Abstract
In order to shift the moment of inertia H.sub.i of a body in rotation initially in rotation approximately about its principal axis of inertia Z into any given orientation H.sub.F one applies transversely to the axis Z three torque impulses in a plane containing H.sub.i and H.sub.F, the first for a time T.sub.1, such that, at the end of one rotation of a satellite about itself, the axis Z shifts to Z.sub.1 in the plane bisecting H.sub.i and H.sub.F, whilst the kinetic moment moves to H.sub.1, the second impulse at the instant when the principal axis of inertia is at Z.sub.1 for a time T.sub.2 appropriate to shift the kinetic moment into a position H.sub.2 symmetrical with H.sub.1 with respect to this bisecting plane, and the third impulse at the instant when the principal axis of inertia is parallel to H.sub.F for a duration equal to T.sub.1.
