This paper describer the beamwalk system of the Starlab experiment. A functional description is followed by a brief description of the optical layout. The control system is covered in more detail. The Stralab beamwalk control system commands one mirror servo with feedback from the beamwalk translation sensor and commands the other mirror servo with feedback from the beamwalk angle sensor. Servo Compensation is applied to each loop to achieve the desired stability. The advantage and disadvantage of controlling both mirrors with combined angle and translation sensor signals is addressed.
