NOAA to track GPS satellites

The National Oceanic and Atmospheric Administration has announced it will lead an international effort to pinpoint the locations of more than 40 global positioning satellites currently orbiting the Earth. The project is aimed at ensuring the accuracy of GPS data used by the public and private sectors.

Staff members at NOAA's National Geodetic Survey (NGS) will use data collected at 10 analysis centers around the world to analyze satellite orbit data over the next four years.

NGS will coordinate information provided by the International Global Navigation Satellite Systems Service, a voluntary federation of more than 200 organizations that provide continuous global satellite-tracking data. The organization includes the U.S.-based Global Positioning System, the Russian GLONASS system, and the upcoming European Galileo system.

'For GPS receivers to provide accurate information, the precise location of positioning satellites as they orbit the Earth must first be determined,' explained NGS director David Zilkoski. 'NOAA looks forward to leading this international partnership to produce the highest quality satellite position data possible.'
