The document outlines a GPS technology workshop led by Mark N. Lewellen, focusing on the history of navigation, the global positioning system (GPS), and geocaching as a practical application. Participants will learn how to use GPS receivers to find their position on Earth and engage in a hands-on geocaching activity. The workshop is designed to enhance understanding of navigation concepts and is adaptable in length to fit different schedules.

1. Synopsis of My GPS Technology Workshop This is a lesson about global navigating and the Global Position System (GPS). We’ll retrace the footsteps and sea passages of prior explorers. We’ll take a look at the history of navigation and explore the Global Positioning System (GPS). Then we’ll use GPS receivers to locate our position on the Earth and go geocaching (which is a high-tech treasure hunt in the woods using GPS). Presented by Mark N. Lewellen [email_address]

2. Class Objectives Brief History of Navigation How Latitude/Longitude (coordinates) are used Understand the basic concepts of how GPS works Introduction to Geocaching Hands-on experience using a GPS Receiver (GPSr) outdoors Full course is about 3-4 hours but can be scaled back to fit

3. These questions and many more will be answered at my GPS Workshop What would you use to find your way at sea? Hint: It might depend on knowing the time! Did you know the Magnetic Compass was first invented in China but was not originally used for Navigation? Could you figure out your present location with this? Do you know how to use a GPS Garmin Handheld?

4. Where are you now?

5. What's Your Latitude/Longitude? Did you ever wonder how early sailors navigated the seas? It is rather easy to follow a trail or map over land, orienting yourself by following a river, a valley between mountain chains, or a coastline There are many landmarks that you can see to set your course

6. GPS GPS is a constellation of satellites that emit electronic signals while orbiting the Earth A GPS receiver gathers the signals from multiple satellites overhead, then triangulates those signals to calculate its precise location Those receivers can be hand-held or mounted in ships, aircraft and vehicles Global Positioning System

7. Exercise #1 Question? What else does GPS stand for? Answer G reat for P ublic S chools

8. Introduction to Geocaching “ Geo” meaning “Earth” “ Cache” meaning “Storage”

9. What is Geocaching? Geocaching is a high-tech treasure hunt in the woods using GPS Enter the cache coordinates into your GPSr Try to find it yourself!

10. Basic Geocaching Find a cache Take something, leave something Sign the logbook and website HAVE FUN!!!! Finding a Cache Sign the Logbook Have Fun!!

11. How to make it more than a “treasure hunt” Use Geocaching to teach about the wonderful world around us Lessons in nearly any topic can be taught around Geocaching
