broadcast ephemeris Continuously Operating Reference Station (CORS) earth observation geospatial GNSS GPS mapping NOAA CORS Network (NCN) post-processing RINEX survey
The NOAA Continuously Operating Reference Stations (CORS) Network (NCN), managed by NOAA/National Geodetic Survey (NGS), provide Global Navigation Satellite System (GNSS) data, supporting three dimensional positioning, meteorology, space weather, and geophysical applications throughout the United States. The NCN is a multi-purpose, multi-agency cooperative endeavor, combining the efforts of hundreds of government, academic, and private organizations. The stations are independently owned and operated. Each agency shares their GNSS/GPS carrier phase and code range measurements and station metadata with NGS, which are analyzed and distributed free of charge. NGS provides access to all NCN data collected since 9 February (040) 1994.
