It seems they have AIS (traffic) integrated among others. I have also seen integration with older radomes as part of the <a href=\"https:\/\/github.com\/opencpn-radar-pi\/radar_pi\">radarpi<\/a> project. <\/p>\n\n\n\n<p>The industry standard for networking devices together is NMEA2000, which is a protocol far too slow for radar data, but seems to work well for things like wind speed, gps position, depth, etc.<\/p>\n\n\n\n<p><a href=\"http:\/\/signalk.org\/index.html\">Signal K<\/a> is an open source project for integration of NMEA2000 stuff into the PC. From what I&#8217;ve seen so far, they&#8217;ve put a lot of work into it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Ultimate:<\/h2>\n\n\n\n<p>A PC connecting to the boat&#8217;s WiFi network that connects to a server (perhaps running on a Raspberry Pi) that talks to boat systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related links:<\/h2>\n\n\n\n<p><a href=\"https:\/\/github.com\/rseal\/GnuRadar\">GnuRadar<\/a>: Need to explore<\/p>\n\n\n\n<p><a href=\"https:\/\/www.cruisersforum.com\/forums\/f121\/digital-radar-without-the-proprietary-display-80022.html\">Cruiser&#8217;s Forum<\/a>: Post about someone wanting to do the same, but dated.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.si-tex.com\/item\/mds8radarsensor\">SI-TEX MDS 8R<\/a> was (is?) a Radome that plugged into a PC&#8217;s ethernet port. Interesting, not sure if it continues to be in production.<\/p>\n\n\n\n<p>After more research, it seems radar is going the ethernet route. More of them are going headless, and I am hopeful that standardization is coming soon.<\/p>\n\n\n\n<p>Update 16-September-2020<\/p>\n\n\n\n<p>radar_pi has done a lot of work on this already. It seems the tight grip that manufacturers have on their hardware limits (but does not eliminate) the usefulness of writing such code.<\/p>\n\n\n\n<p>Manufacturers do sell the antenna separately from their head units. Whether a setup replacing their head unit with a generic one would cause things like voided warranties have yet to be seen.<\/p>\n\n\n\n<p>To truly reverse engineer, build, and test such software would require the actual hardware. <a href=\"https:\/\/github.com\/opencpn-radar-pi\/radar_pi\/issues\/116\">This post<\/a> talks about someone working on such a thing with Furuno hardware.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I am researching open-source projects for marine weather radar.
