Abstract
The present invention provides an X-Y gimbal that eliminates the keyhole problem--a problem which occurs when a payload mounted on the X-Y gimbal is required to be pointed at a direction which is close to co-linear to the gimbal's Y axis. The preferred embodiment provides for a rotation around the Z axis of both the X and Y gimbals as the target approaches a predetermined proximity to co-linearity with the Y axis. An alternate embodiment provides for a predetermined tilting of the Y axis gimbal. Both inventive embodiments provide uninterrupted and continuous tracking of a target without expensive electric and/or electromagnetic energy transferring slip-rings and rotary joints.
