• We have examined positioning availability and accuracy of OmniSTAR, a wide area DGPS service, and StarFire, a global DGPS service, comparing with RTK and the DGPS service by Japan Cost Guard (JCG) . The experiments were for utilization of GPS in urban area. There were four experiments, i.e. fixing antennas on known points, carrying antennas by hands and brief stop on known points, revolving antennas, and carrying antennas by a vehicle. Accuracy of StarFire and OmniSTAR are not higher than the JCD's DGPS, large errors were sometimes observed for StarFire. Availability of DGPS is much higher than RTK. But availability of OmniSTAR was sometimes decreased by microwave wireless facilities.
