GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers can calculate exactly where the user is by taking this information and using triangulation. The time difference tells the GPS receiver how far away the satellite is. A GPS receiver can calculate the latitude and longitude and track movement if it is locked on to the signal of at least three satellites.
The most basic of GPS systems will provide you with a route from one waypoint to another waypoint or to multiple waypoints, depending on your destination and trip plan. Any route you plan in a GPS system is completely reversible thanks to the innovative design of such systems.
