Do you need anybody in the US? I'm a senior marine engineer, working on my masters in CS. I'm interested in larger UUV's and USV's in general.

Most of our software roles (one of the biggest teams we're growing at the moment) are located in the U.S.! We'd be very interested to hear from you.

OK, interesting, I'll reach out and inquire. Thanks

Balloons, maybe.

Apart from wind moving it to the side, it would not be a fundamental problem to fly a tethered blimp with a pair of single mode fiber and a thin aluminum wire that is driven in resonance [0] with the surface capacitance the blimp has, relative to earth, up to about 20-50 km. The breaking length of the fiber comes out at ~120 km, and you have to spare some tensile strength to hold the aluminum wire. This is not hard,…

Lightning + aluminium wire is a problem. I suspect an electrical current will form in the wire even w/o lightning because of static electricity. Also the wire is a hazard if it breaks and falls down. It will probably cut everything in its path.

Totally off topic aside: I’m seeing a lot of Bloomberg links these days and I’m constantly “over the free limit.” Sometimes the “web” strategy works, and sometimes it doesn’t (like this article for me). If I add up all the sources that are typical for HN it’s quite a lot. Bloomberg alone is $40/Mo now long term, plus nytimes, Washington Post, economist, FT, etc. I already pay for two of these — I don’t feel the need…

I work for a company that builds boats for many of the same goals in a more traditional form factor. The potential of autonomous marine vehicles is very high, and a very exciting field to be working in. https://www.asvglobal.com/ (If you're interested, we're hiring!)

How do your vessels comply with the international collision regulations? In particular, the requirement to 'at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions'?

I'm so jelly! ("jealous") I've been (slowly and painfully) working my ways towards constructing a self-reproducing robo-boat swarm for a few years now, ever since learning about the Great Pacific Garbage Patch. My idea is to set up a simple artificial ecosystem of interacting bots that collect and recycle oceanic trash to create more of themselves. This permits exponential growth, making it realistic to attempt to ta…

You get an upvote for the sheer audacity of this project. Hope you make good progress, good luck.

There's more then one way to skin a cat, but none of them work 100% of the time for paywalls

ASV global is an amazing company to work for.

A unique and very special group of people. I cannot recommend the place highly enough.

It seems on-board amenities exactly what's being talked about (and, yes, arguably over-simplified) here. Or are you making a distinction between luxuries and basic living conditions (space, privacy, quality/healthfulness of food)? For some people, no level of internet access would make hot-bunking tolerable.

> "For some people, no level of internet access would make hot-bunking tolerable." Completely agree. But in this case, those are not the ppl you want working for / with you anyway.

Why would that trade-off make someone an undesireable employee/colleage to you?

Was the problem with my choice of the Internet (which could be used for work) for my scenario instead of tv channel choice?

If you care about speed aprs isn't your boat. 1200bps in almost all cases, zero FEC, bandwidth rapidly disappears depending on how many digipeaters overlap. It's good for brief beacon based things but most of the RF tech around it is still stuck in the 80s.

Absolutely agree... but an aprs2 that incorporates some modern tech and modern thought could be interesting. What if every TNC was also a digipeater and they all coordinated to route their traffic via the shortest/best route to shore?

BTW: this conversation has convinced me to buy a LimeSDR Mini. It can handle Marine VHF, (probably AIS with a GPS source) and even LTE. I figure having a couple of these might be great on a boat since you can reuse them for a variety of purposes and having backups are key. They even fly LimeSDRs on micro satellites.

As it happens my full-time job is working on our COLREGS path planning and collision avoidance :) Our primary focus at the moment are the rules concerning standing on/giving way with respect to other vessels. Some of the other rules, such as the one you mention, aren't being handled at the moment. However, we do have active projects working on the vision side of things to help get us closer to full compliance.
