Attitude control system

Centre National d'Etudes Spatiales CNES - 10/19/2016


The invention deals with a 3 wheel con guration for a satellite attitude control. This innovative system, in particular having wheels in an o -axis con guration of the satellite, allows to control the 3 wheels simultaneously with a non-zero speed for a non inertial pointing.


Gain in terms of weight and size Costs - Allows the use of less accurate and less expen- sive wheels


Innovative and e cient technology - Stable pointing - Absence of discontinuity, the wheels can be maintained around high speeds - Compact - Gain of actuation given by the o -axis con guration of the wheels
