An anonymous reader writes "The Global Positioning System (GPS) is a satellite-based navigation satellite system consisting of a network of satellites which provide positioning, navigation, and timing services in all weather, anywhere on or near the Earth.
Use of space-borne positioning and timing data is now commonplace, in everything from freight movement to synchronisation of computer networks. Cellular and data networks, shipping and air transport, financial systems, railways, agriculture, and the emergency services all make frequent use of GPS. There are also many different recreational uses of GPS. The one that first springs to mind is for tracking in motor vehicles. GPS helps drivers find the best route to a specified location, summon help in the event of an emergency, plot the location of the vehicle on a map, or find the nearest bank.
This article focuses in selecting the best free software for undertaking a wide variety of GPS related tasks. Hopefully, there will be something of interest here for anyone who needs to keep track of where he or she is, to find the way to a specified location, or determine what direction and how fast they are going."
