The Global Positioning System (GPS) uses a constellation of 24 satellites to pinpoint locations anywhere on Earth usually within a few meters. GPS determines location by measuring the travel time of signals from at least 3 satellites to triangulate the user's position. With 4 or more satellites, GPS can provide 3D positioning including altitude. GPS was developed in the 1970s by the US Department of Defense and is used widely for navigation in applications like fitness tracking, marine navigation, automotive navigation, and outdoor recreation.

- 2. The Global Positioning System (GPS) is a space age navigational system that can pinpoint your position anywhere on the globe, usually within a few yards or meters GPS uses a constellation of 24 satellites in precise orbits approximately 11,000 miles above the earth. GPS operates 24 hours a day
- 3. GPS uses satellite ranging to triangulate your position. ◦ In other words, the GPS unit simply measures the travel time of the signals transmitted from the satellites, then multiplies them by the speed of light to determine exactly how far the unit is from every satellite it's sampling.
- 4. By locking onto the signals from a minimum of three different satellites, a GPS receiver can calculate a 2D (two-dimensional) positional fix, consisting of your latitude and longitude. By locking onto a fourth satellite, the GPS can compute a 3D (three-dimensional) fix, calculating your altitude as well as your latitude/longitude position.

Editor's Notes
- The satellites transmit data via high frequency radio waves back to Earth and, by locking onto these signals, a GPS receiver can process this data to triangulate its precise location on the globe.
- Although GPS was initially envisioned for military use, the Government realized early on that there would be numerous civilian applications as well. The highest accuracy levels were to be reserved for the military.
- "Map“ screen - (as opposed to just a numerical lon/lat position fix): Makes it much easier to see where you are relative to reference waypoints; Built in Maps: Not absolutely essential, but big help in orientation and estimating distance to nearest roads; Route capability: Twenty Route capability is pretty standard, some have 50. Waypoints - 500+ user entered waypoints are pretty standard, some can store many more. Multiply datum - make sure all the datums you will want to use are included in the GPS you select.
