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 movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion.

The purpose of this quantitative, ex post facto study was to assess P-J fit theory by examining the relationship between personality traits, as measured by Jackson’s (1984) PRF-E, and selection for a maritime pilot job.

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...

Fewer vessels in voyage mean less pilotage and this means less income for many Pilots. Not every Pilot is an employee and many pilots are self-employed and organised in a brotherhood per example. They are earning only money if they are piloting a vessel. No vessel – no money.
