NOAA/NGS Continuously Operating Reference Station (CORS)

Dataset Identification:

Resource Abstract:
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. Surveyors, GIS users, engineers, scientists, and the public at large that collect GPS data can use 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. The CORS 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 March 2014, the CORS network contains almost 2000 stations, contributed by over 200 different organizations, and the network continues to expand. The National Geophysical Data Center (NGDC) is the designated archive of the NGS CORS data set. NGDC utilizes NOAA's Comprehensive Large Array-data Stewardship System (CLASS) infrastructure to archive and distribute CORS data.

purpose:
The CORS 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, and total electronic content in the upper atmosphere. NGS publishes coordinates for CORS in several reference frames. This includes the current global reference frame from the International GNSS Service (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: http://geodesy.noaa.gov/INFO/Policy/CORS-coordinate-policyv4_20Dec2011.pdf

Additional information on resource:
The United States operates the Global Positioning System (GPS). The term Global Navigation Satellite Systems (GNSS) has been created to reference all navigation satellite systems. GNSS encompasses the U.S. GPS system, the Russian Federation GLONASS system, and any future systems such as Europe's Galileo or China's Compass.
Credits:
NGS coordinates a network of CORS stations from approximately 200 organizations such as federal, state, and local governments, academia, the private sector, and international groups.

Resource lineage description
Lineage statement
GNSS observational data from the CORS network are ingested, translated, and processed by NGS and are posted to the NGS online servers as hourly or daily files, and ultimately retained as daily files in RINEX format. After 30 days, data in the at-sampling rate is copied to the NGDC archive, and NGS online holdings are then decimated to a 30-second sampling rate. Special use case: Certain groups such as the Federal Aviation Administration, the U.S. Coast Guard, NOAA's Earth System Research Laboratory (ESRL), and NGS, make GNSS data available in binary format to NGS. These data are used as input to algorithms for internal NOAA models such as the US-Total Electron Content product and to produce GPS Meteorology Water Vapor measurements. NGDC, not NGS, has decided to archive the raw data from these GPS stations as a daily tar file consisting of hourly binary files

evaluation Method Description  The vertical coordinates of the GPS site, specifically the GPS antenna location, are accurate to about 2 centimeters once biases are removed.
Completeness Commission
evaluation Method Description  Data written to the NGDC archive is reviewed for completeness. Automated routines perform daily checks for file names and file sizes, and also aided by the internal checksum of GNU zip compression as data is written to tape. Any faulty data is removed from the archive.
ConceptualConsistency
measure Description  To become part of the CORS network, each site must pass through NGS' site criteria standards and maintain its integrity. Automated routines at NGDC pull data staged by NGS at regular intervals.
