초록

Spacecraft momentum management techniques are coordinated with station-keeping maneuvers or other delta-V maneuvers. A body stabilized spacecraft attitude is controlled, the spacecraft including at least one momentum/reaction wheel, and a set of thrusters. A first momentum storage deadband limit is adjusted, the adjustment being related to a first delta-V maneuver window. A momentum management strategy is executed with the adjusted first momentum storage deadband limit such that a first thruster firing that performs desaturation of the momentum/reaction ...

1. A method comprising: controlling an attitude of a body stabilized spacecraft, the spacecraft comprising at least one momentum/reaction wheel configured to maintain the attitude with respect to a spacecraft axis by storing momentum, and a set of thrusters, the controlling including: executing a momentum management strategy coordinated with a first delta-V maneuver, the first delta-V maneuver to be conducted by firing a first thruster during a first window for conducting the first delta-V maneuver, the momentum management strategy including: shifting a ...
