Navigation Computer - PIEZO Gyro Sensor
The piezo gyro sensor measures the motion of the vehicle around its vertical axis using the Coriolis force. The Coriolis force is a force which accelerates a foreign body moving away from the rotational axis against the direction of rotation of that axis. In operation, a mass inside the sensor is excited to a point where it begins to vibrate, similar to the principle of a tuning fork. The vibrations travel perpendicular to the rotational axis and cause continuous potential charge of the mass in relation to the rotational axis. The forces can be measured easily and are converted into a yaw rate to calculate direction.
