Real time tracking is one of the best ways to keep your vehicle protected from thieves and criminals. Tracking vehicles in real time works by sending information from the transmitter to the receiver every second. This allows you to monitor where your vehicle is any time you want, without the unnecessary lag.

The GPS satellite system is the most commonly used type of protocol system for real time vehicle tracking. It uses 24 medium Earth orbit satellites that continuously scan different areas of the planet's surface, and transmits the data collected to the receiver in the form of microwave signals.

The GPS system is often mistaken to require a clear line of sight so the satellites can transmit the accurate location, speed and direction of an object. However, the artificial satellites can still provide a very useful reading even if the line of sight of the GPS is obstructed. This makes the GPS an excellent navigational tool because it can still track your location even during the most extreme conditions, such as being inside a tunnel, cave or jungle.

Another advantage of the GPS among other navigational systems such as those that utilize radio frequencies and etc. is that the GPS satellite system is being maintained by the government. This is good for two reasons: one, the technology behind the GPS is almost always up-to-date and two, it comes as almost free-of-charge to civilians.

GPS vehicle tracking system providers often provide their clients with different options regarding the quality of vehicle tracking services they wish to subscribe to. For example, one client may wish to avail of a service wherein the server refreshes its data every after 10 seconds. On the other hand, another client may wish to subscribe to a real time vehicle tracking service, where the server refreshes in real time with the vehicle being tracked. Of course the latter service comes at a greater fee, but the quality as well as precision of service is far superior over the former option.
