GPS Systems - How They Work
They have become the must-have automotive accessory of the 2000s. Helping motorists get to their destinations without the need for a bulky map and even guiding them past traffic snarls with ease, GPS systems are now almost as indispensible as car radios. But just how do these devices work and what makes them so valuable are questions that make those who have not taken the plunge wonder if they are worth the price of admission.
The very most basic function of a GPS system is to be able to pinpoint a persons exact location, and to help direct a motorist to another location that the GPS has marked for them. What many people are not aware of is that a GPS is actually a receiver and not an actual system. What you should know is that GPS systems are in reality a set of around two dozen satellites that were installed by the military into orbit. All of these well placed satellites will orbit around the earth two times each and every day. If you happen to own a GPS receiver, you will be able to have contact with a minimum of four of these satellites -- which means you will have no problems in determining your exact location.
GPS systems can operate accurately in a number of conditions, but they are not infallible. For example, GPS is accurate regardless of weather conditions or the time of day. The signals, however, can be blocked by thick forests, canyon walls, large buildings and other similar obstacles. On average, GPS systems are accurate within 15 meters, but some newer machines have a margin of error that is even less.
GPS signals are technically free to receive, but it is through paid services that motorists get the information they need the most to navigate travel. Thanks to the computerized backing services provide, GPS receivers can do more than pinpoint global position using the system of longitude, latitude and height. Extras that can come along with a GPS receiver device and a paid service include:
Road map functioning " A GPS receiver can be used in conjunction with downloadable road maps to walk a motorist through a trip. Some devices will even determine the best route to take a driver from Point A to Point B and give turn-by-turn verbal directions along the way.
You are going to be able to get traffic updates in real time, so that you can avoid any particular traffic jams that would keep you from getting to your destination in a timely manner. This way you will be able to avoid things like construction and traffic accidents.
Trip planning " When the GPS system is backed by a computerized service, motorists can receive invaluable information for trip planning. Not only will a GPS system in a car determine the best route for a motorist to take, but it can also calculate travel time, distance and other important factors.
Landmark location " GPS services that provide maps and directions also sometimes offer landmark location in relation to a persons position on the globe. Landmark information can be requested for such things as points of interest, restaurants, hotels and more.
When you go ahead and supercharge your GPS, you are really going to be able to travel with ease. - 21396
