How GPS Works
Since Man first fashioned tools to help him hunt, he has always tried to improve the technology that assists him in living on this sometimes unforgiving planet. Over the centuries these tools have developed and become more efficient and effective and progressively have become more and more high tech. GPS, or Global Positioning System, is one of these advances in technology.
It seems every other person has a GPS device of some sort. And why not? GPS tracking devices allow people to keep track of their loved ones and their vehicles and allow them to keep from getting lost on their out of town trips. While it is nice to admire GPS for the technological marvel it is, one should be informed of what GPS is and how it works.
The way GPS works is a relatively simple concept when broken down completely. Strategically placed satellites that are orbiting the Earth, relay a signal searching for any GPS receiver on the surface of the Earth. The signal is received by the GPS unit and then decoded. The unit and the satellite then communicate with each other and the satellite then transmits the coordinates to the GPS unit. This transfer of data allows anyone looking at the GPS screen to see where they are currently located.
During the 1970's and 1980's the satellites for GPS were deployed for the United States military to use in navigation for their units on land and at sea. It wasn't until the '90s that GPS was allowed to be used for commercial use. Since that time, GPS has rapidly wormed its way into the marketplace and into our lives. It is so widespread and commonly used that a good unit can be found inexpensively.
Since the price is inexpensive, this means that GPS is affordable for pretty much every socio-economic class of people. Given the availability and low cost, GPS units are pretty much found in every vehicle on the road. This is to be expected because these units help you keep from getting lost and save you peace of mind.
If you purchase a car and it has a GPS option, you are well served to purchase it as it will not only help you, it will increase the vehicles resale. If your vehicle did not come equipped with a GPS as an option, you will want to find one that fits your budget and individual preferences.
The last thirty years, GPS has gone from military hardware to an item on our dashboards that we cannot live without. What a journey, huh? - 21393
