Garmin was founded by Gary Burrell and Min Kao and hence the name "Garmin". Garmin is actually a parent company of a group of companies founded in 1989. The company develops consumer, aviation, and marine technologies for the Global Positioning System.

The main and most famous product of the Garmin company is the GPS system or the global positioning system. It is a satellite based navigation system now available for civilian use. The best thing about GPS is that there are no subscription fees or setup charges for using GPS and it works in any weather condition and all around the world!

Today's GPS receivers are extremely accurate! What affects the accuracy of the GPS is certain atmospheric factors and other sorts of errors like the delay caused by the layers of atmosphere as the signal passes through. A receiver's in-built clock is not as accurate as the satellite ones and so there might be slight timing errors.

GPS satellites transmit two low power radio signals. The signals will pass htrough clouds, glass and plastic but will not go through buildings or mountains. The signal contains contains important information about the status of the satellite , current date and time which is essential for determining a position.

At first civilians were not allowed to use GPS system. But ever since it was made available for us it became a very necessity! Today, almost literally, I can not locate my bathroom without one. The GPS answers questions like where am I? Where am I going? Where are you? What's the best way to get there? When will I get there?

It is the only system today that can show you your exact position no matter where you are! You will have a receiver which you can hold in your hand or mount in your car. GPS is also a big help for blind people who no longer need a dog as their guide. The person should just enter the address and a special program calculates the best way how to get there, using a digital map. You can use the system to protect your car from robbery as well. Now either the robber tries to gain control of the car which is registered by a computer inside of the car or you can report your car as stolen by calling a control center. In both ways the center can locate the car using the GPS system signals.

So a GPS can be used to do a lot of things in our everyday life. It is becoming an everyday tool like a mobile phone nowadays. Whether you are lost or someone else is - it is never too hard to find out where you are using this device. It is useful in so many ways more than one! I find it to be a necessity and once you start using it so will you. It calculates and shows me the easiest and shortest way to reach some place which is extremely useful especially when I do not have much time. It saves me money and time!
