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.

At Humber Maritime College we have state-of-the-art marine simulators to teach our Merchant Navy cadets in an environment close to reality, preparing them for a career at sea.

How GPS works? Trilateration explained

The Australasian Marine Pilots Institute is presenting a webinar via Zoom about ports providing ECDIS routes and passage plans to ships as part of the pre-arrival process.

It will take place on Thursday 11 February 2021 at 19:00 AEDT (08:00 UTC) and is free for AMPI/IMPA/UKMPA/NZMPA members. Non-members are also welcome to attend.

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

Here’s some cool video footage we captured of the Cork Pilots in their Interceptor 48 pilot boat ‘Failte’ undertaking pilot transfers off Cork Harbour during the recent days of strong SE gales. Roches Point lighthouse recorded 50kts of wind on the 13th as the Cosco bulk carrier passed and the Cork wave buoy 2nm off the harbour entrance recorded waves to 6.7m at the time. The pilot boat coxwain managed to get alongside and safely disembark the pilot despite the challenging sea state....
