Angular position sensors can be added to each axis. With higher resolution, faster sampling and better accuracy, rotation dynamics can be measured with precision. The sensors are frictionless (magnetic), very small and light to avoid adding inertia to the aircraft’s dynamics.
Also, the encoders can be replaced with smart motors to fully automate the gyroscope. This is useful to control the position, velocity, or torque of each axis, so calibrations of the autopilot can become an automatic process.
