Passive GPS trackers store the GPS information on the tracker until the truck returns to a central location or office. When the truck is within range of a wireless base station, usually under 500 yards, the GPS tracker will transfer the GPS tracking data. The GPS data is then put in a ...
To synchronize the clocks in orbit with those on the earth and thus compensate for the timing error, GPS must make a fourth satellite measurement.EBSCO_bspScientific American
What is GPS? The GPS is a satellite-based navigation system that can precisely tell you where you are. Satellites that orbit the earth are continuously sending signals back to earth. Once the receiver gets these signals from 4 or more satellites—it can figure out where you are or what ...
