Gear Up For Geocaching

At the Geocaching Action Center your den/patrol/crew will be challenged to locate some caches around the camp area. Materials Needed: If you have access to a GPS unit, please bring it with you. If not, don’t worry, one will be provided for you to use. How It Works: A network of about 30 satellites orbit the Earth and at least four of these GPS satellites are ‘visible’ at any time from your location. Your GPS unit listens for these satellites and determines how far away from each one you are. This creates overlapping spheres on which you are located. By finding the intersection of these spheres, the GPS unit can determine your location, usually within a few yards. The more satellites that are visible, the more accurately your position can be determined. Learn more about how GPS works.
