Safety Improvement Test of A GPS Based AGV System Using A Dead Reckoning Algorithm

    Global positioning system(GPS)technologies have recently led to innovations in the guidance area of small mobile robots．In particular。the design of guidance and navigation systems for autonomous guided vehicles(AGVs)has included a carrier phase differential GPS(CTY．3PS)．With a single inexpensive GPSreceiver，CI)GPS technology can measure the position of a vehicle with all elTor of jlist a few decimeters．Comparison with the reference traiectory and the test result，the elTor on the driving position of a CIX；PS-based AGVis
