ZTL4 (GA)

ZTL4 is a dual-frequency GNSS CORS reference station operated by NOAA's National Geodetic Survey in Hampton, US, tracking GPS and GLONASS constellations. Surveyors can utilize this station to obtain real-time RTK corrections for centimeter-level positioning accuracy, conduct static post-processing for high-precision control surveys, and perform differential GNSS applications requiring reliable geo
