Platform stabilization system
First Claim
1. A platform stabilization system for isolating a payload from motion of a supporting structure, the platform stabilization system comprising:
- a support frame;
a platform for carrying a payload;
a plurality of isolators each extending directly between the support frame and the platform;
each isolator permitting linear movement of the platform relative to the support frame with three degrees of freedom;
each isolator permitting rotational movement of the platform relative to the support frame with three degrees of freedom;
the plurality of isolators cooperating to form an isolation array supporting the platform directly within the support frame;
the isolation array spacing the platform from the support frame;
the isolation array permitting limited linear movement of the platform relative to the support frame with three degrees of freedom along three orthogonal platform axes;
the isolation array permitting limited rotational movement of the platform relative to the support frame with three degrees of freedom about the three platform axes;
the isolation array being substantially more resistant to linear movement of the platform relative to the support frame than to rotational movement of the platform relative to the support frame;
wherein the platform is not rotationally constrained by the isolation array; and
wherein the isolation array has an undamped natural frequency for linear movement of the platform along the platform axes that is at least two times an undamped natural frequency for rotational movement of the platform about the platform axes.

Abstract
A platform stabilization system comprises a support frame, a platform and a plurality of isolators each extending directly between the support frame and the platform. Each isolator permits linear movement of the platform relative to the support frame with three degrees of freedom and permits rotational movement of the platform relative to the support frame with three degrees of freedom. The isolators cooperate to form an isolation array supporting the platform directly within, and spacing the platform from, the support frame. The isolation array permits limited linear movement of the platform within the support frame with three degrees of freedom and permits limited rotational movement of the platform relative to the support frame with three degrees of freedom. The isolation array is substantially more resistant to linear movement of the platform than to rotational movement of the platform and does not rotationally constrain the platform.
