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.

This video provides the detailed explanation of the phenomenon showed in Part 1 of this topic and a solution for this problem at the end. This phenomenon was recently disocovered by Dr. Steve Shaojie Tang and published in his book by Faiteve inc in 2018.

This my attempt to do just that. This is a summary of all scientific papers and articles that I could find about the ship’s pivot point. I have added links to any videos associated with the publications and have also included any useful diagrams or equations that the authors published to help explain their research.

At Humber Maritime College we have state-of-the-art marine simulators to teach our Merchant Navy cadets in an environment close to reality, preparing them for a career at sea.

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

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...

In this paper, the risk of ship pilotage in Jiangsu section of the Yangtze River is studied by fuzzy comprehensive evaluation: risk factor identification, risk evaluation and decision making suggestion.
