Can Single-Frequency RTK Still Be Used? Applications, Accuracy, and Limitations
RTK (Real-Time Kinematic) is widely used to achieve centimeter-level GNSS positioning in surveying, agriculture, robotics, UAV mapping, and machine control applications. Today, most high-performance RTK receivers support dual-frequency or multi-frequency...
