APM2 altitude & barometer question


I've noticed the altitude reading under the "Quick" tab in mission planner seems to vary by a large degree just sitting on the couch next to me (3 - 4 meters). However when I go into the terminal and read the altitude through "test"->"altitude" my barometer readings are relatively steady and the altitude seems to vary only by 1m or so.

How come the readings are so different?

  • ok so i just watched Randy's video on you tube, https://www.youtube.com/watch?v=i0rEoBaJxiI and tried to check my readings using the tuning button but I get flat values for the barometer and accelerometers even if i'm moving the apm around.

    am i missing something?
