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.

Maritime Education #5: Pilotage operations in General Cargo ship
An insight to points of attention during Embarkation and disembarkation of Pilots.
This video will be dedicated to my future Maritime students who will be joining General Cargo ships, this is what we normally do here, and this is for your virtual guide.
Thank you subscribers and keep growing so as my contents as well❤️

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.

This video explains the impact of lateral resistance on the turning circle of a vessel using animations. The video explains the term lateral resistance, shows an example of its impact on the turning circle and its associated aspects (advance, transfer, tactical diameter and drift angle).
Contents of this video will benefit mariners preparing for exams (written and oral examinations).

"A performance assessment tool for maritime pilotage operations" - by Jørgen Ernstsen, Norway
When the ship is approaching or leaving a port, a local navigational expert, the pilot, is often provided for assisting the bridge team to safely and efficiently navigate the littoral waters.

Port Revel is used for shiphandling training of maritime pilots, masters and officers on a 5 ha lake with 11 manned model ships representing 20 vessels, and 4 tugs at scale 1:25 and DGPS tracking system. Instructors are former maritime pilots.
Training on the scale models provides experience that could never be gained on real ships for the simple reason that neither ship-owners nor local authorities would allow such risks to be taken. Scale models allow the shiphandler to make mistakes....

Med Marine and IBK Ltd. signed a two-vessel contract for MED-P16 series last November for Nigerian Ports Authority’s operations in Lagos, Nigeria. A year after that, Nigerian Ports Authority takes the delivery of the two high- quality pilot boats. Both units have been despatched on a specialised transport vessel to Nigeria from Turkey.

Brightlingsea Harbour - a mixed leisure and commercial port on the East Coast of England
has recently signed contracts with Seaward to have a new pilot boat built, The demands of Pilot duties as well as working as a patrol boat and harbour launch, and the sea conditions that can occur in the area made the Nelson hulled Seaward the natural choice of vessel.
