How GPS and Trackplotting Work
Your Humminbird® 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 4.5 - 10 meters, depending on conditions and your Humminbird®
model. This means that 95% of the time, the GPS receiver will read a location
within 4.5 - 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.
GPS uses a constellation of satellites that
continually send radio signals to the earth. Your
present position is determined by receiving signals
from up to 16 satellites and measuring the distance
from the satellites.
All satellites broadcast a uniquely coded signal
once per second at exactly the same time. The GPS
receiver on your boat receives signals from
satellites that are visible to it. Based on time
