METHOD AND SYSTEM TO RULE OUT SATURATION OF SPACECRAFT INERTIAL WHEELS Russian patent published in 2015 - IPC B64G1/28 B64G1/22 

FIELD: transport.

SUBSTANCE: set of inventions relates to control over spacecraft orientation with the help of gyro flywheel actuators, particularly, to their unloading at saturation. Said actuators saturated, decision (10) is made on initiation of unloading manoeuvre. Permission (20) of manoeuvre initiation is issued when spacecraft orbital position stays in allowable area of manoeuvre. Manoeuvre proper (30) is executed by spacecraft turn through somewhat angle (in particular, through 180 degrees) around the fixed guidance axis (Z). Said turn can be performed with the help of one of said actuators. Said manoeuvre makes external disturbing moments acting at spacecraft vary their direction, hence, become unloading. Abode described procedure is reiterated.

EFFECT: jet fuel savings, simplified control system.
