摘要

差分全球定位系统（DGPS）是一种精确的定位系统

但在室内或有障碍物的情况下

其定位精度很低甚至不能进行定位。超宽带（UWB）定位系统在室内有很高的定位精度

但受其测量范围的影响

不适合室外定位。将DGPS和UWB结合定位

利用Kalman滤波器对UWB非视距误差（NLOS）进行消除

采用粒子滤波器对不同传感器进行数据融合

并使用GPRS通信模块进行无线数据传输。实验表明:该方法能够使系统整体定位精度提高19%

既能满足室内外无缝定位

又具有很高的定位精度。

Abstract

Differential global positioning system（DGPS）is a precise positioning system

but in some circumstances

such as obstacles existence or indoor

the positioning precision is quite low

even cannot located.Ultra wide band（UWB） is a high precision positioning system in indoor positioning

but it is not suitable for outdoor positioning for the limited measurement range.A combination of DGPS and UWB positioning system is introduced

using the method of Kalman filter to eliminate non line of sight（NLOS）errors

and using particle filters to resolve data fusion derived from different sensor.And the wireless data is transmitted by the GPRS communication module.Experimental results show that the method enables the system to improve the overall positioning precision of 19%

not only meets the indoor and outdoor seamless positioning

but also has high positioning precision.
