Spacecraft gyro calibration system

摘要

A method of calibrating a gyro ( 42 ) of a spacecraft ( 14 ) may include determining a yaw attitude residual of the spacecraft. Roll gyro bias residual is determined in response to the yaw attitude residual. The gyro ( 42 ) is calibrated in response to the roll gyro bias residual. A method of calibrating a gyro ( 42 ) of a spacecraft ( 14 ) may alternatively include disabling gyro calibration, gain scheduling, or resetting attitude and gyro bias covariance, for selective axes, for a yaw transient period. The gyro ( 42 ) is calibrated in a nominal fashion after completion of the yaw transient period.
