by Capt. Santosha K. Nayak - published on 18 November 2020
Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses.

Lack of standard user interfaces across bridge equipment is a major concern for maritime safety. Pilots are in a unique position, as they are constantly exposed to new and differing bridge working environments, equipment, interface designs and combinations of systems. As pilots face this problem throughout every shift they need to put in considerable effort to adjust their work to the many user interfaces they meet.
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,
