A tethered satellite system is expected to have a wide variety of engineering applications, in addition to being used in atmospheric scientific observations. One of the key technologies for achieving such a system is the methodology for controlling the relative position of a subsatellite which swings back and forth, in or out of orbital plane, under tether tension control from the mother satellite. The Institute of Space and Astronautical Science (ISAS) of the Ministry of Education has formulated a conceptual plan of space tethered equipment (STEX) for which Nissan was entrusted with the system feasibility study. The authors have successfully derived the swing control laws through analysis in which an optimum control theory was applied to confirm the effectiveness of the laws by mathematical simulation.
