"Hello Diego,
I've also seen this issue. I'm 100% sure that the temperature raise due to electronics heat affect the barometer. So, I wait 10 minutes to stabilize the board temperature and press the reset button, to reinitialize the…"

test 2 - pressure [hPa]
test 2 - current_loc.alt [m]

"Make sure you're using the MAVLink 1.0 version of the MP. It's in the same directory. "
Diego replied to Diego's discussion Barometer question - Current location altitude error"ok. I'll try upgrading to version 2.50. I'm using version 2.32 because I'm having problems with the mission planner program and the mavlink version."
"...and please Diego do the same analysis again. Agree with Randy. Nice detailed analysis. thank you. "

"ArduPlane 2.32 is very old and there have been many changes, including to the baro library, since then. Please upgrade to 2.50 and see if the issue goes away. "

I'm using the ArduPlane code version 2.32.When I tried to do automatic landings I saw that the autopilot had problems with getting the correct altitude to turn off the motor or was coming to hight or to low. After checking the logs I concluded that the problem was the initialization of the home altitude.In each log I saw the same pattern:During the first 15-20 executions of the main…See More
