Abstract
1279098 Controlling satellites HAWKER SIDDELEY DYNAMICS Ltd 1 Oct 1969 [1 Oct 1968 10 Dec 1968] 46608/68 and 58759/68 Heading B7W An attitude control system for a spin stabilized orbiting spacecraft or satellite 11 comprises one or more coils or electromagnets 13, the excitation of which is controllably variable, mounted with their magnetic axes 14 perpendicular to the spacecraft spin axis 12. Application of an excitation current which is pulsed cyclically (15, Fig. 1b, not shown), or which has an alternating waveform (16), of which one or more complete cycles occur for each revolution of the structure 11 and the magnet 13, causes the magnetic moment of magnet 13 to react with the component of the local magnetic field 17 which is parallel to the axis 12 to produce an attitude control torque 18 which controls the precession of the spin axis. The amplitude of any associated nutation which would remain after removal of the torque 18 may be made zero merely by suitable adjustment of the operation time of the torque and of the appropriate moment for removing it. If the stabilization angular momentum is generated by a flywheel 20 (Fig. 2, not shown) within the stationary spacecraft structure (19), the controlling torque is obtained from two electromagnets (22) on the structure (19) which have their magnetic axes perpendicular to the spin axis (21) and to each other.
