In this paper, the position of a mobile robot using DGPS (differential GPS) and UPS (ultrasonic positioning system) is measured and the performance of UPS is analyzed using DGPS. UPS is absolute positioning system using ultrasonic waves and has better performance in low price than the other absolute positioning systems. So in order to evaluate the performance, UPS is compared with the RTK (real-time kinematics) method, which is of the most accurate methods in the DGPS. As a result, the possibility of using UPS can be discussed as pseudolites or pseudosatellites in the place where GPS is not available.
