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.

The Arctic magnetic pole does not move anymore. It runs, faster and faster. In recent years, even faster than expected. Therefore, geo-researchers have now had an unscheduled change to their world model and adjust their calculations, so that navigation with compass and other navigation aids such as a Pilot Plug, used by pilots around the world, continue to work.

Version from 1st May 2021: Ships that require the services of a pilot need to ensure that the Pilot Transfer Arrangements (PTA) they provide are in compliance with the requirements prescribed under SOLAS V/23 and IMO Resolution A.1045(27) [as amended by IMO Resolution A.1108(29)].

This article describes the findings from two studies that utilised an integrated systems thinking framework to understand how pilots make decisions and what factors are perceived to influence their decisions.

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.
