RTK (Real-time Kinematic) positioning is one of the satellite-based positioning method which enables the three dimensional positioning with 20mm accuracy. However, it is difficult to keep the high accuracy continuously while moving, because the interruption of the satellite signals causes the decline of RTK accuracy, and the initialization time is required to restore the high accuracy. In the study the system to evaluate the availability of RTK positioning while moving has been developed by constructing the method to simulate the initialization time and the change of the accuracy.
