基于无线数据的高精度超宽带定位方法综述

Overview of High Precision UWB Location Methods Based on Wireless Data

基于目前GPS、北斗定位系统因建筑物阻隔等因素而在室内定位效果不佳的情况,以超宽带(UWB)、WiFi、蓝牙等为基础的室内定位技术得到了广泛应用和快速发展,其中的UWB技术因其传输速率高、功耗小、抗干扰能力强和精度高等特点更是占据着重要的地位。从室内定位技术、UWB定位方法和UWB硬件设施3个角度对室内定位技术进行了分析和总结,针对构建室内定位系统,特别是以UWB技术为代表的高精度室内定位技术方法进行综合论述,并探讨了未来高精度UWB室内定位技术的发展方向。

Based on the poor effect of the current GPS and Beidou positioning system in indoor positioning due to building barriers and other factors,indoor positioning technology based on ultra-wideband(UWB),WiFi,Bluetooth and other technologies has been widely used and developed rapidly.Among them,UWB technology occupies a pivotal position because of its high transmission rate,low power consumption,strong anti-interference ability and high precision.The indoor positioning technology from three angles are analyzed and summarized,i.e.indoor positioning technology,UWB positioning method and UWB hardware facilities.The construction of indoor positioning system is comprehensively discussed,especially the high-precision indoor positioning technology represented by UWB technology,and the development direction of high-precision UWB indoor positioning technology in the future is discussed.
