Barometric Altitude. #14

Closed ED6E0F17 closed 8 years ago

Atmospheric pressure is more accurate than GPS for calculating Ascent Rate at low altitudes. This should give a more stable/accurate landing prediction on the live tracker.

It would be interesting to compare GPS altitude at burst with the equivalent Ardupilot method:

Ardupilot's atmospheric model is inaccurate above 2km. Readily available pressure sensors are not useful at 30km or above. I have no intention of using barometric data to calculate the altitude.

I hope you don't want to break an altitude record :p
