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.

Through the years, the Dutch Pilots have developed a system of selection, initial education and continual professional training. What is the current state of affairs?

Briese research are extending their cooperation with Nautitec for their research training projects. As from immediate effect, a model of the research vessel “Maria S. Merian” can be used for tailor made training at NAUTITEC´s Leer-based simulator facilities.

Educational and descriptive video

Kongsberg Digital has signed a contract with the Panama Canal Authority (ACP) to upgrade and extend the K-Sim Navigation simulators based in SIDMAR; the Center for Simulation, Research and Maritime Development of the Panama Canal Authority.

Between 2005 and 2018, the TSB received reports of 26 girding situations resulting in 21 capsizings. Girding occurs when a vessel is pulled broadside by a towline force and is unable to manoeuver out of this position. The TSB created this video to illustrate the factors leading to girding and the recovery methods.
The TSB would like to thank Ledcor Resources and Transportation Inc. for use of simulator training images in the girding video. We would also like to acknowledge the U.S....
