You will never need to ask for directions again after purchasing a new GPS system. A GPS can be used
when boating, traveling, camping, and hiking.
A GLOBAL POSITIONING SYSTEM (GPS) permits land, sea, and airborne users to determine their position, velocity, and time 24 hours a day, in all weather, anywhere in the world with a precision and accuracy far better than other radio navigation systems.
The GPS concept of operation is based upon satellite ranging. Users figure their position on the earth by measuring their distance from the group of satellites in space. The satellites act as precise reference points.
Each GPS satellite transmits an accurate position and time signal. The user's receiver measures the time delay for the signal to reach the receiver, which is the direct measure of the apparent range to the satellite. Measurements collected simultaneously from four satellites are processed to solve for the three dimensions of position, velocity and time. This GPS explanation comes from the US Coast Guard Web site, a link to their site is listed below.
