Real-Time Kinematic (RTK) GNSS receivers represent one of the most advanced technologies in satellite-based positioning systems. Unlike traditional Global Navigation Satellite System (GNSS) receivers, which provide meter-level accuracy, RTK receivers achieve centimeter-level precision by using correction data from a base station. This leap in accuracy has transformed industries ranging from...
