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.

Maritime pilots trace the roots of their profession back to the ancient Greeks and Romans when incoming ship captains employed experienced local fisherman to guide their merchant vessels safely into port. It’s a legacy of skill, strength, and sharp wits, and our Houston Pilots (“Pilots”) have been meeting vessels at Galveston’s bar to carry on these proud traditions for just shy of 100 years.

MARIN has done model tests with a model of the msc Zoe in one of its test facilities, to find out what caused the msc Zoe to lose containers and how we can prevent this in the future.

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!

Conapra's Technical Director, the pilot Porthos Lima, presented during the 53rd EMPA GENERAL MEETING the application developed for smartphones, inspired by the 2017 IMPA SECURITY CAMPAIGN. This tool allows pilots to report deficiencies in the Pilot Packing Arrangements and ship equipment, and these reports are instantly available to all Brazilian pilots. In the presentation Mr. Lima, representative of the Brazilian Maritime Pilots Association, showed how the App works and presented its...
