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.

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.

Maritime pilots trace the roots of their profession back to the ancient Greeks and Romans when incoming ship captains employed experienced local fisherman to guide their merchant vessels safely into port. It’s a legacy of skill, strength, and sharp wits, and our Houston Pilots (“Pilots”) have been meeting vessels at Galveston’s bar to carry on these proud traditions for just shy of 100 years.

Maritime pilots work in an irregular deployment system (rotation system) with unpredictable work assignments under high levels of physical and mental stress. Fatigue or chronic diseases, e.g. coronary heart disease, peptic ulcers or gastritis can occur as a consequence.
