GLONASS GPS "Galileo " Comparison of three systems

"Galileo" system and the GPS system, the main difference is: "Galileo" system determines the location or near the ground than the spatial location of GPS accuracy to 10 times. The horizontal positioning accuracy of better than 10 meters, precision time signal 1 00 nanoseconds. When necessary, free use of the signal accuracy of up to 6 meters, such as cooperation with the GPS can accurately even to 4 meters. An electronic engineer illustrates this difference: "Today's GPS can only find the street, while the 'Galileo' system is able to find the garage door."
