NOAA Continuously Operating Reference Stations (CORS) Network

The National Geodetic Survey (NGS), an office of NOAA's National Ocean Service (NOS), coordinates a network of Continuously Operating Reference Stations (CORS) that provide Global Navigation Satellite System (GNSS) data in support of a broad spectrum of engineering, scientific, and safety applications in the U.S. and its territories.

Through a submission agreement with NGS, NCEI archives the CORS dataset per the NOAA/NOS Records Disposition Schedule, section 1602-12.
