The navigation board is equipped with a number of sensors to ensure the stability of the AR.Drone 2.0.
Ultrasonic sensors to measure altitude changes, Altimeter sensor for improved accuracy of altitude corrections, 3-axis digital accelerometer to monitor positional movements, 2-axis gyroscope and a precision piezoelectric gyroscope for Pitch, Roll and YAW measurements, 3-axis magnetometer for orientation purposes
The sensors collect the overall feedback from the AR.Drone 2.0. The fusion of the data provides the Euler angles of the AR.Drone 2.0. The Euler angles are used for stabilization. The navigation board software may be updated when you update the AR.Drone 2.0 software.
This kit includes one navigation board and four screws.
