Abstract
A method for controlling an attitude control system () for a space vehicle (), the attitude of the space vehicle being controlled during at least one preparation phase followed by an observation phase during which an image capture is performed. In an attitude control system that includes a maneuvering subsystem () which includes at least one reaction wheel, the method includes, during the at least one preparation phase, a preparation step (), during which commands are issued to the maneuvering subsystem in order to control the attitude of the space vehicle, followed by a step () of stopping the at least one reaction wheel prior to the observation phase. In addition, during the observation phase, a fine control subsystem () having a lower vibration signature than that of the maneuvering subsystem, is sent commands in order to control the space vehicle's attitude. An attitude control system for a space vehicle is also described.
