Possible Dump1090 Enhancement?


#1

when i run two receivers on the same antenna i most often get more aircrafts when both streams are combined. i leveled both receivers not perfect but really pretty well - and of course there are differences in the sdr-dongles as well as in the incoming signals.

but because the pi2 and pi3 are multicore computers couldn’t be there a slight improvement if two instances of dump1090 would examine the same incoming data-stream from a single dongle - and this way together find more messages/aircrafts than one instance?

cheers

No. The demodulator is deterministic.

ok - understand - that means same input would always produce exact same output?!
this way it would only make sense if the demodulator algorithm were slightly different - maybe both biased into slightly different directions. but then the question is what improvement would result from what effort …
