Coordinate Acquisition and Comparison of A Low-cost Multi-band GNSS Receiver with Total Stations; 멀티밴드 지원 저가형 GNSS 수신기의 좌표 취득 및 토탈스테이션과 비교

초록

This study analyzes the accuracy and applicability of a low-cost GNSS receiver based on a set of experimental results. Currently, GNSS (Global Navigation Satellite System) is mostly used not only in real life such as smartphones and navigation, but also in the field of surveying along with total stations and drones. In this study, an area of Yangjeon-ri, Gaejin-myeon, Goryeong-gun, Gyeongsangbuk-do was observed with a low-cost GNSS module. We chose terrain with road under construction, the structure of a fence, bank etc, appropriate topography and measured the sites using total stations and a GNSS receiver. The acquired coordinates were compared and analyzed. As a result of the analysis, the coordinates were matched from two points of the same reference point and errors of the GNSS receiver with reference to the total station ranged from 0.001m to 0.111m. This satisfies the relevant laws and regulations in the scale 1:1200 and shows a high possibility of utilization that can replace the total station. © 2024 Korean Society of Surveying.
