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.

What is causing the forward motion of a stopped vessel using continous bow thruster action?

Following a surf riding and broaching incident and subsequent collision by an experienced vessel operator, QinetiQ have been undertaking extensive investigations into the risk mitigation and safety management of pilotage operations. This presentation looks to discuss the risks presented during pilotage services, and provide a critical review of vessel design and service delivery approaches to understand the potential risk mitigations and management of pilot boat safety.

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 video has been recut and edited by the creator Hugues Cauvier. Previously there were three episodes, which have now been combined into one.

The Pilots’ Association of the Bay and River Delaware have ordered another pilot boat from Gladding-Hearn Shipbuilding, Duclos Corporation. It’s the pilots’ association’s fourth Chesapeake Class launch and eleventh pilot boat built by the Somerset, Mass., shipyard since 1957. Delivery of the new pilot boat is scheduled for 2024.
