PROBLEM TO BE SOLVED: To prevent the sensitivity of a mechanical rate gyroscope from including the influence of various uncertainties.;SOLUTION: The gyroscope has a mechanical sensor 102 which includes a first drive system 114 for generating a drive force Fd to cause a mass to vibrate relative to a base plate, a displacement sensor 116 for measuring a deflection caused by a Coriolis force generated in response to an angular speed, and transverse drive systems 166 and 168 for generating a feedback force Ff to cancel the Coriolis force, and a control circuit which provides the first drive system with an AC drive for generating the drive force Fd, and provides the transverse drive system with a feedback signal of a complete cycle of an AC drive for generating the feedback force Ff. The first drive system includes a segment of a first number Nd. The transverse drive system includes a segment of a second number Nf, and the segment has a form equal to the segment of the first drive system and is transversely oriented relative to the segment of the first drive system. Fd/Ff is configured to be proportional to Nd/Nf.;COPYRIGHT: (C)2011,JPO&INPIT
