一种GPS漂移数据过滤方法、系统及终端
摘要：
本发明公开了一种GPS漂移数据过滤方法、系统及终端，包括：获取GPS定位数据，搜索WIFI热点并保存；根据获取的WIFI热点变化修正定位数据。利用WIFI热点修正GPS数据，当使用者携带GPS过滤终端在有WIFI信号的环境中移动时，可以过滤短距离GPS漂移数据，使定位数据更准确。
摘要（英）：

The invention discloses a GPS drift data filtering method and system, and a terminal. The method comprises: acquiring GPS positioning data, searching for a WIFI hotspot and storing the hotspot; and correcting positioning data according to the change of the acquired WIFI hotspot. Because the GPS data are corrected by using the WIFI hotspot, when a user carries a GPS filter terminal and moves in anenvironment with a WIFI signal, short-distance GPS drift data can be filtered, so that the accuracy of positioning data is improved.
