  1. Proof of Concept Testing AIS EPRIB L Yarbrough / Greg Johnson

  2. AIS • Automatic Identification System (AIS) • Ship to Ship broadcast of own ships data to all ships in vicinity. • MMSI (identification) • Location (GPS) • + more (course, speed, etc) • AIS carried by SOLAS vessels, and growing population of ships world wide. • AIS receivers now on many of worlds MPA L Yarbrough / Greg Johnson

  3. 121.5 MHz • Legacy Homing Frequency • Poor DF results • Short range – mostly > 10nm • Easily Attenuated – blocked by body, rafts, etc. • DF not carried by AMVER vessels, or most ships. L Yarbrough / Greg Johnson

  4. SART • SART -Search and Rescue Transponder • IMO approved device to locate survival craft. • RADAR SART L Yarbrough / Greg Johnson

  5. AIS SART • SART device with AIS instead of RADAR L Yarbrough / Greg Johnson

  6. AIS EPIRB • Idea – replace 121.5 MHz homer in EPIRB with AIS transmitter. • Send AIS (Class A) message 8 times a minute, updating every minute. • Testing: • Northern Lighthouse Board – Oban, Scotland. 2008 • USCG – Key West Jan 2009 • USCG – Hawaii Jan 2010 L Yarbrough / Greg Johnson

  7. AIS EPIRB Testing in HI L Yarbrough / Greg Johnson

  8. AIS Test Results L Yarbrough / Greg Johnson

  9. Next Step • IMO Approval • Standards developed • Product development • Product Sales L Yarbrough / Greg Johnson
