摘要： A gyro apparatus includes a support in a base table for supporting one end of a vibrating member which has a circular cross-section and which is driven by a drive apparatus mounted on the base table to vibrate it in the longitudinal or axial direction. The vibrating member may be light conducting and a light source sends light through it which is projected onto a light detector so as to detect vibrations perpendicular to the axis direction of the vibrating member.

摘要： A fiber optic gyro can overcome the defects encountered with conventional fiber optic gyros of phase-modulation method, closed-loop system with serrodyne modulation and digital modulation. A reference phase difference .DELTA..beta. and a ramp phase difference .sigma. are generated in an interference light intensity signal I by use of a triangular waveform, i.e., delta serrodyne waveform signal. The reference phase difference .DELTA..beta. is changed to constant values .DELTA..beta..sub.A and .DELTA..beta..sub.B whose absolute values are the same and whose signs are different at every times T.sub.A and T.sub.B. A phase x of the interference light intensity signal I becomes equal to x=.DELTA..theta.+.sigma.+.DELTA..beta.. The ramp phase difference .sigma. is controlled so as to satisfy .DELTA..theta.+.sigma.=0. Accordingly, at the stable point of the control loop, a Sagnac phase difference .DELTA..theta. is equal to the ramp phase difference .sigma.. Further, a phase x of the interference light intensity signal I does not contain the Sagnac phase difference .DELTA..theta., and hence x=.DELTA..beta.. Also, a fiber optic gyro can eliminate a bias, in particular, optically-generated bias. In a fiber optic gyro of phase-modulation method or delta serrodyne system, a phase controller is supplied with a phase control voltage signal V.sub.S of period T and a square wave signal V.sub.2 of period T for correcting an optical bias caused by an amplitude modulation generated by the phase control voltage signal V.sub.S in the added form. The square wave signal V.sub.2 has a constant magnitude H and is inverted in polarity at points in which the phase control voltage signal V.sub.S is maximized or minimized. The magnitude H and the polarity of the square wave signal V.sub.2 are selected such that an optical bias is minimized.

摘要翻译： 光纤陀螺可以克服常规光纤陀螺相位调制方法，带有锯齿波调制和数字调制的闭环系统所遇到的缺陷。 在干涉光强度信号I中通过使用三角波形即三角波形波形信号产生参考相位差DELTAβ和斜坡相位差σ。 参考相位差DELTA beta被改变为恒定值DELTA beta A和DELTA beta B，其绝对值相同，每个符号TA和TB的符号不同。 干涉光强度信号I的相位x变为等于x =DELTAθ+ sigma +ΔTATA。 控制斜坡相位差σ以满足DELTAθ+ sigma = 0。 因此，在控制回路的稳定点，Sagnac相位差ΔTATA等于斜坡相位差σ。 此外，干涉光强度信号I的相位x不包含Sagnac相位差DELTAθ，因此x =ΔTATA。 此外，光纤陀螺仪可以消除偏压，特别是光学产生的偏压。 在相位调制方法或三角速度系统的光纤陀螺仪中，相位控制器被提供有周期T的相位控制电压信号VS和周期T的方波信号V2，用于校正由产生的幅度调制引起的光偏置 通过相位控制电压信号VS以相加的形式。 方波信号V2具有恒定的幅度H，并且在相位控制电压信号VS最大化或最小化的点处极性反转。 选择幅度H和方波信号V2的极性使得光偏置最小化。

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.

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.
