Efficient Implementation of a GNSS Base Station with RTK Receiver for Topography

Recently, low-cost dual-frequency receivers have been evaluated in various positioning applications due to their high-precision capabilities at an affordable cost, positioning them as viable alternatives to high-end geodetic GNSS devices. This research focused on the implementation of a GNSS base station with a Real-time kinematic (RTK) receiver for topographical applications. RTK differential corrections were configured using the u-blox ZED-F9P module, and tests demonstrated their effectiveness in providing accurate measurements in diverse environments. To validate the results, a commercial module was used, and the comparison showed insignificant errors in measurements. Therefore, this study promotes the adoption of low-cost dual-frequency GNSS receivers as viable solutions for high-precision topographical applications.
