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.

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.

A unique 3D video endeavoring to raise the awareness of the seafarers about a very important, critical, and essential piece of equipment on board. Basic in design, but high on purpose, the mistakes incorrect handling of this equipment continue to result in Near Miss, Incidents and accidents.

Another great education video by Knud Benedict (Germany): Practical experiments for getting useful data for planning.

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

This video provides the detailed explanation of the phenomenon showed in Part 1 of this topic and a solution for this problem at the end. This phenomenon was recently disocovered by Dr. Steve Shaojie Tang and published in his book by Faiteve inc in 2018.

Join us out in the North Sea as we take on another challenging day aboard the pilot boat, transferring pilots to and from massive ships in choppy seas. 🌊 Watch as we battle the swell and spray, timing every approach perfectly to safely board and disembark pilots onto moving vessels in tough conditions. From cargo ships to car carriers, this video gives you a front-row seat to life at sea — where precision, teamwork, and nerves of steel are essential. 📍 Filmed off the North East Coast of...

Primeiro teste da nova profundidade do canal de Vitória (ES). Os práticos Evandro Oliveira Daquino e Rafael Amorim Sobreira realizaram a manobra de saída de navio com 11 metros de calado. Ambos participaram do estudo prévio realizado no Tanque de Provas Numérico da USP. O prático Fabio Andrade Batista dos Santos também esteve presente na faina, sem ônus, como avaliador. Ele fez todos os registros da manobra, como a menor profundidade medida ao longo do canal etc.
