报告摘要:

人们80%时间在室内,公共安全、应急救援、老幼关爱、物联网、军事国防等对室内“米级”精确位置服务需求爆发式增长。室内外无缝导航已成为国家导航产业中长期发展规划重要内容。卫星因建筑遮挡在室内及建筑周边无信号,故无定位能力;专建地面室内定位系统成本高;WIFI和蓝牙等局域定位系统布设密度大,一个大城市需数百万个设备,运维难。传统移动通信与广播网室内外定位成本低、覆盖广。但复杂建筑结构对无线信号传输形成了多重干扰,非直线传播与多径现象严重,基站到终端距离测量误差大,全球2G/3G/4G网室内定位精度普遍在“百米”量级。通过多年潜心研究,攻克了通信网室内“米级”三维定位国际难题,提出了共频带通信网增强定位理论方法与架构,实现了广域定位室内外精度1~3米,垂直1米,比国外公开精度高5-10倍。创新的移动通信、广播、无线网和卫星导航等多资源融合高精度定位技术,为我国导航服务探索了一条投入少、见效快的建设之路。成功研发了室内导航服务系统及产品,推进了我国室内导航产业化与位置服务发展,取得重大经济和社会效益

 

There are 80% human-living time for indoor activities, such as public safety, emergency rescue, children nursing, IOT (Internet of Things) and national defense, which have a great demand on high-accuracy LBS (Location Based Services). Navigations seamless around indoor and outdoor, have been a national long-term development plan for navigations in China. However, satellites can’t provide with indoor positioning and navigations, because there is no signals coverage around or inside buildings. It takes great cost to build a specialized system only for indoor positioning and navigations. Wi-Fi and Bluetooth can achieve a relatively high accuracy, but limited coverages would be hard to wide-area applications and managements. Traditional mobile communications and broadcasting networks have a great advance for wide coverages and low cost, but complex buildings structures bring signals with multiple interferences, non-rectilinear propagations and serious multipath effects. Therefore, the accuracy for indoor positioning by using 2G / 3G / 4G networks are still more than 100 meters, which seriously degrade high-accuracy LBS developments. This report analyses and reviews the present researches worldwide, and technologies challenges for high-accuracy LBS. Moreover, we focus on series of key technologies for positioning seamless around indoor and outdoor with sub-meter accuracy, which are based on mobile communications networks. The theories and frameworks with navigations enhanced in common communications bands are proposed. We also introduce the great progresses of LBS big-data services and industrial applications in China “XiHe” plan. At last, fusing mobile communications networks, broadcasting networks, wireless networks and satellite networks, have achieved high accuracy and wide coverage. The involutions provide with a low cost, quick construction scheme for China LBS.
