The NOAA National Data Centers are responsible for the ingest, quality control, stewardship, archival storage of and public access to data and science information. The CLASS system is modeled to support the NOAA-adopted Open Archival Information System-Reference Model (OAIS-RM), which identifies high-level roles and responsibilities of various archival components and illustrates the connections between functional entities in order to fulfill archive requirements.\r\n\r\nCLASS is the NESDIS archive distribution infrastructure for the NGS NCN dataset.\r\n \r\n \r\n download\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n https://geodesy.noaa.gov/UFCORS/\r\n \r\n \r\n WWW:LINK-1.0-http--link\r\n \r\n \r\n NCN UFCORS\r\n \r\n \r\n User-Friendly NCN data download page.

NGS itself at an hourly or daily cadence, in accordance with Partner distribution and,\r\n\r\n2. NESDIS/NCEI archive via CLASS infrastructure. NCN data is harvested daily, but not distributed until 30 days hence.\r\n \r\n \r\n \r\n \r\n The National Geodetic Survey (NGS), an office of NOAA's National Ocean Service, manages a network of Continuously Operating Reference Stations (CORS) that provide Global Navigation Satellite System (GNSS) data consisting of carrier phase and code range measurements in support of three dimensional positioning, meteorology, space weather, and geophysical applications throughout the United States, its territories, and a few foreign countries. This is called the NOAA CORS Network (NCN)\r\nSurveyors, GIS users, engineers, scientists, and the public at large that collect GPS or GNSS data can use NOAA's CORS data to improve the precision of their positions. CORS enhanced post-processed coordinates approach a few centimeters relative to the National Spatial Reference System, both horizontally and vertically. \r\nThe NCN network is a multi-purpose cooperative endeavor involving government, academic, and private organizations. The sites are independently owned and operated. Each agency shares their data with NGS, and NGS in turn analyzes and distributes the data free of charge. As of February 2025, the NCN provides data from approximately 2,000 active sites. NCN data holdings to include decommissioned stations, comes to a total of 2,908 sites. These sites are contributed by over 230 different organizations, and the network continues to expand.\r\n\r\nThe DOI referenced is for the archived NCN data holdings.\r\n \r\n \r\n The NCN data set enables users to attain centimeter-level positioning for points of interest and can be used to measure crustal motion, moisture content for the lower atmosphere, enhance water level observations and total electron content (TEC) in the upper atmosphere.\r\n \r\n \r\n The NCN system benefits from a multipurpose cooperative endeavor involving NGS, many governmental, academic, commercial and private organizations who own and operate the bulk of the participating sites.\r\n \r\n \r\n onGoing\r\n \r\n \r\n \r\n \r\n NGS Communications and Outreach Branch\r\n \r\n \r\n \r\n \r\n \r\n \r\n (301) 713-3242\r\n \r\n \r\n (301) 713-4172\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n ngs.infocenter@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n NGS Communications and Outreach Branch\r\n \r\n \r\n \r\n \r\n \r\n \r\n (301) 713-3242\r\n \r\n \r\n (301) 713-4172\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n ngs.infocenter@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n custodian\r\n \r\n \r\n \r\n \r\n \r\n \r\n continual\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://geodesy.noaa.gov/CORS/images/baldnoaa.gif\r\n \r\n \r\n NOAA small logo\r\n \r\n \r\n \r\n \r\n \r\n \r\n EARTH SCIENCE\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Science Keywords\r\n \r\n \r\n \r\n 17.0\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Geodetic Control Theme\r\n \r\n \r\n NGDA\r\n \r\n \r\n National Geospatial Data Asset\r\n \r\n \r\n NGDAID48\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n NGDA Portfolio Themes\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n SOLID EARTH\r\n \r\n \r\n VERTICAL LOCATION\r\n \r\n \r\n place\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Location Keywords\r\n \r\n \r\n \r\n 20.8\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n GPS > Global Positioning System Satellites\r\n \r\n \r\n GROUND STATIONS > GROUND STATIONS\r\n \r\n \r\n GROUND-BASED OBSERVATIONS > GROUND-BASED OBSERVATIONS\r\n \r\n \r\n NAVSTAR > NAVSTAR Global Positioning System\r\n \r\n \r\n platform\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Platform Keywords\r\n \r\n \r\n \r\n 17.2\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n GPS : Global Positioning System\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n GCMD Instruments/Sensors Keywords\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Geodetic/Global Positioning\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n NOS Data Explorer Topic Category\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n DOC/NOAA/NOS/NGS > National Geodetic Survey, National Ocean Service, NOAA, U.S. Department of Commerce\r\n \r\n \r\n dataCentre\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Data Center Keywords\r\n \r\n \r\n \r\n \r\n 2017-04-24\r\n \r\n \r\n publication\r\n \r\n \r\n \r\n \r\n 8.5\r\n \r\n \r\n \r\n \r\n Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA)\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords\r\n \r\n \r\n GCMD Keyword Forum Page\r\n \r\n \r\n Global Change Master Directory (GCMD). 2024.

This includes the current global reference frame from the International GNSS Service, or IGS, and with respect to the National Spatial Reference System, NSRS, realizations of the North American Datum of 1983, NAD 83, as defined by NGS. Reference frames are updated periodically as according to policy: https://geodesy.noaa.gov/INFO/Policy/files/042011_CORS_Coordinate_Policy.pdf\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Conceptual Consistency\r\n \r\n \r\n To become part of the NOAA CORS Network (NCN), each station must meet NGS' station criteria standards and maintain its integrity. Data is quality controlled by NGS before it is distributed to the public. In addition, NGS publishes position and velocity values for each CORS in both the global reference frame and in the National Spatial Reference System. More information can be found at https://geodesy.noaa.gov/PUBS_LIB/CORS_guidelines.pdf\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n NCN data is processed by NGS operations at an hourly or daily cadence, dependent a particular stations' retrieval frequency. Hourly data is deleted from Partners are deleted two days after daily file is created. Hourly data from NGS-owned stations are kept.\r\n\r\nNCN data is harvested daily by NESDIS/NCEI, and then archived after a 30-day period, and distributed via the NCEI archive at the Comprehensive Large Array-data Stewardship System (CLASS).\r\n \r\n \r\n \r\n \r\n GPS or GNSS data that are received in either binary or Receiver INdepedent EXchange (RINEX) format, and are processed by NGS into a compressed daily RINEX formatted file.
