The GPS works by calculating the distance of an object from the three aerials that are nearest to it. This means the object must be taking out a signal of some sought on order for it to be traceable. In this case it would have to be a GPS signal. There are many devices that use this technology including cars and cell phones. If the person you’re looking for is using any device that emits this kind of signal then it is possible to locate that person using the Global Positioning System.

If the person you’re looking for has a phone then the person’s phone should have GSM or Global Positioning System on it. The software ca be installed on those that don’t have this technology. You can locate a person with a Global Positioning System if they are also using such a phone.

The accuracy of this system will differ depending on the country from which you are tracking from. In the UK the marginal error is 10m, in USA, Canada and South America the error is 25m and anywhere else in the world is that error is not more than 50m. If someone has a phone that has the GPS technology but operating in a country that does not have GSM networks you will not be able to trace them.
