Abstract
A system for autonomously unloading accumulated angular momentum on space craft reaction wheels in the attitude control systems with external torques generated by the interaction of spacecraft magnetic dipoles with the earth's magnetic field. An onboard computer receives reaction wheel speed information, wheel speed threshold and geomagnetic latitude information and controls magnetic dipoles that will create a spacecraft torque and desaturate reaction wheels in a closed loop system.
