AZUP (AZ)

AZUP is a permanently operating GNSS CORS reference station in Maricopa County, Arizona, operated by NOAA's National Geodetic Survey as part of the NGS_CORS network. The station tracks GPS and GLONASS constellations, providing real-time RTK corrections and archival data for static post-processing surveys. Surveyors can achieve centimeter-level accuracy for positioning and mapping applications.
