Chapter 7 Gyroscopes

The gyroscope is a sensor intended for the measurement of the angular rotation of a mobile vehicle with respect to the inertial frame of the fixed stars.

The rotation is measured with respect to the inertial reference frame, not the laboratory or a generic relative frame, and this gives the gyroscope a special place among sensors. Since the early times of electronic aids to navigation, the gyroscope has been widely used in a range of applications, including inertial navigation, dead reckoning, attitude heading, horizon sensor, etc., which all require the inertial-sensing property.

Before the advent of the laser, mechanical gyroscopes (MG) were employed with success. An MG is based on the measurement of the Coriolis force ...
