Five layers cover the Atlantic facade (²) , from the North Sea and the Shetlands to the Canaries and the Azores, and one layer covers the Greater and Lesser Antilles.

But the most important are the three layers covering the western, central and eastern Mediterranean, which now provide detailed coverage from the Ionian Sea to the Aegean Sea. An excellent complement to the international SHOM layer. Read more →

This evolution is directly linked to the multiplication of satellites communication and positioning means allowing remote control of mobiles at sea.

Even with containment during the Covid-19 pandemic, maritime traffic never stops. Marine Traffic view

Among the many questions - ethical, social, ecological, political - that it can raise, the most immediate concerns the safety of navigation, for trade as for pleasure. Which more specifically involves the International Regulations for Preventing Collisions at Sea, the COLREGS (¹). Read more →

Smart navigation – From paper charts to augmented reality

I relayed here, in French, an article published in the British magazine Yachting Monthly (¹) on April, 30 th. The subject deals with the debate between paper charts and electronic navigation, by stating many truths, but also sometimes one or two untruths. The purpose has the merit of presenting contrasting arguments, and to obtain the opinion of recognized UK's professional boaters. Since the confinement imposes time constraints on us, let's take this opportunity to enjoy this instructive reading.… Read more →

Iridium GO! A positive feedback [Update]

A test several weeks, conducted in October and November 2016 during a transatlantic delivery, had already demonstrated its ability to download GRIB weather files and frontology maps despite the low rate (about 10 KB / mn). With the new Iridium NEXT constellation (¹) we notice since 2019 a real improvement in the global coverage without satellite disconnection.
