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.

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.

Port Revel is a ship handling training center for pilots, captains and officers. Unique in its kind, it allows to acquire new skills, to improve on different manned models at scale 1 / 25th.

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

The ICS Guide to Helicopter/Ship Operations is the industry standard best practice guide for shipping companies, ships’ crew and helicopter operators.

Captain Reginaldo Pantoja, AFNI: "Now, as a professional harbour pilot for over 29 years, I try to apply the lessons I learned during these times and also when I worked as a mooring master, tow master, and dock master."
