| 摘 要： | 针对自主导航小车在区域行驶中的定位问题,研究了TDOA-DR组合导航定位算法。通过对基于到达时间差(TDOA)的双曲线导航原理的分析,采用了基于超声波传感器的多基站双曲线定位系统。并在此基础上,对TDOA-DR组合导航系统的结构和算法进行研究和仿真分析。仿真结果表明:TDOA-DR组合导航系统能够在区域内提供厘米级精度的连续车辆位置信息,满足区域高精度定位的需求。

| Abstract: | According to the problem of local position information for automatic guided vehicle(AGV),a TDOA-SINS integrated navigation system is researched.By analyzing the principle of hyperbolic navigation based on the time difference of arrival(TDOA),the hyperbolic navigation system,which stations are constituted of multi-ultrasonic sensors is used.Those are bases of studying the structure and the filter model of the TDOA-DR integrated navigation system.The emulation results show that the TDOA-DR can provide high-precision location information which errors are several centimeters and the demand of the region locating can be met. |
