NGS Releases More Accurate Coordinates for NOAA's Permanent GPS Network

Friday September 20, 2019

NGS completed a major reprocessing of 22 years of data from 3,050 worldwide permanent GPS reference stations to improve coordinates at 2,000 NOAA Continuously Operating Reference Stations (CORSs) around the U.S. and its territories. The effort, called the Multi-Year CORS Solution 2, aligns the U.S. National Spatial Reference Frame to the newest International Terrestrial Reference Frame of 2014. The update provides improved accuracy and consistency in the U.S. framework for referencing high-accuracy positions for use by the surveying, mapping, and geospatial communities. These more accurate coordinates were integrated into NGS' popular online positioning software tools (OPUS) for direct use by customers, and into NGS' data products for use by operators of other national and local GPS networks.
