Question

Which of the following is false with respect to MEMS gyro?

(a) Low failure rate

(b) Low cost

(c) High maintenance

(d) Less power consumption

This question was addressed to me by my college director while I was bunking the class.

Query is from Gyroscopes in chapter Satellite Radio Navigation  & Inertial Navigation of Avionics

Answer 1

Correct choice is (c) High maintenance

Easiest explanation: Micro machined vibrating mass rate gyros exploit semiconductor manufacturing technology for mass production. They are extremely reliable and rugged devices with low power consumption and offer the major advantage of relatively low cost. They also do not require the very high maintenance that spinning rotor gyros require.
