ABSTRACT:
A low profile, low cost pointing mechanism for an imaging system. The inventive pointing mechanism (500) includes a mechanism (502, 504) for supporting the imaging system so that it is movable from a first pointing angle to a second pointing angle. A second mechanism (570, 580, 584, 542) is included for driving the supporting mechanism (502, 504) to change the pointing angle thereof in response to signals from a control system. In a preferred embodiment, the inventive pointing mechanism (500) includes a tilt gimbal (502) located at the center of gravity of the imaging system and a pan gimbal (504). The pan and tilt gimbals (502, 504) are driven by pan and tilt stepper motors (542, 526) in response to commands from a joystick (568) on a remote control unit (566).
