[QUOTE="Dronason, post: 11686, member: 553"] Seems you are on the good way for a solution. You can try to do the famous IMU calibration but I don't know if it include any aspect related to the vertical sensor, not sure at all. The vertical distance sensor is based on an infrared laser beam.and for, ambiant light and reflection factor of the ground influence it. You can test it to see what the app says if you move it at some height, I don't think that the motor need to be turned on, but in worst case it has to be tested during a short real flight. Another way is to do a longer test flight and upload the Go4 app flight log here [URL='http://www.google.com/url?q=http%3A%2F%2Fwww.phantomhelp.com%2FLogViewer%2FUpload%2F&sa=D&sntz=1&usg=AFQjCNEgmpT1VEFdqPqAnh4qsqDEecGoBQ']DJI Flight Log Viewer[/URL] in that page you will see column for "IMU Altitude" (barometer) and [B]"[/B]Altitude VPS" (the optical sensor). This way you can check what is reporting the vertical sensor. Note that often it will report 0 as no data. Also the IMU altitude (barometer) can have changed when you land at same location if atmospheric pressure has changed or sensor drifted a little. [/QUOTE]
