How iFINDER Works
You'll navigate faster and easier if you understand how iFINDER scans
the sky to tell you where you are on the earth — and, where you're go-
ing. (But if you already have a working understanding of GPS receivers
and the GPS navigation system, skip on ahead to Section 2, Installation
& Accessories on page 9. If you're new to GPS, read on, and you can
later impress your friends with your new-found knowledge.)
First, think of your iFINDER as a small but powerful computer. (But
don't worry — we made iFINDER easy to use, so you don't need to be a
computer expert to find your way!) The iFINDER includes a keypad
and a screen with menus so you can tell it what to do. The screen also
lets iFINDER show your location on a moving map, as well as point the
way to your destination.
This pocket-sized computer also contains an antenna and specialized
scanning receiver, something like your car radio. But instead of your
favorite dance tunes, this receiver tunes in to a couple of dozen GPS
satellites circling the earth. (It will also listen in to the WAAS satellites
in orbit, but more about that in the upcoming segment introducing you
to GPS and WAAS.)
iFINDER listens to signals from as many satellites as it can "see" above
the horizon, eliminates the weakest signals, then computes its location in
