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.

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.

Maritime pilots work in an irregular deployment system (rotation system) with unpredictable work assignments under high levels of physical and mental stress. Fatigue or chronic diseases, e.g. coronary heart disease, peptic ulcers or gastritis can occur as a consequence.

Practical samples for manoeuvres for ships going astern - as Stern-First-Method SFM. Introduction using as sample from the Master Thesis by Karel Wiegert for an arrival manoeuvre of a cruise vessel in Southampton port with a Twin-screw vessel under strong current. The same manoeuvre with the same ship model was used to show the advantage of Fast Time Simulation FTS using the SAMMON Planning Tool. This goes much faster than the manoeuvres in the real time simulator - and it can even be...

We have reached Port Said at the northern end of the Suez Canal. Could not have been a more enjoyable adventure. Thank you Suez Canal Authority for the two excellent pilots, specially Emad, and the support specially at Ismailia.
Editor's note:
Other countries, other habits: especially when it comes to safety standards. Life jackets, for example, are not to be seen here.

On Mar 23, 2021, at around 0500 UTC, Ultra Large Container Vessel EVER GIVEN ran aground in the Suez Canal north of Suez. The incident caused a blockage of the Suez Canal, extensive vessel traffic jams, and disruptions in the maritime supply chain. Watch a 3D video simulation of the last 90 minutes of her journey before the accident happened. The video is based on AIS vessel position data received by FleetMon.
