GPS standing for Global Positioning System is a network of satellites, first developed in 1970s by the USA. It was developed as a part of the nation's defense program which was later opened to the civilians for use during the time of President Bill Clinton. With 24 satellites in action, there are other 3 stand-by satellites extra. These satellites through a GPS real time tracker allow people to track vehicles and assets and provide helpful information about their exact location in terms of longitude, latitude and altitude. With more advanced technologies getting invented every day, especially in the gadgetry field, online tracking software are now widely used across the globe. With the help of a GPS real time tracker, you will be able to obtain current and detailed information about the object that has been tracked and the whole process is done via wireless networks. The reason why it is called real time tracking is because the information delivered are current, unlike in Passive systems where information procured can be checked after the real time of their occurrence. A catch about this intricate technology is that it works more or less in the same way as cellular phones work. The only difference that remains is that the satellites of a GPS real time tracker are different from the communication ones. A GPS real time tracker is too small to locate and can be easily installed on vehicles and objects that can then be monitored besides controlling its features. The GPS locator devices used earlier were equipped with separate antennas and modems as receptors for collecting the GPS data. But, the more recent versions are designed to be more self contained and hence, smaller in size. The online tracking software can both gather and transmit GPS data through wireless networks such as, Analog, Mobitex or GPRS that can be viewed by the user over the Internet. You can update the data every five minutes. There are a large number of such software available over the Internet. One of the most effective online tracking software is Unpack&Track that offers an easy solution to tracking assets and vehicles. The trackers on the objects create a Geo Fence around the object that behaves like a protection boundary for the target. Once, the object is shifted outside the boundary, the device immediately transmits signals to the user informing them about the whereabouts of the object, henceforth. These GPS data are immensely helpful in tracking down the object. Moreover, being in real time, the signals transmitted are just immediate and live. These devices are widely available at moderate prices at online retail stores.
