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.

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).

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

Before you, you see my third article on pilot boarding arrangements. After my two previous articles ‘1000 ways to secure a pilot ladder’ and ‘1000 ladders around’, I have received a lot of feedback and also questions to get deeper into the matter of combinations and embarkation platforms.

We take a look at some of the dangerous ladder arrangements provided by ships when attempting to take maritime pilots on board. Our message is simple: if you are offered an unsafe or non-compliant ladder, do not board!

Two new locks were introduced in 2009 for training in the new Panama lock conditions with or without tug(s). This video shows the famous "piston effect" when entering the lock at an impressive speed of 10 knots with a high blockage factor.
