摘要:

高动态复杂环境下的无人机移动定位中,捷联式惯性导航(SINS)系统存在误差漂移,全球定位系统(GPS)可能发生信号失锁等问题。本文针对无人机定位方法进行研究,基于其速度信息和位置信息,给出了一套无人机测算目标物精准位置信息的方法。该方法结合GPS定位技术与SINS定位技术,采用H滤波算法对量测数据进行融合,使两定位技术优势互补,进一步降低了定位误差,特别适合于长时间导航定位。试验结果表明:将H滤波引入组合式导航定位时,既能提高滤波的收敛性,又可以保持较高的定位精度。

Abstract:

In the high dynamic complex environments of UAV mobile positioning,the SINS system may have error drift and the GPS signal may interrupted.Study on rotorcraft UAV positioning,a method for measuring precise position information of target by UAV based on the velocity and position information is given.Using H Filter algorithm for fusion of measurement data,the method has the merits of GPS and SINS positioning technology and further reduces the positioning error,especially suitable for long time navigation.Experiment results show that:When H filtering is introduced into the combined navigation and positioning,that can improve the convergence of the filter,but also to maintain high accuracy of positioning.

Key words: UAV, positioning, H filter, error, simulation
