Why You Should Invest in GPS Vehicle Tracking

By Salvador Paez

What is the main difference between GPS and other vehicle tracking systems that make it so popular a choice for many civilians?

Simply put, GPS has the most advanced satellite system technology in the whole world. Aside from that, it is the world's only Global National Satellite System (GNSS) that is fully operational. The GPS system is also wholly being maintained and regulated by the government, making its navigational services completely cost-effective for the regular civilian and motorist. All these make the GPS system one of the best and most attractive means for vehicle tracking.

Most vehicle tracking systems utilize some other communication protocols between the transmitter and the remote controller, protocols such as radio frequencies or GPRS. Examples of a radio-frequency-type protocol system are the LoJack and the LORAN vehicle tracking systems. The GPS, on the other hand, utilizes satellite frequencies in the form of microwave signals, transmitted by at least 24 medium Earth orbit satellites that allows the remote controller to determine the precise location, direction and speed of the transmitter. All this is use of sophisticated technology is free-of-charge, which should explain the popularity of the GPS among navigational systems that are used at a civilian level.

It should be noted that although the GPS is a satellite-based navigational system, direct line of sight with the sky is not necessary in maintaining a strong signal. Even vehicles that are traveling through tunnels are still easily defined by the GPS.

Vehicle tracking is not the only purpose of the GPS satellite system at a civilian level. There are many other uses of the GPS, including navigational gears used in hiking or outdoor camping activities. Other applications often deal with environmental activities such as determining atmospheric conditions as well as analyzing varying levels of gravity across different parts of the planet's surface.
