It is commonly known that satellite tracking is the method that GPS uses in order to provide the location of a vehicle or a person at any given point in time. With a total of 24 satellites in operation at the moment while three satellites are in place as a part of failsafe measures, one can only imagine the accuracy of information that can be provided by these satellites at any given point of time.

Whether one requires GPS vehicle tracking or being able to track packages that are lost or stolen, it should be heartening to know that almost anything under the view of the sky can be tracked provided there is a GPS receiver attached to the vehicle or the package.
Another area where GPS is so useful is the area of commercial transportation which is also known as GPS fleet tracking, which can not only track one vehicle at any given point of time but provide with information on a group of vehicles that are on the road to deliver materials.

When one want to track the position of a vehicle, the GPS antenna collect the signals from the satellites at any given point, and then feeds it to the unit to process it in terms of time and speeds after which this data is sent to systems control to validate that schedules are being kept and if not, adequate reasons and alternate routes are also provided.
