| 摘 要： | 惯性导航系统受到陀螺和加速度计误差的影响,导航定位误差随着时间累积甚至发散.解决惯导系统误差累积的有效方法是采用组合导航系统.随着其他导航系统性能的不断提高,以惯导系统为中心,其他导航系统为辅助的组合导航系统是目前的研究热点.给出了一种以惯导系统为主,GPS和磁航向传感器为辅的多传感器组合导航系统,并对该组合导航系统进行了仿真研究.通过对仿真结果进行分析,验证了所提出的组合导航系统能够满足无人机导航任务的要求并且具有良好的稳定性.

| Abstract: | The orientation error of Inertial Navigation System will be cumulated and sometimes even spread in the course of time because of the error from gyroscope and accelerometer. One effective way for resolving this problem is using the Integrated Navigation System. With the improvement of the performance of other navigation systems,the integrated navigation system which combines the inertial system as main part with other systems as assistant part is becoming a research hotspot. The paper gives a method for buil... |
