I'm not sure what your question is, but here's a guess:
GPS has completly taken over navigation in the marine field. Almost every pleasure boat and certainly every commercial ship has a GPS aboard. It is to the point now that traditional sailing navigation measures.....paper charts, speedometers, celestial navigation....are used less and less and,at a guess, 50% of private boaters would be lost if their GPS systems stopped working.
GPS is also now interfaced with elctronic charts so you can have a dot moving across a chart to show where you are......

The applications are numerous. By far the biggest is the accuracy of ships position. By knowing this it allows for Satellite communication, electronic chart use, accurate surveys, television reception, and with the right helm controls dynamic positioning (keeping a vessel in one spot on the ocean within just a few feet).
On my ship we have 4 GPS recievers and 11 pieces of equipment use the GPS signal.

Ditto on the first answer. All I can add is that you can buy a car or boat GPS. It is important to take navigation courses and carry paper charts as sometimes electronics fail.
