Ah a fellow perun addict.
Honestly I think he oversold the effectiveness of the systems. The work I did is still ongoing so I’m up to speed on the available systems, though mostly on the RF side. If you watch the stuff coming out of Ukraine the drones aren’t really being impeded all that much and if you know how to use ardupilot and selectively enable your data link you can pretty much get away with whatever you want because the US isn’t gonna allow anyone to jam GPS right next to multiple major airports. If you want to avoid even relying on GPS there are starting to be mature solutions out there too.
Interesting, I haven’t heard about that.
For systems that…may experience some degree of vacuum…it’s common to use lead solder still because it doesn’t tin whisker so unfortunately it’s still around for some of the stuff I’ve worked on.
