Sensor Calibration

The status of the Accelerometer (IMU), Gyroscope and Compass sensors can be viewed in Watts AMC shown in the image below. A green dot indicates healthy sensors. Users will perform required IMU and compass calibrations from this screen. IMU calibrations are accomplished by positioning the aircraft in various attitudes while the sensors take readings. Compass calibrations require the user to rotate the aircraft randomly along the major axes until the progress bar fills up, which may take about two minutes.
