摘要
为了应对航天、航海和车辆导航对导航系统的精度,提出了基于DSP的捷联惯性导航系统(SINS)/全球定位系统(GPS)/地磁组合导航系统。介绍了该组合导航的系统结构与基本原理,采用无迹卡尔曼滤波(UKF)算法完成对组合导航信息的融合,并对组合导航样机进行车载实验。试验结果表明,该组合导航系统提高了精度、计算速度和稳定性。
In order to cope with aerospace,marine and vehicle navigation precision navigation system,DSP-based inertial navigation system（ SINS） / global positioning system（ GPS） / geomagnetic integrated navigation system are presented.This paper briefly describes the system structure and the basic principle of the combination of navigation,the use of unscented Kalman filter（ UKF） algorithm to complete the integrated navigation information fusion,and car navigation prototype experiment. Experimental results show that the integrated navigation system improves the accuracy,computational speed and stability.
