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.

New guidance for PBAs with trapdoors. Released 4.11.2020 at NZMPA Conference in Dunedin, NZ. Distinct difference to suggestions in many other countries, is that we challenge operators who have the ladder suspended from the accommodation ladder (gangway) and not secured to the ship. SOLAS states that pilot ladder shall be secured to the ship, and securing strongpoints, shackles and ropes shall be as strong as the sideropes.

Entrainement sur simulateur des pilotes du Havre-Fécamp : pilotage des barges transportant les embases gravitaires du champ éolien offshore de Fécamp. Plus de 500 H de formation et de travail préparatoire ont été nécessaires pour préparer ces opérations de pilotage portuaire exceptionnelles

Practical samples for manoeuvres for ships going astern - as Stern-First-Method SFM. Introduction using as sample from the Master Thesis by Karel Wiegert for an arrival manoeuvre of a cruise vessel in Southampton port with a Twin-screw vessel under strong current. The same manoeuvre with the same ship model was used to show the advantage of Fast Time Simulation FTS using the SAMMON Planning Tool. This goes much faster than the manoeuvres in the real time simulator - and it can even be...

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

As the sun comes up on the last day of 2021, the last shipping day for Brisbane Marine Pilots, our pilots out on the water serving the Port of Brisbane Pty Ltd, as they have done every day since 1st January 1989.

Experiences from Australia: No two days are the same for a marine pilot in a busy port such as Esperance, but Mr MacAdie wouldn’t have it any other way.
