摘要： This invention relates to a vibration-type gyro apparatus for measuring an angular velocity using the Coriolis force exerted on a tuning fork. The tuning fork has two vibrational members symmetric about a Z axis. The two vibrational members vibrate along Z axis and are displaced along a Y axis by the Coriolis force. Each of the two vibrational members includes a cantilevered tabular member arranged along an XZ plane and has a shape symmetric about the center axis thereof. Electrode sections are formed on the two sides of the vibrational members, and electrodes are formed in the internal space of a casing at positions corresponding to the electrode sections. The electrodes are arranged by being deviated outward or inward of the center axis of the vibration members with respect to the electrode sections. Each of the electrodes is supplied with a displacement detection AC voltage and a control voltage from a detection and drive circuit.

摘要： An antenna having a central axis is supported on a supporting member which in turn is supported on an azimuth gimbal. The antenna and the supporting member are rotatable around an elevation axis perpendicular to the central axis gimbal is supported on a base and is rotatable around an azimuth axis perpendicular to the elevation axis. A first gyro having an input axis parallel to the elevation axis is secured to the supporting member, and a second gyro having an input axis perpendicular to both the central axis and the elevation angle axis is secured to the supporting member. An accelerometer is provided for outputting a signal representative of an inclination angle of the central axis relative to a horizontal plane. An azimuth transmitter is provided for outputting a signal representative of a rotation angle of the azimuth gimbal around the azimuth axis. The difference between a signal corresponding to the altitude angle of the satellite and the signal of the accelerometer is fed to the torquer of the first gyro, while the output signal of the azimuth transmitter and the signals corresponding to the ship's heading azimuth and a satellite azimuth angle are fed to a torquer of the second gyro to thereby direct the central axis of the antenna to the satellite.
