Abstract
A closed-loop magnetic roll/yaw control system for high inclination satellites where the predominant component of the geomagnetic field lies in the orbit plane of the satellite. The system includes a torquing means that forms a magnetic dipole moment parallel to the pitch axis. The torquing means is energized to minimize roll or yaw error only in two spaced portions 1 and 3 of its orbit. Each of the portions lie between the extension of the earth's magnetic equatorial plane and a second plane normal to the orbit and passing through the magnetic poles of the earth. Portions 1 and 3 are those parts of the orbit in which the satellite is traveling toward the second plane. The torquing means is de-energized after the satellite crosses the second plane and is in either of the remaining spaced portions 2 and 4 of its orbit.
