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.

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

"This is a Lakes Pilot hopping off the Huron Belle Pilot boat after we've pulled alongside the CSL Assiniboine on the Detroit River just above the Ambassador Bridge in Detroit, MI
He walks along the side of the Pilot boat, holding onto the railing and then after the gangway from the ship is lowered into position, he steps up and pulls himself up to then begin walking up the gangway to the deck where he is greeted by the crew.
We then see one of the crew from the Pilot boat tieing up the...
