Figure 27: FLIGHT MODES CHANNEL SETTINGS
(v) SENSORS
This screen displays the status of the Accelerometer (IMU) and Compass sensors. 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.
ACCELEROMETER CALIBRATION
PRISM’s accelerometers are calibrated from the factory and should not require an
additional calibration before flight. It is important to note however that operations in
extreme temperatures may require an additional accelerometer calibration. In order to
calibrate the accelerometer, simply enter into Sensors -> Accelerometer, then follow the
instructions. After placing the vehicle in each position, hold the aircraft still and press
“Next”, until complete. Once this is finished, a vehicle reboot must be completed in
order to fly.
