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.

Port operations, whether these are being performed on water or on land, are often not without risk. Pilots boarding a ship while sailing, navigating through narrow passages, collision avoidance with other smaller or larger vessels, discharging and moving cargo on land, walking between container handling equipment and trucks…

Pilotage is being able to navigate safely into and out of a harbour/anchorage/port knowing where you are at all times, where your hazards are and a safe route in/out. This is particularly useful if you are heading into somewhere new or a challenging/busy area – or both!

During a meeting on 4 December 2024, the International Hydrographic Organization Nautical
Information Provision Work Group (IHO NIPWG) held a vote on the new Guide for Nautical
Data 2.1. The guide was unanimously endorsed.

The Ever Act, the worlds largest and the second to be built out of a series of 12 record breaking vessels prepares to depart Felixstowe Berth 9 with a maximum draught of 10.2 metres for her next port of Hamburg.  As the DFDS ferry was heading inbound at the North Shipwash, Harwich VTS had asked then to make best speed so they planned to get the Suecia Seaways through before the Ever Act broke away. A Harwich Haven Pilot Launch heads over from Harwich with a pilot for the Ever Act....
