First of all, for all those who still don’t know what GPS stand for here is an explanation. GPS is shirt from Global Positioning System, which is another name for a satellite navigation system, which we usually use in our cars. A GPS device can help us in many situations when we don’t know the road, when we get lost, etc.
GPS tracking devices are very useful items which can help us determine where certain person or car is situated. In order to be able to discover these details, the actual car or person has to be equipped with a GPS tracking device.
How one GPS tracking device works is very simple. Actually, these items are measuring the distance of the object from each of the sensors (GPS satellites) and calculating its current position based on the location of the sensors.
While the GPS tracking device is locating the object, it is at the same time recording the tracking signals. These recordings can be even transmitted over the internet to a cell phone or a computer at your home, where you can easily save all the recorded information. This means that GPS tracking devices can view and show information in real time, although this is not the case with all GPS tracker models.
There are actually three models of these units. There are data loggers, data pushers and data pullers. They all have different techniques of data logging and data retrieval.
Data loggers are retrieving the position of the tracked object at regular intervals. These GPS tracking devices are able to store all the information on their flash memory which can be transferred to other sources, such as computer, with a help if a simple USB connection.
Data pushers are usually used for security reasons as they are sending the recorder data directly to other sources, such as computer, at regular intervals. Thanks to these GPS tracking devices you can easily monitor any kind of vehicles as they can be located instantly. This is as well a great security system for theft prevention. Also, data pushers are often used for spying.
Data pullers are not used very often, and are the least popular method from the three mentioned ones. However, these GPS tracking devices can find their purpose for tracing stolen goods. Data pullers are used only in cases when the tracking is not required to be done very often.
