A stabilized platform for use in connection with a satellite antenna mounted to a ship, comprising: a platform mounted on a gimbal joint which is adapted to be supported upon a ship; the platform being mechanically coupled to an antenna such that stabilization of the platform will tend to stabilize the antenna and tend to maintain the pointing of the antenna generally in a fixed direction during pitch and roll motions of the ship; an acceleration displaceable mass adapted to compensate for linear acceleration, the acceleration displaceable mass having an initial position in the absence of linear acceleration; the platform, the acceleration displaceable mass, and the antenna forming a substantially balanced structure when the acceleration displaceable mass is in said initial position, the structure having a center of gravity located below the gimbal joint; the acceleration displaceable mass being operable to reduce forces due to linear acceleration tending to destabilize the platform, the acceleration displaceable mass being operable to move to a displaced position, which is spaced from said initial position, in response to linear acceleration of the structure formed by the platform, the acceleration displaceable mass and the antenna, the acceleration displaceable mass being operable to generate an opposing torque when the acceleration displaceable mass moves to its displaced position such that the opposing torque tends to offset the destabilizing forces due to linear acceleration; the acceleration displaceable mass including a pendulum supported by the platform, where the pendulum is operable to reduce destabilization of the platform caused by linear acceleration forces by moving to a displaced position in response to linear acceleration of the structure formed by the platform, the pendulum and the antenna, the pendulum being operable to generate an opposing torque when the pendulum moves to its displaced position such that the opposing torque tends to offset the destabilizing effects of linear acceleration, the pendulum being operable to return to an initial position when the platform is at rest; and, the pendulum having a weight “Wa”which is substantially equal to the product of the total weight of the structure supported upon the gimbal joint “Ws”times the offset “h”of the center of gravity of said structure, all divided by the length “o”of said pendulum.
