Propulsion system for controlling the orbit and controlling the attitude of a satellite

A propulsion system for controlling the orbit of a satellite in earth orbit that has a kinetic moment accumulation capacity, and for the generation of torques helping to control the kinetic moment, said satellite being driven by a displacement velocity tangential to the earth orbit, the propulsion system comprising:

• a thruster for delivering a force along an axis F, and a motor-driven mechanism linked at a first end to the thruster and at a second end to a structure of the satellite,
• said motor-driven mechanism configured to displace the thruster on either side of the plane of the orbit and configured to orient the thruster so as to make it possible to control a component of the force perpendicular to the orbit in two opposite directions, to control the inclination of the satellite,
• said motor-driven mechanism configured to displace the thruster along an axis V parallel to the velocity of the satellite, and configured to orient the thruster so as to make it possible to control:
• a component of the force on the axis V, to control orbit,
• an amplitude and a direction of torque in a plane perpendicular to the axis F, to control the kinetic moment;
• wherein the propulsion system can control six orbital parameters of the satellite, and the motor-driven mechanism includes:
• (i) at least five axes of rotation between the structure of the satellite and the thruster,
• (ii) at least two rigid offset arms, and
• (iii) at least three motor-driven links interconnecting said at least two rigid offset arms with said thruster, and
• wherein at least two of the motor-driven links allow rotation about two axes of rotation.
