The Global Positioning System (GPS) is the first 24-hour, all weather navigation system. Now available to boaters at an affordable price, GPS has become the predominant navigation system for boats; non-nautical applications are already in use. This second edition of a popular book will help owners get the best from their sets and make full use of the facilities available, whether simply position fixing and course setting or interfacing with radar, loran, autopilots, knotmeters, chart plotters, or video sounders.
The author explains how to use and interpret the data received, as well as how to test for accuracy and make necessary corrections. He also advises what to look for when buying a set, how to achieve optimum accuracy, and he unravels the jargon associated with instruction manuals.
Several of the most popular models are discussed, including Magellan, Raytheon, Valsat Explorer, Sportsman, and more.
