Design and characteristics of device for sensing solar radiation and providing spacecraft attitude control to maintain direction with respect to incident radiation
Attitude control system for spacecraft based on conversion of incident solar radiation on movable control surfaces into mechanical torques
Antibacklash circuit for hydraulic drive system
Hydraulic drive system uses a second drive motor operating at reduced torque. This exerts a relative braking action which eliminates the normal gear train backlash that is intolerable when driving certain heavy loads.
Spacecraft attitude control system using solar and earth sensors, gyroscopes, and jet actuators
Photosensitive light source device for detecting unmanned spacecraft deviation from reference attitude
Spacecraft attitude control system optimization by parametric analysis of the magnitudes and directions of solar pressure torques
Attitude control of interplanetary spacecraft by solar radiation pressure
