GPSRTK
GPS Real-Time Kinematic (GPS-RTK) is a GNSS positioning technique that delivers centimeter-level accuracy by applying real-time carrier-phase corrections to a rover’s GPS observations. It relies on a base station with a precisely known position to compute corrections and transmit them to rovers in real time.
In operation, the base collects GNSS data and generates corrections, which are sent via radio, cellular, or
RTK systems commonly use RTCM-formatted corrections and can operate as a single-base setup or as part of
Accuracy varies with conditions but is typically in the range of 1–3 centimeters horizontally and a few
Applications include land surveying, construction and civil engineering, precise mapping, agriculture, mining, and autonomous navigation. GPS-RTK
