RTK (Real-Time Kinematic) GPS

Real-Time Kinematic (RTK) is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems like GPS (Global Positioning System). Unlike standard GPS systems, which typically offer accuracy in the range of meters, RTK can provide centimeter-level accuracy. This is achieved by leveraging a fixed base station in a known location that transmits correction data to one or more mobile receivers. These corrections allow the mobile units to adjust their position calculations and achieve high-precision location data in real-time.
