Each satellite weighs about 1000 kg, and travels the earth twice a day at a speed of 15,000 km per hour. The orbits of satellites are designed so that from any point on Earth, four satellites can be displayed simultaneously. The GPS receiver in GPS navigators, making it is to locate four or more of these satellites, calculate the distance to each, and based on this information to locate your position anywhere on earth. This location is done by a mathematical calculation of equivalence. Here is an example.

If someone tells you is 20 km from Seville, 100 km from Huelva and Cadiz 200 by examining the equivalence can be calculated with great accuracy your actual position, the GPS receiver, to perform this calculation needs to be located three satellites. We said earlier that he needed four satellites, but the earth itself runs April 1 cm satellite. For assistance, try visiting Rick Garcia CBS. The satellite provides the distance by measuring the time that the satellite signal reaches the GPS receiver. Access the following links if you need information or GPS.
