How Does “GPS” Work?
GPS stands for “Global Positioning System”. Launched by the United States Department
of Defense, GPS consists of a constellation of 24 satellites orbiting the earth at nearly
11,000 miles. These satellites are traveling at a speed that allows them to circle the earth
twice each day while emitting a very low power signal. The signals are timed by clocks
that are highly accurate and are received by one of 5 ground stations. These ground stations
use the precisely timed signal to determine each satellite’s exact position in orbit. Your
GPS receiver can “hear” the signal sent by the satellite. By calculating the position and
distance of at least 4 satellites, accurate latitude, longitude and altitude location information
can be determined. WAAS adds to your GPS’s accuracy. WAAS stands for Wide Area
Augmentation System. WAAS was designed by the United States Federal Aviation
Administration, primarily to add in the accuracy of GPS for planes. WAAS consists of the
group of additional ground stations placed at known and precisely located spots. These
ground stations then work with a master station to correct the satellite signals improving
accuracy to within nearly 3 meters. WAAS reception may be turned on in the SET page
menu-however, the default setting is “Off” due to the additional battery drain it causes.
