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.

An article by Arie Palmers highlights his collaboration with Multraship to develop a solution aimed at enhancing the safety of pilot boarding on harbor tugs, ultimately reducing delays.

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.

Short demonstration highlighting key features of the VR Marine Pilot training simulation LWA Solutions have delivered for the Ports of Auckland.
Editors Note (4th July 2020):
This video shows the fantastic possibilities of virtual reality technology. Wonderful demo by Ports of Auckland. In respect for doing this amazing experiment. If somebody knows more about this or other interesting similar projects please leave a comment below and help us to complete information about virtual reality...

Port Revel is used for shiphandling training of maritime pilots, masters and officers on a 5 ha lake with 11 manned model ships representing 20 vessels, and 4 tugs at scale 1:25 and DGPS tracking system. Instructors are former maritime pilots.
Training on the scale models provides experience that could never be gained on real ships for the simple reason that neither ship-owners nor local authorities would allow such risks to be taken. Scale models allow the shiphandler to make mistakes....

Risk Involved When Unmooring Operation on Deck

Many consider the Bristol Channel pilot cutter to be the finest sailing boat design ever. Fast, seaworthy and beautiful to behold, the pilot cutter is the perfect combination of form and function - a thoroughbred perfectly adapted to a life in one of the Britain's most treacherous stretches of water. Sailor and writer Tom Cunliffe explores the life of the pilots and sails a perfectly restored cutter to find out just what drove these men and their wonderful machines.

Tuco Marine Group has added the new 9,3-meter P-top design to the ProZero series.. The low-weight, semi-open design results in a faster workboat that has a larger operational range and extended working time on sea. The P-top features a protective P-top console solution and flexible seating arrangements which can accommodate up to 12 passengers or a full deck cargo.
