| | Satellite Attitude Control Using CMG - ONERA / DCSD-ENWho are we ?Systems Control and Flight Dynamics... Satellite Attitude Control Using CMG. When tops are no longer toys.... Our work concerns only one-axis CMGs.... They have better efficiency than flywheels and are a powerful solution for satellite attitude control, but they are much more complex to use.. |

| 4. | - ONERA / DMPH |
| | The accelerometers provide not only the scientific data but also the data for the fine satellite attitude and orbit control system.... The attitude residual motion is also very finely controlled to limit the centrifugal and angular accelerations submitted asymmetrically by the two test masses when they are not perfectly centred.... |
