Abstract
GPS-RTK technology has been currently used in the mapping area. But this technology cannot comprehensively utilize in urban surveying, owing to the influence of inaccuracy measurement. In this paper, the quality control measurement of GPS-RTK are tested and analyzed. Compared to the general instruments, GPS-RTK method could eliminate the error. The maximum errors between points were 5.727, and all the points were not beyond tolerance. According to the measurements results, 96.3% points were with the scope of 5 cm, and the root-mean-square error (RMS) were also in the limit of measurements. This paper pointed out the two times initial quality control method, it is effectively to control the gross error, enhance the accuracy of GPS-RTK technology. From the results, the quality control measurement of GPS-RTK could provide more accuracy and reliability on surveying.
