Abstract
An apparatus for rotation rate damping of a suspended platform, the apparatus including a plurality of vertically-extended partially-filled fluid reservoirs, each of the reservoirs being open at a top and offset from a center of gravity of the suspended platform, the reservoirs being connected by tubing permitting fluid to flow between reservoirs in response to gravitational accelerations; wherein motion of the fluid in the tubing creates damping of the rotational motion of the platform.
