Platform stabilization system

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;
• and
• wherein the platform is not rotationally constrained by the isolation array.
