GRNX (AK)

GRNX is an NGS CORS reference station located in Denali Borough, Alaska, operated by NOAA's National Geodetic Survey. It tracks GPS and GLONASS constellations to provide real-time RTK corrections and archival data for static post-processing and baseline determinations. Surveyors can achieve high-precision positioning for control establishment, mapping, and deformation monitoring across the region.
