The Global Positioning System was first conceived as a series of geo-synchronous satellites which would provide navigational signals for military ships at sea. This task was soon expanded to include vehicles on land, and then further expanded to include corporate and eventually individual use. Now there is a series of satellites, all relaying the pertinent information to everything from aircraft carriers on maneuver to container ships carrying goods from one continent to the other to soccer moms trying to find the best way to get the kids from school to the practice field.
GPS receivers are not just for vehicles any more.
CarKart carries a large variety of devices which are perfect for cyclists, hikers, and runners. These range from simple turn by turn devices to handhelds which provide topographical information for mountain climbers. There are devices which runners can wear on their wrists like a watch. These provide not only directional data, but also keep track of distance covered, elapsed time, and can calculate the wearer’s average speed. Some even monitor and record the wearer’s vitals.
For those who own a fleet of vehicles, be they luxury cars or delivery vans, there are signal boosters which can pinpoint the location of the vehicle down to inches.
