Global Positioning Systems

Government GPS Sites:

• National Park Service GPS Site
  This site contains quite a bit of background information and a number of good links to technical GPS information. There is a history of GPS, a good semi-technical description of GPS, links to base station information and UTM zone maps, government contacts and various tools and training information.
• U.S. Forest Service GPS Home Page
  This site contains a great deal of practical background information. The report on "GPS to GIS - the Complete Guide" is particularly comprehensive but the 'GPS Myths' and 'Data Transformation' reports also contain good information.
• U.S. Coast Guard GPS information (Navigation Center)
  The Coast Guard Navigation Center (NAVCEN) serves as the civilian interface to the Department of Defense on GPS operations and management. There is a tremendous amount of technical information at this site.
• Global Positioning System (GPS)
  U.S. space-based radionavigation system, developed by National Space-Based Positioning, Navigation, and Timing Coordination Office and hosted by the U.S. Coast Guard Navigation Center.
• USGS Biological Resources GPS Site
  This site maintains DOI GPS items including information on the PLGR military GPS units.
• Department of Defense NAVSTAR Global Positioning Systems
  This is a military site with some information on the GPS satellite system.
