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.

Maneuvering ships are complex operations with high-risk involved. Just like nautical projects, they need to be simulated on training centers before approved. In a scenario of growing ships and limited waterways, state-of-the-art technology is essential to safely increase ports efficiency. That is why Brazilian Pilotage brought the most modern bridge simulator next to the maritime regulatory entities. Located a few minutes from government agencies, in the brazilian capital, our training...

Here’s a cool little video of the rough weather sea trails of ‘Port Láirge’ The Port of Waterford’s new Interceptor 48 pilot boat ready to be delivered next week. We had two days of rough weather, a Force 8 with 3.5m seas putting up some surf breakers over the Daunt and a second day with winds reaching Force 10 offshore, with 55kts of wind and 5m swells, allowing us to properly test her capabilities ensuring she's fully fit for purpose for the pilots and crew. Doing so we captured some...
