The National Geodetic Survey (NGS) recently hosted a special guest at their Corbin Training Center in Richmond, Virginia. NGS, part of the Ocean Service, manages the National Spatial Reference System.
This system provides highly accurate positioning data by joining together ground-based reference stations with satellite-based Global Positioning System (GPS) technology to develop what is called the Continuously Operating Reference Station (CORS) network. Here, Santa checks out one of NOAA's more than 1,100 CORS stations around the nation.
Tune in to the latest edition of Making Waves, the weekly NOS podcast, for more about how NGS helps Santa find his way around the nation.
