车联网基站定位纠偏算法研究

Research on rectification algorithm of base location in Internet of Vehicle

当前车联网终端普遍采用GPS/LBS双模定位,定位精度依赖于终端上报的基础数据。当终端在隧道、车库或者周边基站稀疏情况下,LBS定位会出现较大误差。本文针对上述问题,提出了一种基站定位的纠偏算法。该算法依据终端上报的历史数据对当前上报位置做偏差认定及趋势分析,从一定程度上减小了定位偏差,提高了定位精度。

The current IoV terminal commonly used GPS/LBS dual-mode positioning.Positioning accuracy depends on the base data reported by the terminal.When the terminal in the tunnel,garage or peripheral base station sparse situation,LBS positioning will appear larger error.This paper propose a rectifi cation algorithm of location based service.The algorithm is based on the historical data reported by the terminal to identify the location of the current deviation and trend analysis.To some extent,the positioning error is reduced and accuracy is improved.
