Abstract
Stabilization apparatus for aiming an instrument such as a camera at a target object. Rotational rate sensors mounted on the camera platform detect rotation of the platform from an initial position about roll, tilt and pan axes. The sensor output signals are applied to torque motors for rotating the platform back to its initial position. A hub assembly supports the camera platform for rotation about roll and tilt axes, and a yoke supports the hub assembly for rotation about a pan axis. The yoke is adapted for suspension from a support vehicle such as a helicopter, and it supports the platform for unimpaired rotation within windowed outer and inner domes. The outer dome is rotatable about a pan axis and the inner dome is rotatable about an inclined tilt axis. The arrangement reduces the size of the window opening from the camera to the exterior, which correspondingly reduces wind loads acting against the interior of the domes.
