• The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for accurate navigation.
• They orbit the earth at a very high altitude of approximately 12,500 miles.
What is GPS?
• GPS receivers take this information and use triangulation to calculate the user's exact location
• GPS Satellites circle the earth twice a day in a very precise orbit
• It is based on a network of 24 active satellites
• They transmit signals to earth.

• Its totally FREE to use
How GPS works
• Using GPS technology you can determine
• Location (Where you are)
• Velocity (Speed you are travelling)
• Time
• It can be used 24 hours a day, 365 days a year in any weather conditions anywhere in the world.
• For optimum performance, they need to see the sky
• GPS Receivers are line –of- sight instruments

How can GPS help you?
• A GPS Can give the answers to the following
Where Am I? How do I get there?
Where should I be?
Where did I go last time? Am I on Course?
How fast am I going?
![Page 5: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/5.jpg)
Getting a position Fix (2D and 3D fixes)
• Once the user's position has been determined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more.
• With four or more satellites, the receiver can determine the user's 3D position = (latitude, longitude and altitude). Horizontal and Vertical Positioning
• A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position
(latitude and longitude) and ability to track movement.

The accuracy of GPS
Example of 5 Metre Accuracy
• A GPS Will give you current position accuracy
• Typically +/- 15 metres 95% of the time
• Less than 7 metres 50% of the time
• +/- 4-5 metres : Typical positioning of new generation GPS Receivers.

The basic principles of GPS Navigation
![Page 8: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/8.jpg)
• Waypoints
• Routes
• Tracks
• Goto’s
• Track Logs
• Trackback
• Headings and Bearings
• Digital Maps
All GPS Receivers offer the following
![Page 9: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/9.jpg)
What is a Waypoint?
• Waypoints are chosen positions, points, co-ordinates or landmarks on the surface of the earth.
• They may be check points on a route or significant ground features, such as a camp or car park, a fork in a trail, or a favourite viewpoint.
• Waypoints can be stored on a GPS Receiver and on a computer.
• These are also locations you may want to return to later.
• Also, waypoints may be entered directly by marking a point at the current position of the unit, giving it a name, and then saving the point.

What is a GoTo?
• A GOTO is a route consisting of one leg - Straight line navigation or as the crow flies
• With your current position being the start of the route.
• And a single defined waypoint as the destination.
![Page 11: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/11.jpg)
1) A route is a series of waypoints and GOTO’s – linked together to create a path to follow.
What is a Route?
![Page 12: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/12.jpg)
• A route is a series of waypoints and GOTO’s – linked together to create a path to follow.
What is a Track?
![Page 13: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/13.jpg)
What is Track Log?
• These points will be strung together on the map page to see where you have been.
• Track Logs are points automatically stored when you are moving
• It’s the electronic equivalent of laying down a “breadcrumb” trail to mark your path
![Page 14: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/14.jpg)
What is TracBack?
• TracBack is a feature that allows you to return along a previously travelled path or route without marking any waypoints
• When you are ready to return to where you started from, the GPS will look at the 100’s or 1000’s of tracklog points
• It then take the most significant 30 points and turns them into a route to lead you back to your starting point
![Page 15: Garmin GPS Training – Bronze level. The Global Positioning System (GPS) was developed by the United States Department of Defense as a reliable means for](https://reader036.vdocuments.site/reader036/viewer/2022062715/56649d935503460f94a79d0d/html5/thumbnails/15.jpg)
