摘　　要：GPSone定位技术,是目前世界上最先进的定位技术。它将无线网络辅助GPS定位及CDMA三角定位运算定位功能嵌入到CDMA终端芯片之中,将上述两种技术进行了有机的结合,形成了独步移动定位市场的GPSone混合定位技术。摒弃了传统定位终端所采GSM+GPS或CDMA+GPS的模式。具有盲区少,适应面宽,成本低的特点。克服了GPS在室内、地下停车场、隧道、城市高楼林立等环境下,无法定位或定位不准的弊端,提高了定位精度和定位成功率。文章首先研究了现有的多种定位技术,分析了各种定位技术的优缺点,着重分析和研究了GPS全球定位系统和基于CDMA无线蜂窝网的gpsOne定位技术,根据这两种定位技术的优缺点及系统运行成本的需求,提出了利用GPS定位技术和gpsOne定位技术进行混合定位、以GPS为主的定位数据采集方案。The GPSone positioning technique is the most advanced positioning technique now. It implants the wireless GPS position and the CDMA triangle position into the terminal CMOS chip, combines the two techniques in an organic way, and forms a mixed position technique of GPSone in the mobile market. It spurns the mode of traditional positioning terminal, and has the features of fewer blind spots, broad adaptation, and low-cost. It also overcomes the defects of non-accuracy when it is in indoor spots, in the underground parking lots, in the tunnel or in the high buildings, improves the precision and probability of position. This paper first analyzes the advantages and disadvantages of the generally used position technology, especially focuses on GPS and GPSone. According to the characteristic of GPS and GPSone, and the requirement of system operating cost, a hybrid position method is proposed, which employs both GPS and GPSone while takes GPS as the master technology for acquisition of position data.
