Article GPS (Part 2), physical and technical errors of GNSS - an error analysis
by Capt. Gunter Schütze, Thailand/Germany - published on 26 February 2020
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,

Video Spiral-Test -Manoeuvre for detailed identification of Yaw Stability using Samples of Cruise Ship
published on 29 September 2021
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.
Article A review of the ship’s pivot point: Science, Maths and Observation’ Where is the centre of a ship’s rotation?
by Tim Cummins, Harbour Pilot, Portsmouth International Port - published on 17 July 2020
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.
