Abstract : The patent relates to an improved system for sensing the disturbance forces on a spacecraft. An unsupported mass is shielded by the spacecraft from external non-gravitational forces, allowing the mass to travel in a purely gravitational orbit. A sensor system responds to motion of the spacecraft relative to the unsupported mass and activates thrusters which force the spacecraft to follow the unsupported mass without touching it. Movable masses or chargeable magnets on three orthogonal axes are mounted in the spacecraft to compensate for the attraction between the mass and other components located within the spacecraft.
