GPS In A Nutshell
The GPS unit sitting on your dashboard owes its existence to the need for the United States military to be able to navigate the surface of the Earth with ease. In the 1970's and 1980's, the United States launched satellites into the Earth's atmosphere into geo-synchronous orbit. These satellites made it possible for the military to maneuver on land and sea with ease.
The way GPS works is simple. The GPS units receive a signalfrom the satellites in orbit. The signal is analyzed by the satellite and ground based equipment and the exact location of the GPS unit is then revealed.
Since GPS has been commercialized, the most common GPS units being used today are the car GPS units. These devices allow you to map out your route to your destination from your present location. Simply put in the address or place of interest (such as U.S. Capitol or the White House) and the device will perform all of the calculations for the correct course. The route is then displayed on the screen on the GPS so you can follow along. The best part about using a GPS over traditional maps is that if you miss your turn for any reason, the GPS will recalculate the current position and the new, best route to your destination. In advanced models, the turns and directions are not only graphically displayed but a voice command is also utilized in order to keep your eyes on the road.
Manufacturers have taken the last two decades to produce ever smaller GPS devices so their use can become more widespread. Technology has improved so much that the GPS receivers can be inserted into articles of clothing as well as other common conumer items such as cellphones, watches and shoes.
Because GPS has become smaller and the receivers and satellites are in constant contact, GPS tracking services have sprung up in recent years. These services give parents peace of mind by allowing them to know where their child is at all times. All the parent needs to do is place the GPS on the child and then monitor their child's whereabouts on the service's website.
Wonder why almsot every car is equipped with an in-dash or on-dash GPS system? It is because the GPS units are becoming less expensive at the same time their use is more desired by the population. The result is that more people recognize the value and peace of mind that these devices can bring to their lives.
For car GPS, you can go one of two ways when buying a new car. If it is an option to get the GPS system built in this is most desirable. The other option is to buy a car GPS unit and place it on your dashboard and reove it each time you leave your car. Either way you go, you will be happy you added GPS to your life. - 21392
