METHOD OF CONTROLLING SPACECRAFT CENTER OF INERTIA IN DOCKING Russian patent published in 2013 - IPC B64G1/24 B64G1/64 

FIELD: transport.

SUBSTANCE: invention relates to space engineering. For control over spacecraft center of inertia in docking displacement angle relative to boresight with lag and angular velocity of boresight with lag are measured. In case displacement angle exceeds preset operation threshold or angular velocity exceeds preset operation threshold or displacement angle is smaller than preset operation threshold control action is applied to center of inertia. Duration of control action varies with modulus of displacement angle and modulus of boresight angular velocity with due allowance for distance while the sign is opposite the displacement angle and that of boresight angular velocity. Mean velocity is defined by drift angle. Drift angle is defined by boresight angular velocity at time interval as the sum of lags in determination of displacement angle and boresight angular velocity. With mean velocity equal to or exceeding half the operation threshold in boresight angular velocity, control action is applied to center of inertia. Duration of control action varies with modulus of mean velocity with due allowance for distance while sign is opposite that of mean angular velocity. Accumulated drift angle and time interval are zeroed to start defining the drift angle and mean velocity.

EFFECT: higher accuracy of boresight angular velocity adjustment.
