  1. The use of Technology in Race Management Peter van Muyden

  2. From To

  3. Agenda • Global Positioning System (GPS) • GPS settings • GPS accuracy • When to use a GPS and when to use a compass • GPS based mark laying • Advanced GPS’s • Target time calculation • Real-Time Weather Station

  4. Global Positioning System (GPS) • Established in 1973 to overcome the limitations of previous navigation systems • The first GPS satellite was launched in 1978. • A full constellation of 24 satellites was achieved in 1994. • May 2, 2000 "Selective Availability" was discontinued (this improved accuracy from 100M to 10M) • Position calculation is based on triangulation of satellites and signal elapsed time

  5. GPS settings • Nautical Miles • Wide Area Augmentation System (WAAS) on • Time Format 24 hour • Current Date • Current Time • Location format dddmm.mmm’ • Map Datum WGS 84 • North Reference Magnetic

  6. GPS accuracy • 1983 +/- 100 Metres Original GPS signal • 2001 +/- 10 Metres Selective availability removed • 2007 +/- 3 Metres Wide Area Augmentation System (WAAS) enabled • Survey grade GPS systems +/- 2MM

  7. When to use a GPS and when to use a compass

  8. GPS based mark laying (Calculating vs Pinging) Traditional steps (Pinging) Mark boat 4 pings the signal boat Mark boat 4 projects and lays Mark 4 Mark boat 1 pings Mark 4 * Mark boat 1 projects and lays Mark 1 Mark boat 2 pings Mark 1 * Mark boat 2 projects and lays Mark 2 Mark boat 3 pings Mark 2 * Mark boat 3 projects and lays Mark 3 Etc *This adds a +/- 16 Metre error for each Mark. Which can be 64 Metres at Mark 3

  9. GPS based mark laying (Calculating vs Pinging) Calculating Signal boat calculates Mark 4 Signal boat radios Mark 4 ( course origin) coordinates to the mark boats Mark boat 1 projects and places Mark 1 * Mark boat 2 projects and places Mark 2 * Mark boat 3 projects and places Mark 3 * Mark boat 4 projects and places Mark 4 * *Maximum error of +/- 8 Metres for the marks.

  13. Computer based course configuration GPSLoad Biscayne Bay

  14. Advanced GPS’s with built-in radios 4Mile range • Broadcast location • Transmit Waypoints • Poll location

  15. Target time • Reasons for Target Time • Schedule • Class rules • TV broadcast time slot • Time limits • etc

  16. Real-Time Weather Station GPS Ultrasonic technology 3 Axis Compass Barometer Temperature Wind direction (true, apparent) Wind speed Uses NMEA 2000 network
