MMC space for two key purposes.

First, you can backup your onboard GPS Data Files by copying them to the

MMC. Since the MMC is removable (like a floppy disk or a cassette tape),

you can store these GPS Data Files on a personal computer equipped with

an MMC card reader. (Or store them on a pocketful of MMCs, if you don't

have a computer.) Our MapCreate mapping software can save, edit or cre-

ate its own GPS Data Files, which can be copied to the MMC and then

loaded from the MMC into Atlas's memory. (NOTE: No matter where they

come from, GPS Data Files must be loaded from the MMC into memory be-

fore Atlas can use them.)

The other key GPS use for MMCs is storage of special high-detail, custom

maps, which you can produce on your computer with our MapCreate soft-

ware. These MapCreate custom maps contain much greater detail than the

basic background map. These Custom Map Files (file format *.lcm) can

also be shared between Atlas’s, other Brunton GPS or sonar/GPS units

and personal computers.

You make your own Custom Map Files with our MapCreate software, but

you don't have to. We also sell ready-to-use InfoCards™. These custom

maps are pre-loaded on MMCs. (No computer work required!).

Atlas automatically reads Custom Map Files directly from the MMC or SD

Card. To use a custom map, all you need to do is slide an MMC containing a

map into the unit.

Introduction to GPS and WAAS

Well, now you know the basics of how Atlas does its work. You might be

ready to jump ahead to Section 2, Installation & Accessories, on page 9,

so you can install the batteries. Or you might want to see how our text for-

matting makes the manual tutorials easy to skim. If that's the case, move

on to "How to Use This Manual" on page 7. But, if you want to understand

the current state of satellite navigation, look over this segment describing

how GPS and its new companion WAAS work together to get you where

you're going.

The Global Positioning System (GPS) was launched July 17, 1995 by the

United States Department of Defense. It was designed as a 24-hour-a-day,

365-days-a-year, all weather global navigation system for the armed forces

of the U.S. and its allies. Civilian use was also available at first, but it was

less accurate because the military scrambled the signal somewhat, using a

process called Selective Availability (SA).

GPS proved so useful for civilian navigation that the federal government

discontinued SA on May 2, 2000, after the military developed other meth-

ods to deny GPS service to enemy forces. Reliable accuracy for civilian

users jumped from 100 meters (330 feet) under SA to the present level of

10 to 20 meters (about 30 to 60 feet.)
