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,

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.

The technology group Wärtsilä will supply a complete navigational simulator upgrade for the Le Havre pilot station in France. The intention is to provide the pilot station with a totally new simulator specifically adapted to the requirements of the pilots’ operations. The order with Wärtsilä was placed in February 2020.The new unique visualisation system to be supplied is based on 14 DP projectors, comprising seven main circular and seven ground projection systems. It features a panoramic 350-degree screen.

The transfer of pilots to and from seagoing vessels should not rely solely on mutual trust and good intentions.
