ModeSDeco2 vs. Dump1090 ?

[Radio2.0]

Was is different between ModeSDeco2 and Dump1090 ?

[IanH]

Repeating my response from the chatbox here:

Both input signal from a dongle and send it to display software. dump1090 provides data to PlanePlotter that can be used for MLAT, modesdeco is more flexible - it can convert formats and has its own display.

Try them out - they are both free.

In response, "Triple7" added:

and according to this http://radarspotting.com/forum/index.php/topic,2978.msg15352.html#msg15352 ModeSDeco also provides data for mlat in PP

I use VRS to collet Data.
I also use other Software for SDR and i know that different Software have a different Signal recognition.
Some Software give me 50% more Data from an Life Audio Feed that the other.
So maybe one of the Application use an better logic behind to give more results.

I've had dump1090 working on my POE RasPi for several months and thought I'd give modesdeco a try. It worked first time! Yay!
Ran top just to check it and it was running the cpu at 40-50%!
dump1090 runs at 10-13% and seems to have the same functionality.

The modesdeco command:
modesdeco2 --gain 40.6 --beast 30010 &

the dump1090 command:
dump1090 --device-index 0 --raw --net --net-bind-address 127.0.0.1 --net-ro-port 30010 --quiet &

the modesmixer command (for use with globe-S):
modesmixer2 --location 35.137:-89.984 --inConnect 127.0.0.1:30010 --globes 31001:table2:EES --web 8080 &

What benefit does modesdeco2 have over dump1090?

Since you are using GlobeS as your display, probably not a lot of advantage since you need to run ModeSmixer2 as well in both cases.

But if you were using some of the options available from modeSdeco2 (such as output to port 10001 for BaseStation software) which avoids the need for modeSmixer2, there may be advantages. Or the ability to use a basestation.sqb file to identify the aircraft in the webserver (dump1090 does not seem to have this capability).

Personally I use dump1090-mutability from my (Orange) Pi since I am sending data to FlightAware via Piaware and that defines the software requirements.

I also use dump1090 on my Windows tablet when away from home - possibly because of the lower CPU usage (not sure I ever did a comparison!).

On a mains-powered device with no restrictions, I would choose whatever I preferred.
