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.

Project results in detail. Efficient port flow using the Port Activity App in the ports of Gävle and Rauma. Sharing time stamps making planning easier for all involved actors. Efficient ship Flow by using a Route distribution service helping pilots better plan meeting points in narrow fairways, saving some fuel but more importantly increasing safety.

Another great education video by Knud Benedict (Germany): Practical experiments for getting useful data for planning.

A unique 3D video endeavoring to raise the awareness of the seafarers about a very important, critical, and essential piece of equipment on board. Basic in design, but high on purpose, the mistakes incorrect handling of this equipment continue to result in Near Miss, Incidents and accidents.

Coast Guard air and surface rescue crews at Sector San Juan responded and assisted the distressed M/V Island Express Wednesday afternoon, after the ship started taking on water when it departed the Port of San Juan for storm avoidance in anticipation of Tropical Cyclone 9.
