摘要
针对无人水下航行器自主导航需求,文中设计由多普勒计程仪(DVL)、深度计、电子罗盘(ECP)和低成本惯性量测单元(IMU)组成的航位推算导航系统,提出一种DVL自主导航方法。该方法通过传感器一体化集成克服安装误差和时间异步问题,采用ECP/IMU融合方案获取高频姿态参数,在此基础上,制定DVL异常数据处理、高动态误差修正以及全球导航卫星系统辅助策略。所提出的方法在“海为一号”自主水下航行器上得到应用,试验结果表明自主导航定位精度约为航程的1.5%(圆概率误差),可以为相关研究和应用提供参考。
In response to the requirement for autonomous navigation capability of unmanned undersea vehicles,a dead-reckoning navigation system composed of a Doppler velocity log(DVL),a pressure sensor,an electronic compass(ECP),and alow-cost inertial measurement unit(IMU)is designed in this study,and a DVL-based autonomous navigation method isdeveloped.In the proposed method,a sensor integration scheme is implemented to overcome the installation error and timeasynchrony.An ECP/IMU fusion scheme is developed for high-frequency attitude parameters.On this basis,the strategies forthe elimination of DVL abnormal data,the correction of DVL high dynamic errors and the assistance of global navigationsatellite system are formulated.The proposed method is applied on the“Haiwei 1”autonomous undersea vehicle(AUV).Thefiled experiments of“Haiwei 1”AUV indicate that the positioning accuracy of the autonomous navigation corresponds toapproximately 1.5%(circular error probable)of the distance traveled,which can serve as a reference for related researches andapplications.
