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.

Bremen, 24.10.14: How to navigate a ship properly? How do you enter which port? Future captains, but also experienced pilots train in the "Ship Handling Simulator" at Bremen University of Applied Sciences.

To monitor the vessel’s progress, the pilot had set up his portable pilotage unit (PPU). He had connected the rate-of-turn generator to the vessel’s pilot plug and had set a variable range marker on the radar with a radius of 0.5 nm.

As a part of the ISTLAB project the impact of external factors on pilots’ activities in a remote pilotage situation has been examined in Rauma.

The European Tugowners Association in collaboration with the European Maritime Pilots Association has produced this informative video on efficient and safe towage operations. These guidelines address the main factors affecting the safety of harbour towage operations such as good communications between pilots, ship captains and tugmasters.

I have had the privilege of being at quite a number of meetings, conferences and seminars, sometimes representing The Netherlands, but mostly representing the Netherlands pilots. I have had many discussions about the role of pilots and pilot organisations, which lead me to write an article “What is the added value of pilotage?”, published in the February 2020 issue of Seaways.

Following a competitive, international selection process, the Port of London Authority (PLA) has signed a contract with British family-run company, Goodchild Marine Services Ltd, to build a new pilot vessel.
