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,

Opinion A Corrected Version on Positioning of Pivot Point

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. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.
