I’m building a Wear OS variometer app for paragliding.
I’m fusing barometer and accelerometer data using a kalman filter to estimate (z, vz, az).
I noticed that SensorManager.getAltitude has almost 1m bias depending on the orientation of the watch.
Fixing this bias would greatly improve the accuracy.
