I’m am sure that by now, nearly everyone on the planet has heard of the Global Positioning System or GPS. But how many people really know how they work? This is a brief summary of how the GPS works.

The Satellites

GPS systems have a network of more than 50 satellites that cover the globe and enable the GPS system to work. In order to locate the position of a GPS signal, at least three satellites have to be able to receive the signal that is being transmitted. Then these satellites compare notes so to speak, and from there they triangulate the desired position.

Most people don’t normally associate golf with GPS technology, but due to the recent wave of technological advancements, it’s is finally here, and the latest golf GPS devices are riding this wave.

It is all about knowing where you are; in the game golf this translates into discovering where you are, where your ball is, and where do you want your ball to go. Golf GPS devices are handheld and they are used as a guide for distance and yardage to the hole, more than anything else.

Even though today’s GPS technology doesn’t require a great deal of space, the software that allows the device to function does. Once software, is created, it gets improved upon and will get smaller. All of the functions that come with the GPS device aren’t needed by every consumer.

A GPS unit really only requires a radio emitter and a clock to work. The emitter sends the time reading of the clock to a overhead satellite. Then the satellite calculates the amount of time that it took for the radio signal to reach it, and then the satellite calculates the distance from this information. Three or four satellites will compare their locations with the amount of time that it took the signal to reach them. This is how they are able to determine your location.
