NOTE:
The above memory capacities refer only to the iFINDER's on-board
memory. The amount of GPS data you can record and save for re-
call later is only limited by the number of MMC cards you have.
How the iFINDER Works
You'll navigate faster and easier if you understand how the iFINDER
scans the sky to tell you where you are on the earth — and, where
you're going. (But if you already have a working understanding of GPS
receivers and the GPS navigation system, skip ahead to Section 2, In-
stallation & Accessories on page 11. If you're new to GPS, read on, and
later you will 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 the iFINDER easy to use, so you don't need to
be a computer expert to find your way!) The iFINDER includes a key-
pad and a screen with menus so you can tell it what to do. The screen
also lets the 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 we'll tell you more about that in the upcoming segment
introducing you to GPS and WAAS.)
The iFINDER listens to signals from as many satellites as it can "see"
above the horizon, eliminates the weakest signals, then computes its loca-
tion in relation to those satellites. Once the iFINDER figures its latitude
and longitude, it plots that position on the moving map shown on the
screen.
