摘要
介绍了一种无人机导航算法的设计方案和原理,分析了GPS/INS组合系统中误差、偏差来源,针对系统存在的误差,采取差分测量以及自适应滤波算法,并对设硬件系统的误差进行仿真,证实了设计方案可以提高系统的精度。
The scheme and principle of the navigation system of UAV is introduced.Analysis the source of error and deviation in the combined navigation of GPS/INS.For the error being in system, adopt difference measurement and adaptive filter.The error of system by simulation, it shows that the design can improve the accuracy of system.
