There are many ways to find your position on Earth. Some are more accurate, some are less accurate. The easiest way to find your location is by using the global navigation satellite system or GNSS. You can use your smartphone, handheld GPS unit or GNSS receiver to do that. But how do these gadgets find a particular point where you stand at the moment?
