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...

SAMMON - the IDEAL tool to identify manoeuvring capabilities of a ship - SAMMON - learning the EFFECTIVE way

A unique 3D video endeavoring to raise the awareness of the seafarers about a very important, critical, and essential piece of equipment on board. Basic in design, but high on purpose, the mistakes incorrect handling of this equipment continue to result in Near Miss, Incidents and accidents.

At Safehaven Marine it was great to be able to launch a new pilot boat for the Port of San Ciprian in Spain after nearly 2 months of Lockdown. She was nearly finished at the start of the lockdown. It sure was nice to be on the water again, even with social distancing.
We wanted to do something nice to lift everyone's spirits during these challenging times around the World, so we did a fly past our home Port of Cobh in Thunder Child II (Safehaven’s Transatlantic record attempt vessel) in...
