According to one example of the invention, a drill rod handler includes a movable clamp. A position sensor system for the drill rod handler includes a level sensor that is configured to detect a position of the moveable clamp with respect to gravity. The position sensor system further includes a rotation sensor configured to detect a rotational position of the moveable clamp with respect to a defined axis that runs parallel to gravity. Furthermore, the position sensor system includes a control center that is communicably connected to the level sensor and the rotation sensor.
