GPS Navigation everywhere

In our China, more and more families have car, as a result of the demands of GPS navigation is becoming larger.

First, let me tell you some information about GPS navigation. If Navigation stands for "determining of position and direction on or near the surface of the Earth", than GPS Navigation stands for the same with the help of the Global Positioning System (GPS). A GPS chip is a small radio-receiver that can capture the signals of several GPS satellites simultaneously. This way it can compute its Position, Velocity and the exact Time. This information is given out in encoded form.

In the first (non-mapping) GPS receivers this information was made visible on a small LCD screen. A small computer program in the receiver translated the information about subsequent positions into dots on the screen. This way you can see where you came from and were you actual are, as well as the track that you followed to come to your actual position. As long as you move, the system can also calculate the direction in which you move, by comparing subsequent positions. If you project your direction over a longer distance, you can even see where you are heading.

This seems maybe rather abstract, but with some smart extra possibilities of the internal program and only some external buttons for the user, you can indicate waypoints or save waypoints at specific points along your track, which facilitates navigation. You can also plan ahead and create a Route, along which you want to do a future travel. It would be of great help if you were somewhat familiar with the different GPS Terms.

In normal circumstances you will use these techniques with a (topographic) map of the region where you want to travel (drive, hike, walk), but in emergency situations you can very well use it to your advantage, even if you do not have a map. At least it will prevent you from walking around in circles. The more you exercised with your particular GPS receiver, the more you will be able to get out of it.
