The present invention improves the orbital maneuvering and power generation capabilities
of a system of a satellite(s) connected with a conducting tether(s) by spinning
the system about its mass center at an angular rate which is relatively high compared
to the average orbital rate. An improvement in tether performance is achieved because
at many times during rotation the tether is positioned at much better angles with
the magnetic field and significantly higher currents are driven through the tether
without destabilizing the system. The current can flow either in the direction
of the EMF induced in the tether, or in the reverse direction, depending on the
tether orientation with respect to the magnetic field and the mission goals. The
reverse current is driven by the onboard power sources. Spinning electrodynamic
tether systems can also be lighter and simpler in design and more flexible in operation.
