How GPS works? Trilateration explained

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 shows an introduction on the Pull-out Test-Manoeuvre and describes the procedure how to steer through this simple manoeuvre: Turning circle and then put the rudder amidships. The final rate of turn allows to identify stable and unstable conditions.

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.

Improvements to pilots’ situation awareness (SA) in maritime navigation are critical to reducing human errors, which have caused 75% to 96% of marine accidents over the last few years.

The Good Practice Guide for Pilots 2021 describes the knowledge and skills (technical and non-technical) that the NZMPA believe all pilots should aim to achieve and maintain. It is written primarily for pilots for their own guidance and professional development, but can be used as a framework for pilot training, proficiency and assessment. It is referenced to NZ Maritime Law and Codes.

Apparently there were two crew members on board, but no pilot. One of crew was recovered and declared dead, another one, skipper of the boat, is missing.

Brisbane Marine Pilots launched their new website. Go to www.brisbanepilots.com.au to find out more about BMP. There you will also find useful links to the Port Procedure Manual, Pre-Arrival information for visiting vessels, tides and weather updates.
