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.

This video shows an introduction on the Pull-out Test-Manoeuvre and describes the procedure how to steer through this simple manoeuvre: Turning circle and then put the rudder amidships. The final rate of turn allows to identify stable and unstable conditions.

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

Don't have time to edit hehe apologiesssss

GNSS interference has become a growing challenge in the Baltic Sea, affecting maritime navigation, aviation, and critical infrastructure. While numerous datasets and services, such as gpsjam.org, spoofing.skai-data-services.com, and flightradar24, report high-altitude GNSS interference based on ADS-B data, there is a significant lack of studies focusing on ground-level interference.
