Autocalibration

I use autocalibration when measuring elevation during my walk and it seems that difference between Gps elevation and Elevation doesn't go to 0 meters and are not stable. Sometimes they increase to 50 meters sometimes they dicrease but never go to 0

I think the constant of time in the integrator is too long (more than 20 minutes) 10 minutes will be a good choice.

I doubt that it will ever converge and stay that way. The GPS vertical position error is quite a bit larger than the horizontal position error. Maybe more to the point, changes in barometric pressure due to weather are going to mess things up over time.

You are right, but the algorithm will converge with gps value once.
