GPS, or global positioning system, is a tool that is used to measure distance and to help pinpoint location any place in the world. The fact is that it is an excellent tool that can do so much more than just tell you where you are. And, it is being used in everything from heart rate monitors to automobiles. If you haven

Global Positioning System is a navigational aid, funded and controlled by the U.S.
Department of Defense. Since GPS systems utilize 24 satellites that orbit the earth
in a grid pattern, there are always six to eight satellites that are able to
communicate with any given position on earth at any given time. What this does is
give the average consumer the power to find any place on earth at any time day or
night. Just think of the benefits this provides for a wide variety of the public.
Some of the benefits we might receive from GPS are:
Fuel economy: If you want to maximize your fuel economy you’ll need a good
GPS system. Saving money at the pump as well as wear and tear on your vehicle
should be one of the main reasons why you would want a good GPS system in your
vehicle. Accurate driving directions not only will save you time in your daily
travels, but also will save you substantial gas money when travelling from place
to place. This is especially important for delivery and courier services.
Travel directions: Utilizing a GPS system will give you accurate directions
for travel. Weather you are travelling locally, across country, or globally, you will
get accurate direction and constant monitoring of your current position. I wouldn’t
think of taking another family vacation without a GPS system in my vehicle.
Recreation: Weather you are camping, or hiking, a hand held GPS unit will
benefit you. I can’t imagine going camping in the middle of the woods and not
being able to find my way out. The news is filled with daily reports of people
(or kids) that go hiking in the woods or the desert, and can’t find their way back
home or to their campsite. A GPS unit is the answer for these people.
Maritime: If you have ever watched one of the popular fishing shows on T.V.,
or are a fisherman or sailor yourself, then you know how a GPS unit will benefit you.
Getting lost at sea or on a large lake would not be fun. The other side of the coin
is the fisherman, say there is a great hotspot on any given lake in the world, that
specific spot can be saved in your GPS system and found again at any time. This
could be beneficial to the recreational or professional fisherman.
Tracking: If you run a courier business, rental business, or just plain delivery
service, and need to keep track of several vehicles, then GPS is what you need. Keeping
track of your vehicles will keep your overhead down. The other end of tracking is keeping
track of a family member or child, a GPS tracking system will aid in your efforts.
I have over 25 years of automotive repair experience. I know quite alot about everything that
has to do with your auto. I am ASE certified as well as GM certified. I am originally from
Wisconsin, born and raised, lived there for 38 years. I’ve spent many years in the summer-humid
/winter-icy/snowy climate and have dealt with not only repair conditions there but also how to
drive properly in those conditions. Fuel economy is probably the most important element to saving
money today, and how you drive or how your vehicle performs plays a big part in that. I now have
lived in Phoenix for the past 6 years, in the middle of the desert where it reaches up to 115
degrees on a summer day. I’ve seen it all as far as vehicle maintenance and care goes and can
help with any problem by email or by visiting my website at http://www.your-auto-repair-help.com/gps.html

Our ancestors used to work extremely hard to protect themselves from getting lost in this mysterious world. They used to erect monumental landmarks, study conventional land maps and of course they used to mark the stars in the night sky.
But today it is very easy to know one’s position. You just only have to get a pocket-sized gadget that will make you know your exact position on this earth at any given moment. The system of knowing one’s exact position on this earth is known as ‘Global Positioning System’. If anyone has a Global Positioning System (GPS) receiver, and if the sky remains clear, then no way can he get lost on this earth.
Of note is that this pocket-sized gadget, the Global Positioning System receiver, is quite expensive and it also involves a fair amount of technical ingenuity.
GPS is specially a Satellite Navigation System that helps in tracking our exact location with the help of satellites. The Global Positioning System is mainly funded and controlled by the U.S Department of Defense (DOD). The system was primarily designed for the operation of U. S. military. But there are also many civil users of GPS across the globe. The Global Positioning System provides some special satellite signals which are then processed in the GPS receiver. These GPS receiver’s not only track the exact location, but can also compute velocity and time.
The positions can even be computed in three dimensional views with the help of four GPS satellite signals. The Space Segment of the Global Positioning System consists of the GPS satellites. These satellites send radio signals from space which are received by the GPS receiver.
There are more than 24 operational and 3 extras (in case one fails) GPS satellites that moves round the Earth every 12 hours.
The control of the Global Positioning System consists of different tracking stations that are located across the world. These monitoring stations help in tracking signals from those Space Vehicles which are continuously orbiting the earth. The Space Vehicles transmit microwave carrier signals. The users of the Global Positioning System have GPS receivers that convert the satellite signals which estimate position, velocity and time. Four satellites are required to track the three dimensional location and time. The primary function of Global Positioning System is the navigation in three dimensions. The Navigation receivers are used for aircraft, ships, and ground vehicles and sometimes for personal use as well.
With GPS receivers, precise positioning of any location can be done. The Global Positioning system is based on a simple mathematical calculation that operates through a process called Trilateration. In order to make the simple mathematical calculation the GPS receiver should know two things.
++ One is the location of the place to be traced by at least three satellites.
++ Secondly, is the distance between the where the receiver is located and each of those Space Vehicles.
All units have multiple receivers, and can pick up signals from several GPS satellites at a same time. These radio waves are electromagnetic energy that travels at the speed of light.
The civil users across the world are allowed to use the Standard Positioning Service without any kind of charge or restrictions.
