Most of mechanical sensors and actuators located on the satellite main body induce many disturbances and influence stringent pointing and stability requirements. Momentum and reaction wheels are essential instruments for the satellite attitude control systems, but they are also one of the large disturbance sources. The authors developed a device to detect wheel disturbances precisely. In the test, a ball bearing type reaction wheel is mounted on an air- floating block of this device and the displacement caused by wheel disturbances is measured. The wheel disturbances measured by laser range sensor and force/torque sensor are evaluated and the usefulness of low frequency and level disturbances detection is shown.
