基于UWB的高精度室内定位系统

High Precision Indoor Positioning System Based On UWB

在室内环境下,全球定位系统(GPS)以及其他定位技术受许多不可抗拒的因素影响无法对用户进行精准定位。然而,从移动互联到物联网,位置是一个基础的不可或缺的信息,对于精细化的行业应用需求来说,越精准的定位信息越能带来更高的价值。所以,为向群众提供无所不在的位置服务,对UWB(Ultra Wide Band)技术与TOA(Time of Arrival)的定位算法进行了研究,并设计出了一款基于UWB技术的高精度室内定位系统。最后,通过试验验证了系统的精准度能达到厘米级,且实时性较好。

In an indoor setting, Global Positioning System and other positioning technology can not accurately locate users due to many irresistible factors. However, from the mobile Internet to the Internet of things, location is a basic and indispensable information. For the requirements of refined industrial applications, the more accurate precision location information can bring the higher value. As a result, In order to provide ubiquitous location service to the public, this paper researched Ultra Wide Band technology and Time of Arrival positioning algorithm, and then designed a high-precision indoor positioning system based on Ultra Wide Band technology. In the end, it is proved by experiments that the accuracy of the system can reach the centimeter level, and the real-time performance of system is good.
