Abstract : An analysis was made of the problems associated with geomagnetic torquing, especially that no torque could be generated about an axis parallel to the earth's magnetic field. Disturbing torques on a 20,000 pound space station were analyzed and estimated to be one-tenth foot-pound. Analog and digital computer simulations were made of the geomagnetic torquing and control moment gyro systems. The maximum magnetic moment required for each of three axes was 2.4 foot-pounds per gauss. The maximum required momentum storage capability was 1600 foot-pound-seconds. The total weight of both systems was 4000 pounds. (Author)
