1 The Global Positioning System (GPS) Understanding the functional characteristics and navigational attributes of GPS devices for the motorcyclistRick BakerBlue Ridge Wings, VA CH Y20-Apr-08
2 CAUTIONThe Blue Ridge Wings provide this information to its participants to familiarize motorcyclists with the functional capabilities and navigational attributes of the Global Positioning System. The GWRRA or VA District or Chapter Y does not render any professional navigation or piloting services or advice related to the actual use of GPS nor accepts any liability for user use of the GPS system. Use of the GPS for navigation on board a motorcycle can be hazardous if not used correctly!Because of the rapidly changing nature of the GPS system, the wide array of GPS commercial receiver products available, and the potential interference which may degrade the accuracy on such systems, the contents and recommendations contained in this presentation may become outdated or inappropriate for situations actually encountered on the highway existing at the time of the use of any such systems.We strongly encourage GPS users to consult their specific product documentation and GPS and Motorcycle Operator’s manuals for detailed instructions on proper operations and maintenance and for applicable precautions on the use of the product.
3 Why Rick Baker?23 years of Marine Navigation, C. Bay, Pacific Ocean, Atlantic Ocean, Bahamas, and CaribbeanLORAN C Navigation Since 1993GPS and Chartplotter Navigation since 1998Navigation Instructor since 1992, both power and sail boatsClassroom and On-The-WaterHighway User of GPS since 2004 on Motorcycles and CarsAir Force Master Space Operator and Master MissilierDuties included:Military uses of GPSAdjunct to DoD Office of Space Policy
4 What We Covered – Part IAn overview of the Global Positioning System (GPS)What it isHow it worksThe Types of GPS receivers availableStandard GPS receiversWide Area Augmentation System (WAAS) receiversCompared Accuracies – See next slide

6 Why GPS On A Motorcycle?Listening to GPS “Turn” Directions is the Number One Safety Feature of Using a GPS For Motorcycle Navigation vs. Looking at a Map or Turn-by-Turn DirectionsSolve “I’m Lost” SituationsScenic Route Choices Are Amazing and RewardingChoose “Off Interstate” Routes More OftenEliminates “Most” Wrong Turns and U-TurnsBetter “Lead” Team Rider

9 Using a GPS Receiver to Navigate Where Am I?Addressed by the GPS unitWhere Am I Going?Addressed by the Human Motorcyclist: The Rider/CoRiderWhat Route Should Be Used?Can be addressed by various points in the GPSSelected by MotorcyclistWhen Will I Arrive?Can be calculated by the GPS unitAre There Any Hazards to be Avoided?May be downloaded continuously by the GPS!
10 Waypoints Waypoint Via Point: A route point without much other meaning Unique name or numberLatitude and LongitudeA Point of InterestSomewhere We’ve Been BeforeSomewhere We’d Like To GoVia Point: A route point without much other meaningPoints of Interest stored in GPSPoints to Navigate toBusinesses and other Community Landmarks for ReferencePlaces to avoid – dangerGPS UnitTotal number of Waypoints depends on GPS unitPre-programmed or entered with “mark” button or cursor
11 Waypoints Once the waypoints are stored They can be editedRenamedMovedFlagged with unique symbolNotes added (some units)They can be called up individuallyThey can be assembled into a “route”Waypoints will remain in non-volatile memory when unit is turned off
12 After the Waypoint is Selected GPS computes the courseFrom your current locationUsing road preferencesQuickest (least time)Shortest (least distance)Most ScenicThings to AvoidCustom AvoidsSelect Detour ZonePlots courseFrom current location to waypointMap Page – On RoadsList of WaypointsPoints of InterestFindsThe GPS Unit DOES NOT:Qualify the path for hazards or traffic jams, unless you:Use FM Traffic Radio ServiceUse XM Traffic RadioUse “DASH” GPS UnitYou need Maps to:Plan your tripBack up your GPS UnitSee the bigger pictureAs soon as you have entered a waypoint for navigation, the GPS goes to work and computes the course (Bearing) and distance from your current location to that waypoint.It also plots a line on the Map Screen from the point that you activated the waypoint to the waypoint. And, it sets a highway on the Highway Screen that corresponds to the same path.You are navigating!!Caution – REMINDER – the GPS has no knowledge of what lies between you and the waypoint. It’s up to you to check on a chart to make sure the path is clear!
13 Creating a Route GPS can store a route Routes Waypoints are just Sequence of waypoints or via pointsCreates a sequence of “legs”Route may have a nameRoutesCan be editedCan be activated – forward or reverseWaypoints are justNames, Numbers, or L/Lo coordinatesImportant to not overly rely on waypointsUse Via Points instead of multiple WaypointsFor turnpoints without much further meaningShould scrutinize route for accuracy before using!The GPS can record a sequence of stored waypoints at a Route.Routes have names, and can be activated in either direction.
14 Planning a Trip A Trip Usually Consists at Least Two Points: Starting and Stopping Points >> WaypointsAn Interesting Trip Consists of Varied Roads and SightsGPS can determine quickest, shortest, and scenic routeYou can Custom Build A Route with Waypoints and Via PointsUse Via Points for Trivial stops and turnsBest Done Prior To Trip (Home, Office, Garage)You Can Change A Trip’s RouteIn Your Hotel Room: On the GPS, On A Laptop – New PlanningOn The Motorcycle:Just Do It – The GPS “Recalculates” The Route Based On Last Route Preference: Quickest, Shortest, or ScenicAdd or Delete Via Points and Waypoints - CarefulMake A Detour Around Construction or Traffic DelaysUsing GPS, planning a trip involves a starting waypoint and a destination waypoint

59 How To Make Navigation Easier Using GPSPrecise Position – continuously – It’s Thing!Best Rider User Approach:Create pre-qualified routes at homeString Via Points together to create RoutesQualify them to be free of obstacles, on the roads you want to ride, and within ride timelinesOn-the-Road – follow the routesOnly need to refer to maps on occasionKey – stay on course to next Waypoint or Via PointRemember – You are the human in the system!If you want to deviate, let GPS recalculate your route on the “fly”Use the “Detour” function in traffic back ups
