How does the GPS System work?

The Global Positioning System is based upon 24 satellites that circle around the

Earth. By receiving the signals from the satellites, the GPS receiver can calculate

its position with an accuracy of down to a few metres. The GPS receiver needs

to receive signals from at least 4 satellites simultaneously in order to calculate a

position. The system works no matter where on Earth you are and 24 hours a day,

365 days a year.

Why should I buy a GPS?

A GPS is a valuable aid to navigation and in some situations, could prove essential

to those who need precise POSITION, DIRECTION, ALTITUDE and SPEED. Using

a GPS makes navigation even more interesting and fun. It also makes it much safer

for all concerned.

What kind of GPS should I buy?

If your main concern is boating, or use in open terrain in normal temperatures, you

will  nd that virtually all GPS instruments work more or less equally good. If you are

a true outdoor user, with demands of functionality in extreme temperatures, under

tree coverage and in extreme wet and snowy environments the Multi-Navigator™

is the perfect choice.

Can I use a GPS indoors, or in a car?

The GPS receiver needs to be in contact with the satellites in the sky and does not

normally work indoors. However, in a car, where the GPS signal can travel through

the windows, it does normally work  ne. Remember though, that the GPS always

works best with a clear view of the sky.

Does the Multi-Navigator™ have maps?

The Multi-Navigator™ is built for tough, off-road, outdoor use. A graphic display,

which is needed to show a map, will not work in extreme temperatures. On top

of this, the maps available today for these kinds of products are very schematic,

showing major roads etc but not information about topography and other detailed

information which is essential when in wild country and that can be found on the

paper map.
