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.

🚤 Safety at sea starts with preparation. Our Marine Operations team recently carried out a live Man Overboard (MOB) drill using the new recovery platform on our pilot boat, Trais Leopard. Regular training exercises help ensure our equipment, procedures and crews are ready to respond effectively in an emergency. These drills are a vital part of maintaining the highest standards of marine safety and operational readiness. ⚓ Prepared. Practised. Ready to respond. #MarineSafety #ManOverboard...

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 should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...

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.

I’ve wanted to visit the Warsash Maritime School ship-handling centre since before I ever set foot on a ship. It’s visited by pilots from all over the world for the kind of specialist training, realistic simulations and real-world expertise you rarely get elsewhere.
As a Tug Master, I handle ships by pulling and pushing them around, so to see these intricate manoeuvres using only the ships equipment really fascinated me.
I can’t thank all the instructors, Warsash and Solent uni enough for...

Join Great Lakes maritime historian and antiquarian Brendon Baillod as he discusses the restoration and conservation of a rare and very early 1865 Thompson's Great Lakes Coast Pilot. Early coast pilot books were kept on every schooner and steamer and Lakes and contain important details about the history of harbors, navigation, obstructions and shipwrecks on the Lakes. This 1865 Thompson's is among the rarest and also badly in need of stabilization. Enjoy this two part series where this...

It's quite possibly the most isolated lighthouse in the world and is precariously perched on top of a rock pillar with the wild waves of the cold North Atlantic ocean raging below.
