车辆定位系统中的信息融合方法

Information Fusion Methods for Vehicle Positioning System

采用卫星定位 -航位推算系统 (GPS -DR)和数字音频广播 -GSM移动通信系统(DAB -GSM)的融合定位系统 ,研究智能交通系统中各种先进的车辆定位技术 ,重点探讨了GPS -DR和DAB -GSM融合定位系统的原理和使用情况 ,给出了主要模型和公式 ,并对其特点进行了比较 .结果表明 ,这两种技术都能在一定程度上满足高精度和低成本的要求 ,但应用层面并不相同 ;DAB

An advanced vehicle positioning technique in the in telligent traffic system had been investigated, putting stress on the principles and applications of the positioning system which combines GPS-DR with DAB-GSM , giving its main models and computing formulae and making a comparison of its c haracteristics. The results show that, to a certain degree, both techniques meet the requirements of high precision and low cost despite their different applied fields. However, the findings in the research on DAB-GSM will certainly carve out a brilliant future in the use of DAB and GSM networks for vehicle positionin g techniques.
