How Does Bluetooth GPS Work?

A Bluetooth GPS navigator is one of the best tools to come out in a long time. Bluetooth GPS works with many different devices so that you will never be lost again. The Bluetooth GPS ties into a satellite system to triangulate and coordinate your position. This system has been in place for a while and when coupled with Bluetooth it makes GPS extremely portable and easily connectable.

History of Bluetooth GPS and How it Works for You

After the crash of Korean Air Lines Flight 007 in nineteen eighty three, President Reagan started an initiative to make GPS available for free for civilian use. Since that day GPS has expanded and now covers the entire globe. Its technology helps in monitoring earthquakes, synchronization of telecommunications networks, map making, navigation worldwide, and an assorted list of other uses. Primarily however Bluetooth GPS will be used for on road navigation and tail hiking to find you position. The question really is not what it is used for but rather how Bluetooth GPS works.

The concept is fairly simple. The Bluetooth GPS receiver calculates its position based on the signals it receives from satellites. Each satellite continually sends messages that have the current time, the parameters to calculate the location for the satellite, and the general health of the system. These signals travel down to the receiver and it uses the arrival time of each message to measure the distance to the satellite and from that it can determine the position of the receiver using geometry and trigonometry. The Bluetooth GPS then converts these coordinates to latitude and longitude which can then be displayed on a map.

It would seem that three satellites should be sufficient for the Bluetooth GPS to accurately predict the position, but in fact that is not the case. The Bluetooth GPS needs four satellites to accurately account for time in addition to its location in space. By adding this fourth satellite the measurements taken can be less accurate and can be more easily calculated.

Well there you have it, the basics as to how your Bluetooth GPS system works. While the system contains many components that are far more complicated than what has been outlined, hopefully this gives you a good idea of what happens in order to calculate your position. This system works on some very simple concepts but requires sophisticated equipment to execute. Your GPS unit is a marvel of technology, and hopefully you can appreciate this a bit more.
