How GPS and Cartography Work
Your 100 Series
TM
Fishing System also supports GPS and chartplotting, and uses GPS and
sonar to determine your position, display it on a grid, and provide detailed underwater
information. The Global Positioning System (GPS) is a satellite navigation system
designed and maintained by the U.S. Department of Defense. GPS was originally
intended for military use; however, civilians may also take advantage of its highly
accurate position capabilities, typically within +/- 10 meters, depending on conditions.
This means that 95% of the time, the GPS receiver will read a location within 10 meters
of your actual position. Your GPS Receiver also uses information from WAAS (the Wide
Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay
Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
