RTK

Real-Time Kinematic (RTK) is a GNSS positioning method designed for high-accuracy location measurements in demanding geospatial workflows. It combines satellite positioning with correction information from a nearby reference station or GNSS correction network to improve the accuracy of coordinates in real time. RTK technology is commonly used with survey-grade GNSS receivers, drones, construction equipment, and mobile mapping systems. It supports applications such as topographic surveying, cadastral mapping, drone photogrammetry, precision agriculture, utility mapping, and construction layout. By correcting common GNSS errors, RTK can provide centimeter-level positioning when appropriate satellite coverage, correction services, and field conditions are available. RTK workflows can also reduce the need for extensive ground control and improve the consistency of collected spatial data, making the technology valuable for professionals working with accurate geographic coordinates and location-based measurements.
