Cooperative CORS Data - Base Station
The National Oceanic and Atmospheric Administration (NOAA) Continuously Operating Reference Stations (CORS) Network (NCN) provide Global Navigation Satellite System (GNSS) data, supporting 3-D positioning, meteorology, space weather and geophysical applications throughout the country.
Surveyors, GIS users, engineers, scientists and others who collect GPS/GNSS data use NCN data acquired at fiducial geodetic control stations. People use the data to improve the precision of their positions and align their work within the National Spatial Reference System (NSRS). NCN enhanced post-processed coordinate accuracies can approach a few centimeters, both horizontally and vertically.
The CORS network is a cooperative effort involving government, academic and private organizations. The sites are independently owned and operated. Each agency shares its data with NGS. NGS analyzes and distributes the data free of charge. As 2014, the CORS network had over 1,900 stations, contributed by over 200 different organizations.

STATION DATA FILES: Files are moved to the web server daily and are stored as .zip files. Each file contains 24 hours of observations. File names are a composition of station name (JIME), IGS day number (i.e. 332 equal to 332nd day of the year), and 'O' for 'Observations').
