• Altitude sensor filtering improvements. Moving Average used for filtering. Depth of the filtering is 60 points (about 1.5 seconds span)
• Linear regression used for VSI calculations. VSI stability improved significantly. Regression calculated over 15 point spaced about 200ms apart. Altitude points are taken from filtered altitude data (Moving Average).
• Single dimension Kalman filter has been fully removed from the code.
