If you’re reading this then there’s a good chance you’re already interested in investing in a GPS Tracker. There is so much to talk about when considering the effectiveness of these devices in theft prevention but today I want to focus on how they actually work.
Surprisingly GPS Trackers utilize fairly simple technology. The GPS stands for Global Positioning Satelite. This refers to the network of satellites that the device communicates to infer current location. There are 32 of these satellites currently in orbit. Enough to ensure that over 90% of the globe is covered. A device can send a signal to one of these satellites and from this signal, an incredibly accurate record of current location can be derived. Current GPS satellites have a global accuracy of under 3 meters.
GPS technology as we know it today is the 1995 brain child of the United States Military. Originally only sanctioned for covert operations. It eventually became clear that it could have an incredible benefit to society and was subsequently made public. There was a lot of debate over whether to make this system public. It wasn’t until the infamous shooting down of Korean Air Flight 007. That President Regan finally gave in and allowed for the use of GPS systems in aircraft. It is actually quite interesting to consider the fact that a system so heavily depended on is still owned by a single entity. Although recently Britan and India have been working on their own versions of GPS that has the potential to offer far higher accuracy.
Although it is difficult to truly understand how impressive our GPS systems are without first looking into their history. GPS has an incredible history stretching all the way back to the 1950’s. In which the US navy observed a fluctuation in frequency in passing radio waves and decided to attempt to manipulate these frequencies to deduce relative location. The first attempts at GPS were incredibly rudimentary and more of a proof of concept than a full blown tracking system. Use was incredibly restricted and the system as a whole was nothing compared to today. As the public was granted more access to the technology the dependency on it increased and innovation was needed in order to equip the system with the capability to cater for its new found responsibilities. This is where the 32 satellite strong system we know today was introduced.
As GPS technology continues to improve. We will see an increased capacity for Trackers to locate to a more precise amount. We are already beginning to see an incredible amount of accuracy and combined with a pairing with GSM technology it is actually quite incredible the results we now see.
