Now, with distance measurements from a few more sa tellites, the receiver can determine the use! rs impersonate and display it on an electronic map. The accuracy of a set determined with GPS depends on the sign of receiver. Most hand-held GPS units grow about 10-20 meter accuracy. You can appreciate the value of the GPS engineering by taking a look at the numerous advantages of a GPS thingamajig.
