Dandy article for anybody with a general interest in modern #MaritimeNavigation. The backgrounding sections are a true treat.

For a #SalishSea fleet I work with we've inserted geofencing to avoid interfering with #orca pods. #GPS data collected from #NMEA bus fed into a flea-sized #MCU running with a small database and a simple alorithm driving audio/visual alert suffices for vessels without native #MFD capacity for this. Crude but effective. :-)

NatureTheoretical research and system design of ship navigation guidance for local temporary prohibited navigation area - Scientific ReportsWith the continuous advancement of intelligent technology, intelligent transportation has become a prominent area of research within the transportation sector. In contrast to road-based intelligent transportation systems, the development of intelligent maritime transportation remains in its early stages. This paper proposes a foundational theory and related concepts for ship navigation guidance to address the gap in theoretical support for intelligent maritime transportation. By examining both individual and system-level attributes, the similarities and differences between vehicles and ships are analyzed. Drawing on the theoretical framework of road-based intelligent transportation and the unique characteristics of maritime transportation, the paper introduces the core theory of intelligent maritime transportation, specifically the theoretical structure of a ship’s intelligent guidance system. Based on this theoretical framework, a prototype of the ship navigation intelligent guidance system was developed and tested. The experimental results demonstrate that the system successfully integrates core technologies, each fulfilling its intended role. The system significantly enhances the safety of ship navigation and fosters the advancement of intelligent maritime transportation. Therefore, the proposed definition of ship navigation guidance and the associated technical framework for the intelligent guidance system not only enrich the theoretical foundations of intelligent maritime transportation but also offer valuable insights for the development of intelligent ships.

So, since Windows this morning proved me again how incapable it is to handle my generic boring computer usage, I feel like I at least need to start looking into Linux. I mean maybe I like it, can't know if I never tried. So my question for all the #blind #Linux folks, what's the best way to get started with stuff like #Orca. Please don't flood me with some advanced whatever stuff. I just want to get something running on VMware to try around, to see how it's actually going. Of course I understand that there is a learning curve but I guess I'll need it sooner or later anyways, for whatever might come.

Bonus 4G signal range as we round one of Norway's outer island bits right now just to say that we did see the aurora from our balcony last night but, more spectacularly for us, today we saw an orca surface about fifty metres from our balcony. Anyway, Leknes tomorrow, but a shorter visit than planned to avoid the worst of a strengthening wind. More when we're ashore.

NEW BABY ORCA!!! Only a few days to weeks old.

The orca is the great-great-grandbaby of *one* Orca named Wake who was one of 6 orcas captured by the Vancouver Aquarium in 1976 to be put on display. But after a court battle, they were released, and this *one* Orca is now the matriarch of 6% of the *entire* remaining southern resident Orca population!

Watch the video of the new baby here!

One of my colleagues at the art supply / frame shop I work at, her boyfriend is Haida (an indigenous person of the Pacific Northwest Coast of North America). I love Haida & Tlingit art! So before I retire next week I paid him for a print of this Orca. Today I printed it out & framed it. I'm very happy with how it turned out! He (Alex) is a very talented artist! (Phone photo.)

A nearly square color photo of a stylized ocra whale. The orca is painted in a red-orange and black. It is curved in a crescent shape, as if it jumped out of the water and was diving back in, and pointed toward the left. Its tall dorsal fin is in the center of the image pointing straight up. There are various other images of whale faces painted in the negative space of the body and flippers. The image is framed with an inner border of the same red-orange, then a white mat, and mounted on a black frame.
