초록

Space-Based Augmentation System (SBAS), which is one of the GPS augmentation systems, is a Wide-Area
Differential GPS that provides differential GPS corrections and integrity data. In this study, we did performance
analysis of kinematic SBAS surveying by conducting Real-Time Kinematic (RTK), DGPS, standalone, and SBAS
surveys. Considering static survey results as truth, 2-D Root Mean Square (RMS) error and 3-D RMS error
were computed to evaluate the positioning accuracy of each survey method. As a result, the 3-D positioning
error of RTK was 13.1cm, DGPS 126.0cm, standalone (L1/L2) 135.7cm, standalone (C/A) 428.9cm, and SBAS
109.2cm. The results showed that the positioning accuracy of SBAS was comparable to that of DGPS.
