An IEEE VTS and Control Systems joint meeting . . .

Future Trends in Marine Navigation Technology, Systems and Applications

Sam Ryan - Department of Fisheries and Oceans, Ottawa

Monday 26th November 2001, 7.30 pm

The Crowsnest, Naval Officer's Mess, 78 Lisgar St

Current marine navigation and hydrographic positioning requirements for harbour & harbour approaches and inland waterways are reviewed. Emerging requirements for three-dimensional navigation in constricted navigation channels are then discussed. An analysis of GPS to meet these requirements is then presented. The limitations of the current GPS are illustrated through selected examples. The ability of the forthcoming GPS II and GPS III and the European Union's GALILEO to meet current and emerging requirements is then addressed. It is predicted that the use of a combined GPS/GALILEO system by the end of the decade would have a massive impact on marine navigation and positioning accuracy and reliability. One of the GALILEO services, namely the Control Access System, will provide the integrity function for the signal in space. At the user level, combination of GPS II and GALILEO would provide an excellent RAIM availability. A cost-effective and reliable real-time kinematic (RTK) service, anchored on the current Canadian Coast Guard DGPS Service, could be made available in inland waterways for three-dimensional, sub-decimetre navigation and positioning.

Sam Ryan graduated with a Bachelor's Degree in Electrical Engineering from Memorial University of Newfoundland in 1992. Since then he has worked for the Canadian Coast Guard on various navigation and positioning projects. Most recently he was involved with the design and implementation of the Canadian Coast Guard's Marine DGPS System. Currently he is finishing his Ph.D. degree in Geomatics Engineering at the University of Calgary, and has reported back to the Canadian Coast Guard in Ottawa.
