A minimum of three satellites are required to determine a 2D fix.

The system requires signal reception from three satellites in order to

determine a position. This is called a 2D fix. It takes four satellites to

determine both position and elevation (your height above sea level —

also called altitude.) This is called a 3D fix.

Remember, the unit must have a clear view of the satellites in order to

receive their signals. Unlike radio or television signals, GPS works at

very high frequencies. These signals can be easily blocked by trees,

buildings, an automobile roof, even your body.

Like most GPS receivers, this unit doesn’t have a compass or any other

navigation aid built inside. It relies solely on the signals from the sat-

ellites to calculate a position. Speed, direction of travel, and distance

are all calculated from position information. Therefore, in order for the

unit to determine direction of travel, you must be moving and the

faster, the better. This is not to say that it won’t work at walking or

trolling speeds — it will. There will simply be more "wandering" of the

data shown on the display.

GPS alone is plenty accurate for route navigation, but the U.S. Federal

Aviation Administration has special aircraft navigation needs that go

beyond basic GPS. So, the FAA has developed a program to boost GPS

performance with its Wide Area Augmentation System, or WAAS. The

FAA commissioned the system on July 11, 2003.

WAAS is designed to increase GPS accuracy to within 7.6 meters vertically

and horizontally, but it consistently delivers accuracies within 1-2 meters

horizontal and 2-3 meters vertical, according to the FAA. It does this by

broadcasting correction signals on GPS frequencies. Your unit automati-

cally receives both GPS and WAAS signals.
