Marine GPS navigation systems , regardless of electrical engineering, computer technology, or component makeup, all essentially function the same way. The device you install in your craft actually communicates with a satellite network launched by the US Defense Department in 1978 called the Global Positioning System, or GPS for short. Marine GPS units can be used while boating, deep sea fishing, fleet tracking, and various other marine applications.
