ESRL Science Making a Difference in Real-time GPS Positioning
Scientists at ESRL's Global Systems Division (GSD) are known for
transferring their advances in science and technology to
operations and have made exciting progress with a product called
NOAATrop. NOAATrop was developed to improve GPS positioning,
navigation and timing accuracy using real-time weather data. The
California Spatial Reference Center (CSRC) at Scripps
Institution of Oceanography recently started using NOAATrop for
real-time engineering applications in southern California. "This
is the first known operational application of a weather model
being used to improve high accuracy GPS surveying," said Seth
Gutman, NOAA scientist whose years of research at ESRL's Global
Systems Division in Boulder have made this advancement possible.
Almost everyone has heard of GPS - the satellite Global
Positioning System. GPS was developed by the U.S. Department of
Defense to tell us basically three things - where we are, how to
get where we want to be, and
