This paper describes the operational coverage at the phase III Global Positioning System (GPS) for the full 18 satellites plus three spare satellites in Japan. The result is that there will be one or two poor accuracy periods in Japan after the GPS schedule is completed. The position accuracy can be obtained by multiplying the user equivalent range error by a position dilution of precision (PDOP). It should be noted that this estimate of accuracy is for a point solution to the GPS ranging equations and can be improved with the kalman filter. The kalman filter will be particularly effective in reducing the random errors. It has been demonstrated that the reducing factor is at least 1/3 by computer simulations.
