Global Positioning System

Global Positioning System (GPS) is the only satellite navigation system that works properly. This system uses 24 satellites that send signals to Earth Microwave. This signal is received by the recipient of the tool on the surface, and is used to determine position, speed, direction, and time. A system similar to the GPS anatara other Russian GLONASS, Galileo the European Union, India IRNSS.

This system was developed by the Department of Defense the United States, with the full name is NAVSTAR GPS (common mistake is that the NAVSTAR is an acronym, this is wrong, NAVSTAR is the name given by John Walsh, an important policy determination in the GPS).

Vehicle tracking system
Other uses GPS tracking is as vehicles, with car owners bamtuan GPS / fleet managers can know where there is only kendaraannya / asset movement is at this time.

The earthquake
Even at this time, the GPS with high accuracy can be used to monitor the movement of land, the only ordenya mm per year. Monitoring the movement of land is useful to estimate the occurrence of the earthquake, the movement vulkanik or tektonik
