NOAA CLASS archive: Continuously Operating Reference Stations (CORS)Entry ID: gov.noaa.class.CORS
Abstract: ABSTRACT: The National Geodetic Survey (NGS), an office of NOAA's National Ocean Service (NOS), coordinates a network of geodetic-quality CORS stations that provide Global Positioning System (GPS) carrier phase and code range measurements in support of 3-dimensional positioning activities throughout the United State and its territories. The positions of these CORS sites help define the National ... Spatial Reference System (NSRS). NGS defines and manages the NSRS - the framework for latitude, longitude, height, scale, gravity, orientation and shoreline throughout the U.S. The NSRS provides a consistent national coordinate system to support mapping, charting, navigation, boundary determination, property delineation, infrastructure development, resource evaluation surveys, and scientific applications. The CORS system enables positional accuracies that approach a few centimeters relative to the NSRS, both horizontally and vertically.
SUPPLEMENTAL INFORMATION: 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.
