Garmin GPS Training – Bronze level

transcript

• 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?

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.

5 Metres

The basic principles of GPS Navigation

• Waypoints

• Routes

• Tracks

• Goto’s

• Track Logs

• Trackback

• Headings and Bearings

• Digital Maps

All GPS Receivers offer the following

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.

1) A route is a series of waypoints and GOTO’s – linked together to create a path to follow.

What is a Route?

• A route is a series of waypoints and GOTO’s – linked together to create a path to follow.

What is a Track?

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

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
