Is there an open version for ship data as well?

    Great! They don't seem to have historic ship positions though.. hm.

      It seems like none of the AIS providers store historic ship positions, you probably have to do it yourself if you want that information

  It seems possible to make AIS receiver using RTL-SDR + RPI. I am about to make it, there's a couple of guides online.

    AIS isn’t long range though. You’d need an incredible amount of base stations for any sort of decent coverage of frequented areas.

      50k radius if not more off a 10 sailboat mast. In context of sailing boat that you only meed couple of kilometers. BTW new Iridiums are capturing AIS and ADS-B from satelite.

  Last I checked there AISHub was the biggest reusable source of AIS data. Coverage map here: http://www.aishub.net/coverage http://www.aishub.net/coverage. They are used by various sites like https://www.vesselfinder.com/ https://www.vesselfinder.com/ MarineTraffic has a more comprehensive monitoring network but they keep the data to themselves. Details at https://www.marinetraffic.com/en/p/expand-coverage https://www.marinetraffic.com/en/p/expand-coverage As noted by another comment, AIS signals are being broadcast line-of-sight from the ground so you need more receivers than you do to track airplanes. OTOH you only need the receivers on the coastlines and on major inland waterways, not over the whole earth's surface. (If you want to track a ship mid-ocean, you'll need a satellite. Those exist but cost $$.)
