Embodiments of the present invention comprise devices, systems, and components for use with a survey pole positioning system. The system further includes a control unit that shifts, byte by byte, Q data units from the queue during a first system clock cycle, where Q<P, and sends, during the first system clock cycle, the Q data units to a processing device configured to process a maximum of Q data units per system clock cycle. Emisions of CO2 and NOx can be reduced.
