| 摘要 |
The invention pertains to a propulsion system for the orbital control of a satellite with terrestrial orbit travelling with a speed of displacement along an axis V tangential to the orbit. It comprises two propulsion assemblies (50a; 50b), fixed to the satellite facing one another with respect to the plane of the orbit, each of the propulsion assemblies comprising two propulsion modules; each of the propulsion modules successively comprising: - a motorized link (51a) for rotation about an axis (R1a) parallel to the axis V, - an offset arm (52a), and - a platen (53a) supporting a propulsion unit (54a) able to deliver a thrust oriented along an axis perpendicular to the axis V, the two propulsion modules of each propulsion assembly being linked to the satellite on either side and substantially at equal distances from a plane P perpendicular to the axis V passing through a centre of mass CM of the satellite. |
