD) was put forward for the final approach phase of rendezvous and docking in this paper.Based on the relative movement model and attitude quaternion kinematics equation,attitude filter and position filter were established,with the relative movement information obtained by IMU as short-term reference and CCD measurement as long-term reference.The attitude filter and position filter integrated with ...
