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.

What happens when GNSS fails? In maritime navigation, this isn’t a hypothetical scenario – it’s a growing risk. Spoofing, jamming, and GNSS outages are increasing, especially in the Baltic Sea region. A failure can cripple navigation systems – with potentially serious consequences.

This video has already been published for the first time in 2020. Please also note the second, more recent video in the appendix. This physical ladder simulator was designed for crew training in the ladder arrangement and for all the users especially for pilots.

Specialized training for maritime pilots
Quebec City, Quebec, Canada – June 23, 2020 – The Maritime Simulation and Resource Centre (MSRC), a world-class pilot simulation training and port feasibility studies facility, is pleased to announce the release of an informational video on the new S-102 standards on surface bathymetry products.
In the video, Captain Pascal Rhéaume, pilot and member of the technical committee for the Corporation of Lower St-Lawrence Pilots, an active stakeholder...

On the occasion of the Maritime Safety Week (July 4-10), UK MAIB’s inspector Bill Evans refers to the issue of unsafe pilot ladders, a concern that has been regularly voiced by the industry.

On May 11, 2020, in the early morning hours, the news went around the world that two serious marine casualties occurred in sector 8 of Singapore Street within 6 minutes.

This important topic is still underestimated in shipping! Can you trust your GPS? Your Galileo? Knowing where the ship is and where to sail next is the main task of navigating a ship and is commonly supported by using Global Navigation Satellite Systems (GNSS). But what happens if the GNSS gets intentionally disturbed?
