摘要
随着卫星定位技术(Global Positioning System,GPS)在室外定位中的深入应用,人们在室外环境下对位置服务(Location Based Service,LBS)愈加依赖,而室内环境中的定位技术还有待发展。本文主要研究了目前室内环境下的主流定位技术及其解决方案,并将其优缺点进行了对比分析,最终给出选择超宽带定位技术的原因。同时,还分析了超宽带定位技术的基本原理及最终选择TDOA算法的原因,并给出求解其后续非线性方程组的建议。简述了在室内环境下影响移动目标精准定位的主要因素,其中,因为非视距传播最能影响信号传播,所以针对降低其对精度的影响力进行了相关算法介绍。
With the in-depth application of satellite positioning technology in outdoor positioning,people have become increasingly dependent on Location Based Service(LBS)in outdoor environment,while the positioning technology in indoor environment still needs to be developed.This paper mainly aims at indoor environment,summarizes the current mainstream positioning technology and its solutions,and compares its advantages and disadvantages,finally gives the reasons for choosing ultra-wideband positioning technology.At the same time,the basic principle of ultra-wideband positioning technology and the reason of choosing TDOA algorithm are analyzed,and the suggestions of solving its nonlinear equations are given.This paper briefly discusses the main factors that affect the precise positioning of moving target in indoor environment,among which,because the non-line-of-sight propagation can best affect the signal propagation,the corresponding algorithm is introduced to reduce its influence on precision.
