Description

一种定位增强的方法及设备 技术领域
本文涉及但不限于定位领域，具体地说，涉及一种定位增强的方法及设备。
背景技术
随着时代的不断发展，定位技术受到越来越多的重视，对定位精度也提出了更高的技术要求。
GPS定位技术由于信号损耗等原因，在室内信号变弱，使得定位终端无法搜索到足够的星；蜂窝网系统由于定位误差很大，无论在室外还是在室内都无法达到足够的精度，无法满足不断提高的定位精度需求。
为了解决高精度定位问题，通常方式是在地面建立无线定位系统，其各个定位信号站在近地布设，定位实现方式有多种，例如采用卫星制式的地面伪卫星系统、无线局域网系统等，其中，地面伪卫星系统需要手机能够处理地面卫星和太空卫星信号的共存，对其动态范围提出很大的要求；无线局域网主要采用基于信号强度的测距方法，定位精度严重依赖布设的网路密度。
可以看出，为了满足高精度定位需求，不同的定位系统采用了不同的定位方案，但定位方案的性能容易受到环境因素变化的影响，例如到达时间、到达时间差等通过时间计算传播距离的方法的定位精度容易受到多径信道传播的影响，基于信号强度、信号统计信息等指纹类定位算法的定位精度容易受到环境中物体移动、变化等影响，基于重力场、磁场等自然界特征类定位算法的定位精度容易受到地质变迁、宇宙变化等影响。
