> we have received and processed ADS-B signals collected by our autonomous boat... I wish the article would've explained: (1) What is ADS-B, and (2) why does it matter. Without that context, I have no idea if this is significant or not... EDIT: Given FlightRadar's business... I'm guessing it helps with flight tracking. This wasn't entirely apparent from an outsider reading that blog for the first time.

Aircraft broadcast ADS-B signals which contain tracking information, which is used by live flight trackers to map out each flight in real-time. The problem is that there are large blind spots when aircraft go over oceans due to the lack of receivers, so this is intended to increase coverage.

ADS-B signals (from my limited knowledge) are transmitted by aircraft showing some basic data like location, altitude, speed, callsign, aircraft model and a few other things. They only have a range of a few hundred kilometers so a website that does flight tracking using a global network of (volunteer) receivers, it's a step in their coverage to be picking up signals over the oceans. Also it's just cool.

Good info on ADS-B https://www.renderlab.net/projects/ADS-B/ https://www.renderlab.net/projects/ADS-B/ Also just google "Defcon ads-b", there are a few.

You can track planes over you with free software and a small homemade antenna: Free software: https://github.com/antirez/dump1090 https://github.com/antirez/dump1090 Inexpensive antenna: http://antirez.com/news/46 http://antirez.com/news/46

It's an industry specific, aviation, app. Chances are, if you are there you have a glancing familiarity with what it means and how it works. If you didn't know and were interested 2 minutes on Wikipedia would have you sorted out. Unless writers are getting paid per word most computer blogs aren't defining CPU, GPU, USB, HDMI for their readers.
