2. Having trouble finding your way?

7. GPS is funded by and controlled by the US Department of Defense (DOD), and is operated by the US military Satellite signals enable the GPS receiver to compute position, velocity, and time. Four GPS satellite signals are used to compute positions in three dimensions and the time offset in the receiver clock. What is GPS?

8. A GPS device receives signals from satellites orbiting the earth to triangulate your location, which will be given as a global address. A GPS device can lead you to a previously marked location, much like a compass. How does GPS work?

22. What is Geocaching? One of the fastest growing “new” sports. Has participants in many countries outside of the US and Canada. Is a modern day active treasure hunting activity that allows you to use GPS – and therefore a “global address” – to locate a cache.

23. Are there rules for Geocaching? Yes, there are: –1. Take something from the cache –2. Leave something in the cache –3. Write about it in the logbook –4. Do not move the cache
