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.

With the increasing accuracy and reliability of navigational receivers, this part of the video module will try to establish a better understanding of the mathematical definition of the Earth’s surface and mapping of this curved shape onto a plane surface.

In this webinar, Rev. David Reid, AFNI looks at why we need to learn this skill and put it to work to promote safety at sea and the wellbeing of our colleagues. Are we mind full or mindful?

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.

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

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.

Flying from Shortlands, following the beautiful HM Orc 181 "Nepean" Flying to the very edge of VLOS helped by the elevated position in the carpark, also helped by a good strong coffee from Hesse St! Little known fact, when I was a small child I went out in the Pilot boat from (dad recalls) Gem Pier in Williamstown! I only remember being a bit scared and that's about it.

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 are happy to start with Capt. Ahmed Sati, Marine Pilot at P&O Maritime.
