In the case of three-axis stabilization, also known as body stabilization, the stabilization is achieved by controlling the movement of the satellite along the three axes, i. e. yaw, pitch and roll, with respect to a reference... The system uses reaction wheels or momentum wheels to correct orbit perturbations.  2, record 1, English, - three%2Daxis%20stabilization

The gyros are used to maintain the platform's inertial orientation by sensing rotations of the platform caused by vehicle-rotation-induced friction at the gimbal pivot points... One gyro-called the vertical gyro-is oriented so its input axes are aligned with the X and Y platform axes; its input axes provide IMU [Inertial Measurement Unit] platform roll and pitch stabilization. The second gyro is oriented so that one input axis lies along the platform's Z axis and the other lies in the X-Y plane. This gyro-the azimuth gyro-provides platform yaw stabilization with the Z input axis, while the second input axis is used as a platform rate detector for built-in test equipment.  3, record 2, English, - azimuth%20gyroscope

The sensors for angular velocity are vibrating gyroscopes (3 axes, to detect rotation and pitch/roll pendulations of the payload). An error signal is obtained differencing the signal from the azimuth gyroscope and a constant level settable from the telemetry, which controls the speed of rotation. Such error signal drives an analog PID [Proportional Integral Differential] circuit; the output of the PID is connected to the PWM [Pulse Width Modulation] driver supplying current to the pivot azimuth motors.  3, record 2, English, - azimuth%20gyroscope

The gyroscopic frame is responsible for the stabilization of the platform. Three rate gyroscopes are fitted in the frame with their input axes mutually perpendicular... Pitch, roll, and yaw are detected by the three gyroscope input axes. The gimbal deflection of each of the gyroscopes is converted into a signal voltage that, when amplified, drives a servomotor which, via a gear train, rotates the frame back to its original position.  2, record 6, English, - gimbal%20deflection

Roll-rate gyro. The roll-rate gyro is less sensitive than the P [pitch] and Y [yaw] rate gyros. Roll-rate control limits fast roll rates during boost, before roll stabilization takes place.
