Such as enter basement , tunnel etc.
Thank you very much !
This article (in Czech) http://navigovat.mobilmania.cz/blesko...
describes a new way of significant improving of GPS position using gyroscope and accelerometer.
I don’t think it is something “new” because the idea is quite simple but I also don’t think many applications use it (maybe it is difficult to implement).
Generally gyroscope and accelerometer can tell you how the devise is moving and together with several previous GPS positions you can estimate (optimize) current GPS position quite well. Also this method can provide quite exact position even if GPS signal is lost for some time.
Can you implement it?
