LBS定位漂移----续

自己做的模块,使用的是AIR202的模块,外挂MCU。

MCU通过AT指令(AT+AMGSMLOC)控制AIR202模块,获取经纬度信息,然后发送到服务器。

测试过程中,发现位置漂移的厉害!并且目标位置固定。如下图:

后台下载的轨迹数据:

下面的是今晚使用笔记本电脑,通过串口调试助手,接的S5开发板去该路段测试的数据:

求大神帮忙分析下原因!

因定位模块是用于公司现有产品的,进行产品的定位,防止串货的。

如此大的漂移,已经跨省了,肯定会超出经销商的销售范围,因此比较担忧!

合宙基站数据库数据错误,可能是伪基站干扰,,只能发现一个解决一个,给合宙提报IMEI和时间点,可以查到当时用于定位的基站编号,合宙再去更新该基站的位置。

基站lac 转换成坐标,我用的高德 smart hardware API, 免费的。很准的。
