text: The second property of gyroscopes with three degrees of freedom—precession under the influence of an applied force—forms the basis for the directional gyroscope (course indicator) and for important navigational instruments: the gyrocompass, which determines the geographic meridian, and the vertical gyroscope (azimuth gyroscope), which determines the true vertical direction (horizon).
