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.

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills.

AIS services are offered by, for example:

A unique 3D video endeavoring to raise the awareness of the seafarers about a very important, critical, and essential piece of equipment on board. Basic in design, but high on purpose, the mistakes incorrect handling of this equipment continue to result in Near Miss, Incidents and accidents.

Version from 1st May 2021: Ships that require the services of a pilot need to ensure that the Pilot Transfer Arrangements (PTA) they provide are in compliance with the requirements prescribed under SOLAS V/23 and IMO Resolution A.1045(27) [as amended by IMO Resolution A.1108(29)].

In December 2022, a week-long innovation camp was organized in Turku Finland, in which 16 students from the University of Turku, Novia University of Applied Sciences and five different universities in Singapore participated. Pilotage operators Finnpilot from Finland and PSA Marine from Singapore acted as industry partners.

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...

I decided to show the typical happenings when a saltwater freighter arrives Duluth. Most of the time they go to anchor and wait for the Elevator dock. The Pilot Boat brings out the Great Lakes Pilot to sail the ship into the port and to the dock. This vessel arrived early Sunday morning, went to anchor until mid afternoon. They are loading grain at the CHS Elevator in Superor.
