Sometimes you run into a very oooh, shiny! subject when looking for something else. I visited David Taylor's pages looking for his writeup of FreeBSD NTP server with an external GPS mainly to 'compare notes' with my own FreeBSD ntpd PPS setup (PPS slave) writeup. No surprises there, but one click led to the other, when I found out that David Taylor is also interested in receiving weather information and dove into that. He has a nice overview of his experiments in weather satellite receiving and decoding and I found out about EUMETCast data where you can receive weather satellite images via a satellite dish. Which uses a 'data' PID on a transponder, which is implemented as multicast data streams. Several personal interests for me and work-related stuff comes together in this. It's good to know this exists, but I won't be running out to buy a satellite weather map receiver now.
