How does GPS work?

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.

Matthias Meyer was head of the Bremerhaven port pilots, nautical expert and lecturer at maritime schools. In front of our camera, he voices what has long been a topic of discussion in shipping circles: that the 400-meter container ships have simply become too big for the narrow shipping channels of the Weser and Elbe. In his view, a serious accident is only a matter of time. We take a look at how the district is dealing with these giants and what politicians, BUND and shipowners have to say...

With ships as large as 175 feet wide and a channel a maximum of 500 feet wide, how to you safely pass? Former Houston ship channel pilot, Lou Vest, explains how ships fight against hydrodynamics to pass with such narrow margins.

Another video by Knud Benedict: This movie reveals some practical insight into regions of course stable / unstable conditions under wind. And I dare to say you can get some insight into other stability types and analogies, too!

Marine pilot

The Port of Townsville, northern Australia’s largest multi-cargo port, is expanding its fleet of pilot boats to four.

The Port has awarded Hart Marine a $3 million contract to build a 17.3m ORC vessel that is due for delivery later in 2020. The new high-tech vessel will be slightly longer but have the same design features as the PV Osprey which was delivered by Hart Marine in late 2017.
