The invention discloses a high-rigidity and high-damping satellite platform configuration, which belongs to the field of overall design of spacecrafts and comprises a satellite-rocket butt joint ring used for being in butt joint with a rocket adapter; a mounting plate, wherein one side of the mounting plate is fixedly connected with the satellite-rocket butt joint ring, the other side of the mounting plate is fixedly connected with an optical load plate, and the optical load plate bears an optical load; damping layers which are laid on the outer surface of the optical loading plate and the outer wall of the satellite-rocket butt joint ring; a restraint layer which is laid on the outer surface of the damping layer; the mounting plate comprises a butt joint plate, a partition plate, an outer plate and an optical load plate; the partition plate is of a #-shaped structure, the outer plate is arranged on the periphery of the partition plate, the butt joint plate, the partition plate, the outer plate and the optical load plate are all aluminum honeycomb sandwich plates, and embedded parts are embedded in the single-machine equipment installation position and the rigidity reinforcing position of the aluminum honeycomb sandwich plates. The high-rigidity and high-damping satellite platform configuration has advantages of convenient single equipment configuration and installation, and high space utilization ratio. On the premise that the system is high in rigidity and small in additional mass, structural damping is effectively increased so as to attenuate vibration response of all components of the system.
