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...

This safety video examines the safe set-up of pilot ladders and details the safety checks that should be carried out before using a plot ladder to ensure a safe boat transfer.

Electronic warfare in the Baltic Sea is escalating rapidly, with GPS and AIS disruptions posing growing risks to maritime navigation. Russia’s hybrid strategy is targeting both safety and stability in one of Europe’s most critical shipping regions. Pilots and crews now face a new reality: navigating under threat.

Today, Nautitec took residence of their new offices at the construction site of the “Friesenbrücke” in Weener, the railway bridge which is connecting Weener to the Netherlands.
