Abstract

Two Wide Area Augmentation System (WAAS) satellites are now transmitting the standard L1 and L5 carriers and codes of the Global Positioning System (GPS). Since these are geostationary satellites, it is possible to aim a parabolic dish at one and obtain high-gain, low-multipath interference signals without interruption. Such high-gain dishes, along with appropriate GPS receivers, were set up at three timing laboratories in North America: the National Institute of Standards and Technology in Boulder, Colorado, U.S.A., the United States Naval Observatory (USNO) in Washington D.C., U.S.A., and the National Research Council (NRC), Ottawa, Ontario, Canada. We report the results of this experiment over a 104 d period: January 1 to April 14, 2008, though with several significant outages, and other clock/data problems.
