Global Positioning Systems (GPS) have been universally available on the market for well over a decade now and are more common than ever in every day objects. GPS tracking is found within cars and mobile phones; you can purchase GPS watches, pens or a dongle for your laptop. Tracking a person or parcel has never been easier.
But how does a GPS tracker really work?
Signals are transmitted for satellite networks that orbit the earth. These are used to ascertain GPS tracker locations. GPS receivers come in three different forms. There are receivers that store positional information, receivers that relay their own positions, called data pushers, and receivers that enable their users to request positioning data through the use of an SMS text message. These are known as data pullers.
GPS trackers that come off of the shelf are able to provide information that is considerable accurate up to 10 metres and are sufficient for most normal usage. These com in two different formats. The first of these, data pullers, provide real time updates of the position of the tracker through a computer that is linked into mapping software. Google Earth is an example of this mapping software. GPS trackers of the data pushing variety are employed for the purpose of tracking and following goods that have been stolen or for the live progress of vehicle, as with emergency service transportation. With these the device transmits a signal so that the user is able to visualise the position of the GPS tracers.
With the second type of system, data pullers, the individual is required to request the location of the device. This is typically accomplished by sending a text message to the device, to which the tracker can reply via a response text message that provides the mapping co-ordinates for the current location. These can then be traced through a mapping application, GPRS mobile phone or fed into a compute. Businesses that possess fleet vehicles frequently need to know the availability and to the progress and thus, they employ this technology to make certain that taxis, ambulances and pizza delivery services are on schedule.
In instances where an exact location is not necessary, but where journey details or the route that is taken must be known, a GPS logger will suffice. These devices log the details of direct, speed and position and store them to a memory chip where the can be recovered at a later time. These units are lightweight and small and transport with east. These are popular with cyclists and other sports enthusiasts who use them to analyse their sports performances at later dates. These devices enable them to increase the performance and driving style or to alter the selection of routes.
