8 Outline SG Ch. 5 Objectives Using GPS As a Navigation Tool What GPS Can Do GPS Receiver Keyboard Functions Typical GPS Screens Entering Waypoints Into the GPS What the GPS Does When You Select a Waypoint Navigating Using GPS and Waypoints

9Objectives Using GPS As a Navigation Tool GPS Keyboard Functions Typical GPS Screens Constructing Routes Checking Waypoints and Routes Stored in GPS Activating Waypoints For Navigation What the GPS Does when a Waypoint Is Activated The Process of Navigating With GPS Plotting Your GPS Position On a Chart

10 Using GPS As a Navigation Tool GPS Without Charting Software –Like Using Loran: It will give you position on the water: then need to plot on a paper chart –Like Loran, could store waypoints on GPS for use while on the water GPS With Charting Software –Like a Chart-plotter –Can Pre-Plan –Can punch in waypoints while on the water and GPS will show track. Can build routes

11 What GPS Can Do Provides position: L and Lo Can calculate a course to steer between waypoints It can calculate estimated arrival time, ETA

12 What GPS Cannot Do Warn of hazards (USPS) –Translation from USPS: You have to look on a chart to see if the course is safe –Actually it has a proximity warning function Determine water depth

13 GPS Keyboard Functions Power Button: On/off Cursor Key: rocker switch Enter Button/ Mark: Yes; enters current waymark (on the water) Menu Button Quit Button: like an escape key or back button Go To Button Page Button MOB Button: Man Overboard Zoom Buttons

24 Entering Waypoints Into the GPS On the Water: hit the Mark key to enter the current location as a waymark Use digital charts and pre-planning to determine location of waypoints and then enter L and Lo into GPS Choose waypoints on a paper chart and use dividers to measure L and Lo for entry into GPS

25 On Page Mark “ On the Water entry”

26 Waypoint tool Select Buoy L & Lo MapSource Software: “Computer Pre-planning Entry”

27 Entering Waypoints Loran C GPS w/o Chart L & Lo Plot On a Paper Chart GPS with Chart Software (handheld Chart-Plotter) Plots Waypoints On the GPS For You

33 Press enter key returns you to buoy page; then press page key to go to map page. Note Waypoint is denoted “SB” while the buoy is “Sb”

34 SB Waypoint overlaid On Sb buoy To check waypoints from here, Press menu key twice to go to Main menu

35 Select Points

36 Select Waypoints to see list of waypoints

37 Press enter key to select “SB” waypoint

38 Then press enter key To go to “SB” Waypoint Page

39 Options: With rocker arm you can 1.View on map page 2. delete

40 What the GPS Does When You Select a Waypoint GPS compute course to new waypoint, including bearing and distance from current location Plots a line of the activated course on the Map Screen Creates a highway on the Highway Screen
