DEFINITION

Classification: 73/504.02

Angular rate using gyroscopic or Coriolis effect:

(under subclass 488) Subject matter wherein the determination of the time rate of change in position of the body is made by (1) rotating or (2) linearly moving an inertial element with respect to the body and measuring reaction forces on the element produced by rotation of the body about an axis of

rotation.
