Abstract
A method of controlling the attitude of a spacecraft in spinning around itself with a non-zero total angular momentum H. The spacecraft includes a set of inertia flywheels configured to form an internal angular momentum H. The axis of the total angular momentum His aligned with a principal axis of inertia of the spacecraft, in the course of which the inertia flywheels are controlled to form an internal angular momentum H. The following expression, in which J is the inertia matrix of the spacecraft:()is negative if the principal axis of inertia targeted is the axis of maximum inertia of the spacecraft and is positive if the principal axis inertia targeted is the axis of minimum inertia of the spacecraft.
