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 ... View entire text

Purpose: PURPOSE: NGDC archives the CORS data set as per the NOAA/NOS Records Disposition Schedule, section 1602-12.

Quality ATTRIBUTE ACCURACY REPORT: The carrier phase observations are accurate to a few centimeters, once biases have been removed.

LOGICAL CONSISTENCY REPORT: 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.
