Geocaching NSW: How GPS works

GPS in research

The GPS is used quite extensively in the commercial sector by trucking and freight corporations to monitor shipments of goods and plan routes to deliver shipments faster and more efficiently.

Some cars have GPS on-board navigation to assist drivers in finding their way through a busy city or to locate their car if it has been stolen. Similarly, the GPS units in Queensland trains provide passengers with information about where the trains are and when they will arrive.

Further, the GPS is used to assist geologists, archaeologists, environmental scientists and zoologists with survey work.

Australian taxis are also equipped with GPS units, which are linked to an emergency response system. When the driver pushes a button, the unit sends a message to dispatchers, who can contact police with the exact location of the incident.

And, even farmers are using GPS receivers, to map patterns in soil quality and determine where to use different fertilizers and herbicides.
