| Number | Title | Issue Date |
| 4294420 | Attitude control systems for space vehicles An attitude control system is provided for a body-stabilized orbiting space vehicle having roll, pitch and yaw axes. Sensors carried by the vehicle provide signals representative of angular deviations about at least two of said orthogonal axes. An actuato... | 10/13/1981 |
| 4288051 | Method and apparatus for controlling a satellite A satellite, especially a geostationary satellite which may be stabilized in its three major axes and which has a spin wheel or momentum wheel supporting a position control system and which also has an engine or propelling system, is controlled by actuati... | 09/08/1981 |
| 4272045 | Nutation damping in a dual-spin spacecraft A dual-spin spacecraft having a momentum wheel spinning relative to a platform to provide bias momentum utilizes cross products of inertia (POI) existing in the platform between the spinning axis and the transverse axes to achieve nutation damping. When t... | 06/09/1981 |
| 4230294 | Closed loop roll control for momentum biased satellites An attitude control and stabilization system for momentum biased satellites utilizing a pair of counterrotating flywheels mounted parallel to its yaw axis. The speed of one of the wheels of the pair is controlled by sensing and correcting the roll axis er... | 10/28/1980 |
| 4174819 | Controller for the attitude stabilization of a satellite A controller for the attitude stabilization of a satellite. The controller odifies the action of a first control circuit by responding to the signals of attitude $c; and angular velocity of attitude $c; developed by the first control circuit. A secon... | 11/20/1979 |
| 4170904 | Single-axis disturbance compensation system The invention relates generally to an improved system for sensing and compensating for external disturbance forces acting on a satellite while in orbit. A proof mass member is housed within an enclosure and shielded from external, non-gravitational forces... | 10/16/1979 |
| 4161780 | Spin rate timing system Apparatus for use in determining the orientation of a spinning spacecraft d for controlling the attitude motion thereof. In response to commands from an external processor, the apparatus enables a selected thruster at a commanded time delay after a solar-... | 07/17/1979 |
| 4129775 | Glint capture system for improving lock stability of coat An imaging detector system for improving the lock-on stability of an optical system and in particular a multi-dither coat system. A quadrant non-coherent detector is disposed beneath a variable stop iris for receiving focused light from a target. The quad... | 12/12/1978 |
| 4117318 | Optical position pick-off in zero-drag satellite An optical position pick-off for proof-mass in a zero-drag satellite is obtained by placing a spherical mass shielded from all forces except gravity, between a flat screen having four equally spaced photodetectors and a light source. The mass interrupts t... | 09/26/1978 |
| 4071211 | Momentum biased active three-axis satellite attitude control system Control of an active three-axis multiple-wheel attitude control system is provided with a bias momentum to achieve stiffness about the pitch axis. With this stiffness, the system overcomes the inherent inability of a zero momentum system employing the sun... | 01/31/1978 |
| 4012018 | All sky pointing attitude control system In a strapped-down gyroscope space vehicle attitude control system, a method and apparatus are provided for gyro drift and input axis misalignment error compensation employing a sun and a star tracker and preselected vehicle calibration maneuvers. During ... | 03/15/1977 |
| 3996804 | Method for remotely determining the dynamic imbalance of and for changing the spin rate and center of gravity of a spinning body A method for remotely determining the dynamic imbalance of and for changing the spin rate and center of gravity of a spinning spacecraft which utilizes the communications channel between the spacecraft and the receiving terminal, the master index pulse ge... | 12/14/1976 |
| 3984072 | Attitude control system An attitude control system for a space vehicle in which angular rate signals are generated by rate gyros mounted closely adjacent to gimbaled engines at the rear of a vehicle, and wherein error signals representative of a commanded change in vehicle angle... | 10/05/1976 |
