The GPS system is for everyone. It can be used to permanently map the location and altitude of any geographic feature or site such as a tree, a favorite fishing hole, home, camp site, workplace, or an apiary. The receiver can be used to store so-called waypoints while enroute driving or walking to or from a location. The routes created by this process can then be followed in either direction using the GPS receiver as a compass and electronic guide pointing you in the right directions. The receiver can also be used to find the shortest route between two points and calculate the time of arrival.
Some units even provide the user with real time course and speed information.
The intent of this feature is to provide greater resolution for U. S. military receivers than for receivers of adversaries. Employment of SA varies from day to day and can reduce the accuracy of civilian GPS receivers to 25 to 100 meters. Still, that's close enough to find an apiary. The GPS navigational system is very easy to use. To begin using the receiver, the operator must install a set of batteries and turn it on.
