Oban Trial Demonstrates Galileo Navigation
17 Apr 2008
The demonstration, which was coordinated by the Research and Radionavigation Directorate of the General Lighthouse Authorities of the United Kingdom and Ireland, focused on port and harbour approaches and involved the temporary positioning of ground based Galileo 'pseudolite' devices at selected sites around Oban bay and its approaches. These pseudolites were used for navigation by the Northern Lighthouse Board vessel NLV Pharos, which acted as the demonstration vessel.
The demonstration, which involved a vessel navigating through the use of Galileo type signals for the first time, had a number of key objectives. It showed how Galileo could provide a seamless and continuous performance in the transition from coastal navigation, through port approach and port navigation.
NLV Pharos was manoeuvred inside the bay, using the Galileo pseudolites, to deploy a new IALA Emergency Wreck Marking buoy at two locations. Automatic Identification System (AIS) was used to place a 'virtual' buoy to mark a hazard. This enabled observers to view new aids to navigation being developed by the General Lighthouse Authorities of the United Kingdom and Ireland, including the new emergency wreck marking buoy, virtual aids to navigation and AIS.
All pseudolite transmission frequencies were carefully selected to ensure that there was no interference with GPS reception in Oban bay and a Notice to Mariners was issued to notify local shipping of the trial.
Summing up the success of the demonstration Roger Lockwood, chief executive of the Northern Lighthouse Board said, 'This has been a most successful day, not only in bringing together key people from around Europe but also principal users of our waters, including port authorities and the professional maritime bodies to hear about the advancements being made in marine navigation. It has been a pleasure to welcome everyone to our excellent base facility in Oban and for our ship NLV Pharos to take an effective role in this demonstration of future technology.'
