The Utah Reference Network (TURN) is a high-precision global navigation satellite system (GNSS) reference network providing real-time corrections and data for post processing. Our network consists of permanently located GPS receivers installed across Utah and portions of Idaho, Wyoming, and southern Nevada that generate real-time, high-accuracy GNSS positioning. These receivers send their data using the Networked Transport of RTCM via Internet Protocol (NTRIP) to a central system that analyzes the input to adjust and correct the data to provide the most accurate locations, usually down to centimeter level. Our network uses the Trimble Pivot VRS Platform.
