Surely you know what a GPS is and, suddenly, you have even used it. But this system has a functioning that is worth knowing. Behind it is a huge job preparing satellites and complex electronics. Also, there are some data that, perhaps, you do not know. Do you want to discover them? We present below the best curiosities about GPS.
