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 explores the question of why ships are so difficult to manoeuvre in reverse.

Case Study: An investigation into whether Port of Melbourne and major port user, ExxonMobil, could bring deeper drafted vessels into the channel.

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...

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.
