GPS was originally intended for military use; however, civilians may also take
advantage of its highly accurate position capabilities, typically within +/- 4.5
meters, depending on conditions. This means that 95% of the time, the GPS
receiver will read a location within 4.5 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.
The following GPS functionality is currently supported by the Fishing System:
• View current position
• View current track (breadcrumb trail)
• View precision speed and heading from your GPS receiver
• Save tracks, waypoints, and routes
• Travel a route and navigate from one waypoint to the next.
See Chart View and SD Memory Card Slots: Add Maps to Your Fishing
System for more information.
