How GPS works? Trilateration explained

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.

Two new locks were introduced in 2009 for training in the new Panama lock conditions with or without tug(s). This video shows the famous "piston effect" when entering the lock at an impressive speed of 10 knots with a high blockage factor.

Serkan Kahraman and Yusuf Zorba have published a new book for marine pilots. In this book, maritime pilots and shipmasters’ situational awareness levels have been analyzed using a bridge simulator system and the results have been obtained.

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.

Improvements to pilots’ situation awareness (SA) in maritime navigation are critical to reducing human errors, which have caused 75% to 96% of marine accidents over the last few years.

In our new new section “Five questions for ..." Marine-Pilots.com introduces pilots and other market players to our readers in short interviews.

Today we have talked to Olli Taipale, Chief Pilot at Finnpilot.
