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.

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.

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.

What happens when next-generation maritime data is put to the test in some of the most complex navigational environments? This video shares insights from a major international S-100 simulator trial, delivered in collaboration with Carnival Corporation’s CSMART training facility and a wide network of global partners. Together, we explored how S-100 data sets perform in realistic, high-pressure bridge scenarios—particularly in confined waters where precision and timing are critical. Bringing...
