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.

A portable pilot unit (PPU) is a portable navigation aid system designed specifically for ship pilots, such as the SIRIUS series from TRENZ in Germany (www.trenz-ppu.com).

Simulation of pilots and tugs in the Port of Brownsville from the inlet to the berth

This updated video shows how easy it is to develop an arrival plan with the SAMMON Planning Tool. As a sample the arrival from appraoch until the berth to Ft. Lauderdale is used under strong current of 2kn. At the simulator training courses where we used this tool for preparation of a manoeuvring plan during the briefing sessions all nautical officers involved stated afterwards: "Why don't we have this tool on our ships?"

With ships as large as 175 feet wide and a channel a maximum of 500 feet wide, how to you safely pass? Former Houston ship channel pilot, Lou Vest, explains how ships fight against hydrodynamics to pass with such narrow margins.

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.

AMSA notes with concern that since November 2017 several pilots’ lives have been placed at risk, in six separate incidents where man ropes have parted, or its securing point has failed. In addition, AMSA regularly receives reports and complaints about non-compliant pilot transfer arrangements

Shipbuilder Gladding-Hearn Shipbuilding, Duclos Corporation, said it has delivered by road transport a new pilot boat to the Lake Pilots in Port Huron, Mich. The Resilient Class high-speed launch Huron Pride is the pilots’ third boat built by the Somerset-Mass. shipyard since 1979.
