There is a system of AIS to broadcast position, course and speed of marine vessels. Perhaps one could combine this with a mesh relay network to forward packets to boats in the direction of land. An AIS and long range WiFi-like system running on top of sailor’s masts would be a fun community to bring together. Software defined radios could come in handy to handle multiple frequencies and protocols.

- vvanders 8y agoIf 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.
- F00Fbug 8y agoAbsolutely 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?
- state_less 8y agoBTW: 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.
