When most people of think of GPS tracking, they automatically think of the automotive industry. But, GPS trackers are used across several different areas including on airplanes, on ships, and even on people. The actual GPS systems themselves may vary across the different instances where they are used, but the principle is the same and here we look to uncover the ins and out of GPS tracking.

A GPS receiver works by listening for signals from four or more satellites and then records the time it takes for the signal to arrive back. When all signals are received back, the GPS receiver compares each signal's time and uses this information to estimate its distance from all four receivers. The next step is for the receiver to use trilateration to determine the objects exact location (within around 3 meters). Trilateration is the mathematical technique used by GPS tracking systems that enable the object's location to be pinpointed. It takes the points of all the signals that have been received back and plots them down. Where the signal areas overlap is where the object is located.

GPS tracking systems were first introduced to the consumer market back in 1988 with the Magellen NAV 1000. This was a handheld consumer GPS device that the company anticipated would be used for recreational purposes such as hiking and canoeing. Over 10 years later, the first commercially available GPS mobile phone was launched. In 2001, GPS technology had advanced quite a lot and private companies began producing products such as TomTom and Garmin in-car GPS tracking devices.

In the early days of vehicle tracking systems, although they were good for their time, they were nothing compared to what they are now. The first types of systems were difficult to use, expensive to buy and were largely inconvenient at the time. However, GPS tracking systems have come leaps and bounds over the past 15 years and now they are sophisticated devices that could just save you a lot of time and money. Some extra features they include nowadays include being able to produce reports on driver behaviour, the ability to monitor the vehicle's performance and gas consumption, and the ability to diagnose common vehicle faults.

There are currently 31 satellites orbiting the Earth 24 hours a days, 7 days a week, providing us constant coverage for our GPS tracking devices. GPS tracking systems not only protect your vehicle, but also provide you will a range of valuable information to enable you to get the most out of your vehicle. Having come down in price since they were first introduced, they are now an affordable solution to ease your worries and, most of all, keep your vehicle safe.
