  • Attitude determination system and method with outer-loop gyro scale-factor non-linearity calibration
    Patent number: 6615117
    Abstract: A method and apparatus for calibrating rate sensor measurements to compensate for rate sensor scale factor non-linearities. An outer loop compensator compares current rate sensor scale factor estimates with the current scale factor non-linearity compensation, and deviations from the current non-linearity compensation are corrected in an updated compensation.
    Type: Grant

  • Method and apparatus for controlling spacecraft attitude with rotational star trackers
    Patent number: 6236939
    Abstract: High precision spacecraft attitude determination is produced by specially positioning the spacecraft's star trackers and then filtering out measurement errors produced from star tracker electronics. In addition to the conventional azimuth and elevation controls used for star tracker pointing, the star tracker detector array is rotationally positioned about its boresight so that its pixels are traversed by the imaged star path at an angle within 20° of diagonal. This forces both vertical and horizontal spatial error components in the detector plane to a high frequency range at which they can easily be filtered out in common.

  • Dual spin zero momentum satellite system
    Patent number: 6152402
    Abstract: An attitude control system for a spacecraft which includes a bearing power and transfer assembly. The bearing power and transfer assembly is disposed between a first body and a second body. The first body and the second body are counter-rotated with respect to each other by the bearing and power transfer assembly such that the overall spacecraft momentum about the spin axis of the bearing and power transfer assembly is nominally zero.
