GPS satellite MAP navigation operate simultaneously to form a constellation that orbits around the Earth every 12 hours. Ground stations can track each satellite's location. GPS satellite MAP navigation synchronize with each other so they can repeat the signals and transmit them at the same time. Transmitted signals arrive at the GPS receiver at slightly different times because some satellites are farther from Earth than others. To calculate the distance of the GPS satellites, you must determine how long it takes the signals to reach the receiver. The GPS satellite MAP navigation receiver estimates the distance to at least four GPS satellites by calculating their positions in three dimensions.
A GPS satellite MAP navigation system in your car--with the help of global positioning satellites (GPS) sending out synchronized signals to wandering souls all over the planet--pinpoints your location with great accuracy. When your position is compared with the GPS satellite MAP navigation system's embedded maps, frustrating voyages of all kinds turn into precision-guided tours.
