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.

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.

“The world of hydrography is going digital and the S-100 standard is an essential component of that move.” See how the Canadian Hydrographic Service has led Canada to become one of the first countries in the world to start using the S-100 standard, and how implementing these standards will benefit Canadians through increased safe navigation in Canadian waters.

The Nautical Institute (NI) and the International Maritime Pilots’ Association (IMPA) have been concerned for many years at the needlessly high rate of Pilot Ladder casualties. The NI is continuously reminded of the problem from its Members and through its Mariners’ Alerting and Reporting Scheme (MARS). The issue features frequently in our publications, and we recently dedicated an edition of our award winning magazine The Navigator to the topic, emphasising the importance of good...

Here’s a nice little video of rough weather sea trials that coincided with ‘Storm Agnes’ last week in the Interceptor 48 pilot boat ‘Svitzer Oued Laou’. The storm produced some pretty big waves at the entrance to Cork Harbour, and strong winds during the height of the storm. We managed to capture some cool footage from Roches PT lighthouse. It was fairly rough, although by not coinciding with the ebbing tide conditions aboard were quite comfortable, and our Pilot 48 handled it effortlessly...
