  • Is the baro now reporting actual field elevation when coupled to the GPS?  I show 5000 feet at start up and the baro does not reset to 0 when I arm.  Yes I have foam covering the sensor with enough room for it to breath.  I am at 5000 Field elevation that's why I find it coincidental. 

    Or is my sensor bad?

  • Im having the same issue.   Im using the 2.5 APM in a Multirotor and the altitude is way off.  what is the best way to cover the the barometer to make it more accurate?

    The barometer is calibrated at startup using the GPS. If you are indoors the GPS accuracy is limited at best, even though you get a 3Dfix there is an error margin. I'm not sure when the barometer calibration is completed in arducopter as I couldn't find a link in the arducopter docs, just some in arduplane http://code.google.com/p/ardupilot-mega/wiki/StartingArduPilotMega
  • Nothing strange with what you write, read and learn more.

    Do you have sonar installed? Keep in mind the baro is very susepable to wind, do you have it covered? Did you fly and try ALT HOLD?
