METHOD AND DEVICE FOR CONTROL OF A SUNLIGHT ACQUISITION PHASE OF A SPACECRAFT

摘要

The present invention relates to a method (50) for control of a sunlight acquisition phase of a spacecraft (10) with a non-zero angular momentum of an axis DH, said spacecraft comprising a solar generator (12) able to rotate about an axis Y, comprising the steps: - (51) control of the spacecraft actuators so as to place said spacecraft in an intermediate orientation in which said axis Y is substantially orthogonal to the axis DH; - (52) control of the solar generator so as to orientate said solar generator towards the sun; - (53) control of the actuators of the spacecraft so as to reduce the angular momentum of said spacecraft; - (54) control of the actuators of the spacecraft engine so as to place, said spacecraft in an acquisition orientation in which the axis Y is substantially orthogonal to the direction Ds of the sun with respect to the spacecraft.
