rate gyro

rate gyro
A gyro having one plane of freedom at right angles to the plane of rotation and constructed so that a calibrated spring opposes the precessive forces to indicate the rate of rotation about the plane at right angles to both the plane of rotation and the plane of freedom. A turn and slip indicator uses a rate gyro. See also rate of turn.

For the system, working in the precision stabilization mode, it is necessary to take into consideration that every contour channel includes the platform with payload, motor, pulse-width-modulator (PWM), and rate gyro [12, 15].
Each rate gyro channel is mated with a military qualified and proven ASIC.
An attitude-based autopilot receives its roll and pitch reference signal from the attitude gyro, while a rate-based autopilot listens to a rate gyro inside a turn coordinater.
The Satellite Navigation system comprises 3-Axis rate Gyros, Magnetometers, Accelerometers, Digital sun Sensor and Star tracking Sensors in order to provide accurate attitude and orbital determination.
S-TEC claims their rate gyros have a mean time before failure of over 8000 hours because the rotor spins at one third the speed of the average attitude gyro.
Weighing around 3.5 ounces, the "Micro INS uses highly reliable micro electromechanical systems sensors, including accelerometers, rate gyros, magnetometer and air data pressure sensors, along with a differential ready, Wide Area Augmentation System-enabled GPS receiver," Rockwell Collins said.Rockwell Collins will deliver its Micro Inertial Navigation Sensor (INS) for the FT-200FH.
Although the outputs of rate gyros can be integrated to generate high bandwidth attitude estimation, the long-term accuracy is poor due to integration errors.
