A GPS receiver receives satellite signals and pinpoints your current position. By entering coordinates of a geocache, a GPS receiver will typically display an arrow giving you the distance and bearing of the geocache.
Modern GPS receivers operate on twelve channels, meaning they can pick up the signal from up to 12 of the 24 satellites in the GPS constellation. Older units operate on only 8 channels. While these older units are still able to be used for geocaching, thay are not as accurate.
