933 online resource text und In support of the environmental data collection by the National Oceanic and Atmospheric Administration's (NOAA's) Geostationary Operational Environmental Satellites (GOES), a time code has been incorporated into an interrogation message from these satellites by the National Bureau of Standards (NBS). This message is directed to data-collection platforms engaged in seismic, tsunami, hydromet and other related monitoring activities. The NBS has developed this time-code system to serve environmental data users who require only a few tenths of a second accuracy as well as those who need a more accurate time reference. The time code is available continuously from two geostationary satellites and provides a coverage of the Atlantic and Pacific Ocean Basins as well as the North and South American Continents. The time code includes the necessary information to compensate for free-space propagation delays between the master clock located at Wallops Island, Virginia, and the user. Preliminary results indicate a timing resolution of 10 microseconds. J. V. Cateora. 1978. Title from PDF title page. Includes bibliographical references. Mode of access: World Wide Web.
