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.

This paper aims to explore the possibilities of improving team performance on the bridge in pilotage waters. The pilot and the bridge team have a common goal: to navigate the ship safely and smoothly.

Let us see how a maritime pilot is transferred by helicopter to a ship. In this video, we discuss briefly some procedures in a helicopter/ship operation for the transfer of pilots.

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.

Required tug power and number of tugs needed in variable conditions of wind, current and waves isin most cases an assessment made by pilots based on their professional experience. However, assessments will raise questions by lawyers if something goes wrong. They will use tools to calculate what really is needed with respect to tug power and number of tugs. They have furthermore the advantage of time.

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.

Rostock; 02.05.2020: Actually, the special ship with the giant heavy-lift crane crane, which was designed for over 5,000 tons load capacity, was supposed to be delivered in the next few days. During final tests the crane broke off in the afternoon of May 2. Four people were injured in the accident. This is the second accident with Liebherr cranes this year in the Rostock overseas port. Already in February this year two cranes were reported to have fallen into the water during loading....
