How Lowrance GPS Works
You'll navigate faster and easier if you understand how the GlobalMap
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 on ahead to Section 2,
Installation & Accessories on page 11. If you're new to GPS, read on, and
you can later impress your friends with your new-found knowledge.
First, think of your unit as a small but powerful computer. But don't
worry — we made it easy to use, so you don't need to be a computer ex-
pert to find your way! The GlobalMap includes a keypad and a screen
with menus so you can tell it what to do. The screen also lets the unit
show your location on a moving map, as well as point the way to your
destination.
This gimbal-mounted GlobalMap uses an external antenna/receiver
module, which makes the whole system work 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.
Your unit listens to signals from as many satellites as it can "see"
above the horizon, eliminates the weakest signals, then computes its
location in relation to those satellites. Once the GlobalMap figures its
latitude and longitude, it plots that position on the moving map shown
on the screen. The whole process takes place several times a second!
The performance doesn't stop there. Stored in the permanent memory
of each unit is a basic background map of the
entire world.
