Hello louz 这种东西在国外已经玩的很开了,转一贴给你看看。 http://fellrnr.com/wiki/Running_With_A_Smartphone#Optimizing_GPS_Accuracy 注意几个: The GPS Accuracy of Smartphones is generally better than a dedicated running watch. (See below for details and caveats.) 得到一样就失去一样。。。 Different applications have radically different accuracy. While they are all using the same data, the sampling frequency and the smoothing they perform can make a huge difference. 不同的app用了不同数据处理方法,不知道你有没有用过不同app for runner,是不是记录出来的参数都不同呢?
