Faudra que je ressorte le matériel adapté et que j’installe dump1090 sur mon SteamDeck pour tester en extérieur :)
Faudra que je ressorte le matériel adapté et que j’installe dump1090 sur mon SteamDeck pour tester en extérieur :)
Attached: 1 image Dommage que la batterie de mon laptop soit HS, j'aurais bien testé en extérieur (surtout dans un endroit bien dégagé).
I did a fresh install of #dump1090 yesterday on one of my #ArchLinux PCs.
There is an improved version in the AUR, but it didn't compile, so I made some small changes by hand.
It is amazing what distances you can cover with a small passive TV antenna and a ~10y old TV stick...
Reloaded card with latest OS
Reloaded dump1090-fa
Reloaded all the various sundry feeder scripts
Loaded log2ram in an attempt to minimize writes to card, so I don't have to keep doing this.
I MUST NOT WRITE. WRITES ARE THE SD-CARD-KILLER. WRITES ARE THE LITTLE-DEATH THAT BRINGS TOTAL CARD OBLITERATION. I WILL CACHE MY WRITES. I WILL PERMIT WRITES TO REMAIN IN MEMORY AND THROUGH ME. AND WHEN THE DATA HAS GONE PAST I WILL FLUSH THE DATA INTO THE ETHER. WHERE THE WRITES HAVE GONE THERE WILL BE NOTHING. ONLY STATIC DATA WILL REMAIN.
Now I've got a really really simple 1090 MHz vertical sleeve dipole. Ho. Ho. Ho.
Signal according to dump1090: -19.5 dB, peak -1.1 (total of approx. 30 mins)
I wrote a little program to read ADS-B data from dump1090-fa port 30003 and check if any aircraft nearby get within 0.75 NM and 750 feet of each other, and yes, it happens frequently.
The most alarming is KBUR passenger jets flying over various students in the pattern at KVNY.
These two had 725 feet and 0.696 NM of separation:
