gpsOne应用于车载导航的可行性分析

gpsOne是基于无线通信网络的GPS与基站定位相结合的组合定位技术，充分发挥了GPS和基站定位的优势，具有可工作区域广、定位精度高、成本低、实时性好和冷启动时间短等诸多优点，相比较于GPS定位，gpsOne更适合用于车载定位导航。但是，gpsOne单系统应用于车载定位导航仍然存在诸如工作盲区定位精度差和可靠性不足等缺点。因此，gpsOne应该与其它定位方式进行组合，实现优势互补，以进一步提高定位模块的工作可靠性和冗余容错能力。

The feasibility of a gpsOne vehicle navigation solution

GpsOne,which fuses GPS and wireless base station position signals,is a hybrid wireless assisted GPS technology.It provides position service through wireless communication networks.Compared with GPS,gpsOne is more suitable for vehicle navigation because of its advantages as wider workable zones(both urban,rural and even underground areas),higher position accuracy,lower price,and shorter cold startup time.However,gpsOne can't be used for vehicle navigation due to its large position error(more than 100m) when GPS signals cannot be received completely.Therefore,gpsOne should be assisted with other position modules to promote the reliability,redundancy and fault-tolerance of vehicle position system.
