The efficient infrastructure inspection requires low-cost and high-precision positioning and 3D measurement technologies. In this paper, we focused on single-frequency precise point positioning (PPP) and single-frequency RTK-GNSS positioning to improve the positioning accuracy with low cost devices. Moreover, we focused on the performance of the antenna on positioning accuracy. First, we evaluated the positioning performance of PPP and single-frequency RTK-GNSS positioning with the same GNSS antenna. Second, we evaluated the positioning performance of GNSS antenna on positioning accuracy, using a low-cost GNSS antenna and professional GNSS antenna for surveying. Third, we conducted outdoor experiments to simulate bridge inspection work. Through our experiments, we verified that single-frequency RTK-GNSS positioning can be used for the improvement of positioning performance in infrastructure inspection work.
