1278864 Gyroscopic apparatus TOKYO KEIKI SEIZOSHO K K 15 April 1970 [15 April 1969] 17969/70 Heading G1C A gyroscopic instrument for determining the meridian plane and the latitude at a location comprises a gyro platform 28 stabilized about three mutually perpendicular axis relative to inertial space, the platform 28 having a first axis maintained substantially horizontal at said location and being arranged to cause actuation of a device for generating a signal substantially corresponding to the time differentiation of inclination of the gyro platform about the first axis relative to a horizontal plane, a further device being provided for causing a gyro on the platform to precess in response to the signal from the generating device. As shown, the gyroscopic instrument which is mounted on a ship for indicating and determining latitude longitude, and pitch and roll angles of the ship comprises a pair of gyros 32, 33 and an accelerometer arrangement 51-53 mounted in a gimbal support on a ship, the gyros 32, 33 being supported on the platform 28 each in a gimbal mounting and arranged such that the spin axis of gyro 32 and the axis 43-43' of gyro 33 are parallel with the Earth's spin axis, such orientation being maintained by servomotors which are actuated by signals initiated by contactless detectors and the accelerometer arrangement, the signals being indicative of the values required. |
