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.

Gavin Buchanan on YouTube: "Some of the best Ship Handling videos available online. Studying for my Master 3000 and have found these videos incredibly helpful. Thank you for making these free for students!"

Port operations, whether these are being performed on water or on land, are often not without risk. Pilots boarding a ship while sailing, navigating through narrow passages, collision avoidance with other smaller or larger vessels, discharging and moving cargo on land, walking between container handling equipment and trucks…

'Shallow Water Effects' - The New KARCO video which promises to bring immense training value for navigators, has been developed using very effective 3D Animation &VFX.

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...
