Title: Android logging inaccuracy
Post by: andyoxon on 11 April, 2015, 09:41:48 am

I use my phone for logging shorter rides - but any ideas what causes periodic gps logging like this on Android...  Tend to use MyTracks for bike on recommended defaults.

More often the track is bang on the road...

Poor sky view on day with bad track, as in less satellites over the horizon for the phone to track, track appears a bit coarser too ?

I've had mapping errors before that had everything offset by a uniform amount but this isn't that.
