GPS

GPS-stands for Global Positioning System and is a system that determines your position by receiving signals from 24 Satellites. Knowing exactly where you are is the first step towards not getting lost. GPS-trackers supplied by Chinese manufacturers with the most competitive prices and superb quality.

When people talk about "a GPS," they usually mean a GPS receiver . The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). The U.S. military developed and implemented this satellite network as a military navigation system, but soon opened it up to everybody else.

A GPS receiver's job is to locate four or more of these satellites, figure out the distance to each, and use this information to deduce its own location. This operation is based on a simple mathematical principle called trilateration . Trilateration in three-dimensional space can be a little tricky, so we'll start with an explanation of simple two-dimensional trilateration

If you are going camping or fishing in an area that you have not been in before:

1. Let someone, know where you are going and about what time you will be back.

2. Take a GPS unit with you.

3. If you don't have a GPS and you have phone service in the area you will be going you will have that too, if you get turned around. Someone said you can't get lost, even with a GPS, hasn't been in the woods.
