GPS Navigation Systems
The Global Positioning System (GPS) utilizes a network of 24 - 32 active Medium Earth Orbit satellites to determine ground position and velocity (location, speed, and direction). On earth, the GPS navigation devices then calculate reliable location and time information in all weather and at all times when there is a clear line of sight to four or more GPS satellites.
There are many manufacturers of GPS Navigation devices and accessories including: Garmin, TomTom, Magellan, Bracketron, Lowrance, Sony, Humminbird, Jensen, Motorola, Pharos, Escort, Gilsson, Uniden, Nikon, Teletype and more.
