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。
GPSone positioning technology, is the world’s most advanced positioning technology. It embeds wireless network assisted GPS positioning and CDMA triangulation positioning into the CDMA terminal chip, and combines these two technologies organically to form GPSone hybrid positioning technology that is unique in the mobile positioning market. Abandoned the traditional location of the terminal adopt GSM + GPS or CDMA + GPS mode. With less blind, wide adaptation, low cost. Overcome GPS in indoor, underground parking, tunnels, high-rise urban buildings and other environments, can not locate or locate the shortcomings, improve the positioning accuracy and positioning success rate. The article first studies the existing multiple positioning technologies, analyzes the advantages and disadvantages of various positioning technologies, analyzes and studies the GPS global positioning system and the gpsOne positioning technology based on the CDMA wireless cellular network. According to the advantages of these two positioning technologies Shortcomings and system operation costs, a GPS positioning technology and gpsOne positioning technology for hybrid positioning, GPS-based positioning data acquisition program.
