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.

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

Pilotage is being able to navigate safely into and out of a harbour/anchorage/port knowing where you are at all times, where your hazards are and a safe route in/out. This is particularly useful if you are heading into somewhere new or a challenging/busy area – or both!

Online survey among maritime pilots in Germany: job-related stress and strain and the effects on their work ability.

Pilot recruitment has traditionally been based on seniority, and extensive sea experience. However, a more modern approach, hiring younger, motivated candidates with structured training, offers an alternative path with compelling advantages.

“The world of hydrography is going digital and the S-100 standard is an essential component of that move.” See how the Canadian Hydrographic Service has led Canada to become one of the first countries in the world to start using the S-100 standard, and how implementing these standards will benefit Canadians through increased safe navigation in Canadian waters.

From Türkiye to St. John’s, to St. Kitts… and finally Antigua & Barbuda. A journey shaped by effort, endurance, and trust. A 15-meter pilot boat, successfully delivered to the Caribbean, reaching the Antigua Barbuda Port Authority safely after navigating seas that test both vessel and crew. Meet Chief Sam. Built in collaboration with @planetboaat, this is not just another boat. A testament to what happens when experience, engineering, and the right material come together. Crafted in HDPE,...
