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.

This updated video shows how easy it is to develop an arrival plan with the SAMMON Planning Tool. As a sample the arrival from appraoch until the berth to Ft. Lauderdale is used under strong current of 2kn. At the simulator training courses where we used this tool for preparation of a manoeuvring plan during the briefing sessions all nautical officers involved stated afterwards: "Why don't we have this tool on our ships?"
