ABSTRACT:
A gimbal control system including a hand controller having a trackball and a mode select switch for determining the mode of gimbal control. The mode control switch is capable of selecting between four different control modes. The trackball is enabled to control movement of the gimbal in different control relationships depending on the control mode which is selected. The hand controller includes a plurality of other switches for enabling the trackball to provide additional system control capabilities. The hand controller is ergonomically designed to minimize operator stress and fatigue during extended missions. It has a particular shape and the various control elements are strategically positioned to provide ready access to an operator's manual digits when the controller is held in the right hand with both hands and arms in a naturally relaxed attitude oriented at approximately a right angle.
