<p>MAPPING APPARATUS EMPLOYING TWO INPUT AXIS GYROSCOPIC MEANS Mapping apparatus comprises:a) an angular rate sensor such as a gyroscope and a carrier frame therefor,b) the gyroscope characterized as having a spinning rotor and torsion structure defining a gimbal, and wherein the rotor spin frequency has a predetermined relation to a resonant frequency of said structure,c) the gyroscope further characterized as having multiple axes,d) drive means operatively connected with said frame to rotate the frame about one of said axes, ande) the gyroscope having means to detect rotor pivoting about another of such axes in response to said rotation of the frame. A second gyroscope may be employed, with its frame rotated by the same drive means; and corresponding axes of the two gyroscopes are typically orthogonally related.</p> |
