The authors present two techniques that enhance the applicability of pseudorandom absolute position measurement as a cost-effective upgrading feature for industrial automated guided vehicles (AGVs). An onboard synchronization technique for code track scanning leads to minimum complexity requirements for the tracks physically laid on the floor: on a 1-bit-wide pseudorandom code track has to be added to the obvious guide path. An optimized serial/parallel implementation of the pseudorandom/natural code conversion allows the best design tradeoff to be made between the cost of the equipment and the time
