Dump1090 question

[airbus340]

I read in another forum that Dump1090 now got the same features as the version for Linux, so I installed the Windows version on my PC.

So now I have the --phase-enhance and --oversample. But I also copied the other stuff from my older version, including --aggressive.

With the new version I get about 25nm better range and double message rate but I also get a lot of ghost planes from all strange countries. I never got this problem in the old Dump1090 version.

When I remove --aggressive I dont get the ghost planes but I would like to have the extra range and messages I get with -aggressive. Is there anything I can do to get rid of the ghosts and still use -aggressive or is the only way to remove it?

I really would not recommend using --aggressive at all!

You will always get the ghost planes with that!

 

[airbus340]

Thank you very much Lee! I get a little less than 1 million messages per day so it is fun if there is something that will make it better, but all the ghosts are a pain, so I won´t use --aggressive then.

 

[Lee Armstrong]

No problem,

I wouldn't use any of the "corrective" measures in Dump1090 as the data that largely gets through is spurious.

 

[airbus340]

Do you mean the --oversample and --phase enhance?

 

[Lee Armstrong]

I think you might be ok with those

 

[airbus340]

Ok, what do you mean with the corrective measures then? Something I can change or remove in Dump1090 for windows to get as little ghosts as possible?
With the new version I often see planes at high levels that say GND...

Sorry, english isnt my first language...

 

[Lee Armstrong]

No, Dump1090 with certain settings will try and correct some of the data. The usually ends up being wrong!

 

[airbus340]

Here is what I have in my Dump1090, should I add something or remove something?

dump1090.exe --interactive --net --net-ro-port 30002 --net-beast --ppm 94 --mlat --modeac --gain 36.4 --enable-agc --oversample --net --phase-enhance

That looks ok, I don't use Dump1090 a lot though as the RTL dongles don't perform as well as dedicated ADS-B receivers that we use!

 

[airbus340]

Ok, thank you Lee! What kind of receiver do you use? I am thinking about upgrading too, thinking of Airspy or Radarcape. I read that Airspy is a lot better than the RTL dongles and they arent that expensive. Radarcape is the king of ADS-B receivers and very expensive and it might be overkill for a indoor antenna...

I also read that the RTL dongle is more sensitive than Airnav Radarbox and Kinetics SBS-1 so it is difficult to know which one to buy.

I use a mixture but of the ones currently on sale I would go for a Kinetic Puck. By far the best performance/reliability and we use a lot of them here.

I wou;don't use an AirSpy as they use a lot of host CPU resources from experience.

Thanks Lee, I will order a Puck this fall and try it. I haven´t seen many reviews about it but them I have seen say it is pretty good.
