What is the Global Positioning System
The Global Positioning System, or GPS, has grown from modest
beginnings to a current position as a vital component of navigation,
and mapping throughout the world.
Long ago, the stars, sun,
a compass, a watch and sextant were used to determine your position. Now,
satellites and electronic equipment can do the job with less work
and much greater accuracy. GPS is a navigational
system using satellite signals to fix the location of a receiver
on or above the earth's surface.
As you move through this lesson you will find various links
to web sites that contain information about GPS, how it works
and how it is used in transportation. It
is your job to thoroughly investigate these web sites and collect information,
by taking notes. After you have searched these web pages and researched
GPS you will take a quiz on this information. A crossword puzzle
is also included for testing your knowledge. Finally, you will create a presentation
about what you have learned about GPS and transportation.
An optional unit on Topographic Mapping may be assigned. In this module,
you will learn about topographic maps and make a topographic
map from GPS data.
