The invention provides a satellite with ultrahigh pointing accuracy and ultrahigh stability under dynamic-static isolation and principal-subordinate cooperative control, which comprises a non-contact magnetic-suspension mechanism disposed between a platform cabin and a load cabin, wherein the non-contact magnetic-suspension mechanism comprises a rotor and a stator which are matched; the rotor is installed in the platform cabin, and the stator is installed in the load cabin; and the dynamic-static isolation between the load cabin and the platform cabin is realized by the rotor and the stator. By adopting a brand-new idea and a brand-new method of the spatial dynamic-static isolation and the principal-subordinate cooperative control, applying a control idea based on a complete pose decoupling configuration and a slip form layer, and using the non-contact magnetic-suspension mechanism with high accuracy and high bandwidth, the satellite pose pointing accuracy is higher than 5*10-4 DEG/SEC, the pose stability is higher than the ultrahigh accuracy of 5*10-6DEG/SEC, a technical difficulty about the ''ultrahigh accuracy and ultrahigh stability'' is thoroughly solved, and a load pose can be completely measured and controlled.
