The Accuracy Analysis and Usability of Low Cost RTK Portable Kit on Surveying Aims

Thanks to the rapid developments in electronics, computers, and software, state-of-the-art and cost-effective devices are emerging in almost every area. One of these areas is GNSS technologies and related devices. These advances in GNSS devices enable users to provide more advanced and more accurate results at an affordable cost, and thus the use of these devices is increasing rapidly. This study investigated the accuracy performance supplied by the cost-effective ArduSimple CORS system. For this purpose, ArduSimple RTK Calibrated Surveyor Kit and Topcon HiperV GNSS receivers were connected to the Tusaga-Aktif system at 86 points. Real-time position information was collected three different times with 30 epochs of both GNSS receivers. The coordinate data obtained from Topcon and ArduSimple GNSS receivers were compared, and the accuracy performance provided by the ArduSimple system was evaluated. In this study, the coordinate data obtained with the Topcon receiver, whose accuracy is known and tested many times, are accepted as a reference. When the difference values are averaged, it is seen that the position accuracy obtained from the ArduSimple receiver is 1.2 cm in the easting, 1.4 cm in the northing, and 5 cm in height.
