Question

Why is a tuning fork gyro better than the vibrating cylinder type gyro?

(a) Reduce base motion

(b) Low power consumption

(c) Easy to manufacture

(d) Low run up time

This question was posed to me in quiz.

I need to ask this question from Gyroscopes topic in section Satellite Radio Navigation  & Inertial Navigation of Avionics

Answer 1

Right answer is (a) Reduce base motion

Best explanation: The vibrating mass rate gyro is a simple instrument suffers from the unacceptable characteristic that the smallest linear motions applied to its base cause unacceptably large errors. To overcome the effect of base motion, it is necessary to use balanced oscillations in which the oscillations of one mass are counter-balanced by equal and opposite motion of a second equal mass as in the case of tuning fork gyro.
