How does GPS work?

Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

Maritime pilots trace the roots of their profession back to the ancient Greeks and Romans when incoming ship captains employed experienced local fisherman to guide their merchant vessels safely into port. It’s a legacy of skill, strength, and sharp wits, and our Houston Pilots (“Pilots”) have been meeting vessels at Galveston’s bar to carry on these proud traditions for just shy of 100 years.

Thanks to Jacqui Kenyon, Chevi King and Kate Delisky for joining Jeanine Drummond on this webinar to discuss their careers and pathways into marine pilotage. The audience was a great mix of experienced marine pilots and newer maritime industry participants, as well as school aged children, with people joining us from Australia and overseas. It was an opportunity to create greater awareness of the maritime industry, and the important role marine pilotage plays in protecting our port...

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

Required tug power and number of tugs needed in variable conditions of wind, current and waves isin most cases an assessment made by pilots based on their professional experience. However, assessments will raise questions by lawyers if something goes wrong. They will use tools to calculate what really is needed with respect to tug power and number of tugs. They have furthermore the advantage of time.

Here’s a cool little video of the rough weather sea trails of ‘Port Láirge’ The Port of Waterford’s new Interceptor 48 pilot boat ready to be delivered next week. We had two days of rough weather, a Force 8 with 3.5m seas putting up some surf breakers over the Daunt and a second day with winds reaching Force 10 offshore, with 55kts of wind and 5m swells, allowing us to properly test her capabilities ensuring she's fully fit for purpose for the pilots and crew. Doing so we captured some...
