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.

Many people wonder how ships made it across entire oceans without getting lost in the seventeenth century. Aaron introduces seventeenth century navigation to us today by beginning with piloting.

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!

To minimize the risk of a vessel allision with a terminal gantry crane, the American Harbor and Docking Pilots Association recommends that all terminal operators with gantry cranes adopt the following Best Practices.

On the occasion of the Maritime Safety Week (July 4-10), UK MAIB’s inspector Bill Evans refers to the issue of unsafe pilot ladders, a concern that has been regularly voiced by the industry.

A story I shot on the Delaware river pilots, very cool people who have a very important job. Every cargo ship that has to get anywhere up the Delaware River gets a pilot delivered to it while in the Delaware Bay, who guides it up through the narrow shoals

Ships have reported an increasing number of cases of significant GPS interference and jamming in recent months. The geographic areas with more than one reported incident include the eastern and central Mediterranean Sea, the Persian Gulf, and multiple Chinese ports.
