Electronic chartplotters are by nature processor intensive. They need to retrieve the GPS signal and overlay that on a map updating every few milliseconds. Some GPS software can run on standard computers, but most of the higher end is dedicated equipment. Especially when the chartplotter generates three-dimensional displays, as used for fishing, considerable processing power and video memory canmay be neededrequired.

As with all marine systems, chart-plotters generally are not used alone. In commercial ships, they are integrated into a full system of marine instruments that can guide the ship under any conditions. These other instruments include Sonar transducers, integration with 2 Way Radio communication devices and emergency locators (EPIRB).
