摘　　要：设计并建成了集中差分式ＧＰＳ（ＧｌｏｂａｌＰｏｓｉｔｉｏｎｉｎｇ Ｓｙｓｔｅｍ ）车辆监控系统，研究并实现了应用在ＧＰＳ位置差分和车辆定位中的集中差方算法和卡尔曼（Ｋａｌｍ ａｎ）滤波，完成了系统的单点静态定位试验和实车试验。试验结果表明，该系统与其它ＧＰＳ差分定位系统相比，所用硬件设备较少，具有较高的性能价格比和较强的灵活性，其定位精度能够满足一般车辆监控系统的要求，具有广阔的应用前景。In this paper,Centralization DGPS vehicle m onitoring system is designed and constructed.The algorithm ofcentralization differentialand Kalm an filterused in GPSposition differentialand vehicle positioning are studied and accom plished.And the tests ofsingle pointstationary positioning and vehicle m onitoring are also carried out.The tests show thatthe system used less hardware than those ofthe other differentialsystem s,and has greater perform ance-costratio and flexibility,its positioning precision can m eetthe needs ofthe com m on vehicle m onitoring system .The system hasbroad application prospects.
