A rate gyro is a type of gyroscope which, rather than indicating direction, indicates the rate of change of angle with time. The gyro has only one gimbal ring, with consequently only two planes of freedom and is used to measure the rate of angular movement.

This Rate Gyro was supplied for the Harrier SAAHS, (Stability Augmentation and Attitude Hold System). It was manufactured by Elliotts using a Northrop GR-H4 Gyro.
