I've been recording tracks with GeoTracker on my Android. In places I have points that have altitudes higher than the peaks of a mountain. Like one altitude difference is 46 m.
How is it possible to get that big difference?
Is GPS on my Andorid that bad when it comes to accuracy or is it app itself, and why is this happening?
My device is:Sony xperia m4 aqua, I had High accuracy mode turn on. Specification for my phone: imei.info/phonedatabase/16958-sony-xperia-m4-aqua-e2303 (GPS: A-GPS/Glonass, GLONASS: No). I am also interested, based on this, how will I be able to figure out what is the accuracy of my measured position and altitude?
