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.

'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 explains the IMO resolution on the provision and display of maneuvering information on board ships, particularly the pilot card, wheelhouse poster and maneuvering booklet. the layout and contents of each are explained as well. Contents of this video will benefit mariners preparing for exams (written and oral examinations). Mariners will also benefit by watching the following videos: Duties of the SAR mission coordinator: https://youtu.be/9J3q6XczIGE Duties of the on-scene...

Ships don't exactly have brakes. Lou Vest, a retired Houston ship channel pilot tells us about a close encounter between a ship and a barge.

The International Maritime Organization’s (IMO) upcoming amendments to SOLAS Chapter V, Regulation 23, represent a significant step forward in enhancing the safety of pilot ladder operations.

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...

Apparently there were two crew members on board, but no pilot. One of crew was recovered and declared dead, another one, skipper of the boat, is missing.

As the container shipping industry continues to boom, companies are adopting new technologies to move cargo faster and shifting to crewless ships. But it’s not all been smooth sailing and the future will see fewer players stay above water.
