what are you using to see to map output from DUMP1090?
I have to following installed and running;
DUMP1090 FA
DUMP978 FA
TAR1090
3D Maps
Programs install onto my Pi feeder
MODESMIXER2
VRS
Both these feeder programs are sharing a common directory called data which contain a basestation.sqb, Flightroute.sqb. Logo folder and a silhouttes folder.
I do notice by using a basestation.sqb file I get better information about the aircraft.
VRS with my own basestation.sqb, but I have it on my Windows PC, not running all the time on the Pi.
For the .SQB, install the VRS plugin, and let it run over a period of time to build it up. If you are a member of ADS-B Exchange, get a feed from them and buid the “mother of all .SQB”.
That’s not available at the moment, due to people using the data commercially without giving something back.
Obivously that’s a hot topic over at the forums.
