Nice range! Even though your radar code may mother show, the data is still being used. Nice to see another nearby feeder.

Watch for this tanker to fly to New South Wales, Australia in about 2 weeks. It's equipped with ADS-B.
Let's see what tanker number it will fly under in Australia.
Coulson’s L-382G awarded contract in Australia
Tanker 132 N405LC is due to start there on September 1

[QUOTE=rodeo;69629]Hmmm ... looks like T-YSSY51 and/or FR24 may be having some issues possibly, tonight ...
It is reporting SSM1 (7CF7CA) with wierd altitudes, no squawk code, varying speeds etc - I'm seeing it as its normal rock steady self. Usually the SSMs don't show on the map.
T-YSSY51 is one of several that of late appears to be supplying both ADS-B and M-LAT data for the same aircraft. It also sometimes shows non-ADS-B equipped Virgin ATRs and Qantaslink Dashs as T-YSSY51 rather than MLATx. There has been some previous discussion in this very thread, particularly from poster bhaal who operates T-YBBN50 near Brisbane.

I'm expecting that I'll rarely be seen as the capturing radar, as I'm a bit swamped with nearby F- feeders, but as I type this, I've managed to get a C172 tracked in my name!

??? what call sign, some Virgin ATR's are ADSB equipped, eg: FVU, an ATR-500, is on my screen now

FVU and VPJ are the only two Virgin ATRs that appear to really have ADS-B. If you use the criteria that an ADS-B equipped plane will show as being detected by a particular FR24 feeder rather than MLAT there are others that appear to have it but don't. Similarly, there are only about 7 or 8 Qantas Dashs that have ADS-B - all of them Q400s - but others, and also some Q300s, have started showing up recently.
I gave up on FR24's mlat a long time ago, despite Mike thinking its the bees knees, its far from accurate, so nothing an mlat feed says would surprise me. I'd only question it if its a regular thing, but even then its waste of time, fr24's code system is buggy, they know it despite their denials on many fronts, its why its pointless complaining, as I think you've seen in several topics.
but mlat is ACCURATE, its more accurate then co-ords from true ads-b! I guess fr24 would likely say this pilot's drunk lol

On the other hand, FA's MLAT which is being done via the PiAware + rtl dongles (by associating mode-s packets received at the same time as ads-b packets across 4 receivers synchronously) is proving to be very accurate, it jumps around maybe 100-300ft at most but most times less, as opposed to fr24's which jumps around 1-2nm at times (or more)... If fr24 bit the bullet and started using the same code base which is part of mutability (assuming the licensing allows them to) then they would have just as many people feeding mode-s and if they also gave us MLAT positions as feedback from the MLAT client just like FA, then there would be a lot of happy campers out there!
As mentioned, I am not participating in fr24 MLAT trials until they change things and I have said that point blank to vinny..T-YBBN50 - Kallangur, QLD, Australia

But at FR24 things must be changing, they refused to use anyone but their own f-feeders for mlat data, now they allow rpi's, wonder if its all linux packages - since dedicated servers have much better resource handling than one of them tiny things. but IMO, FR24 have a few things they need to fix before I bother with that, and attitude is one of them, and I aint talking aircraft attitudes lol... I do know mlat setting on dump1090 is active, its always been active for "elsewhere", fr24 have always AFAIK ignored it, so havnt look into their new way. the old software still works and as they say, if it aint ...... dont .... with it

I believe the source for the FA feeder is on github and probably would compile for the A10 or whatever SoC is on the Banana, but it's time that you probably don't have.. As for "their loss" well, my understanding is the PiAware MLAT stuff is the test bed, basically because it's pretty well known what is running, Pi, dongle, dump1090 ... With nothing exotic or weird CPU requirements .. Once they are happy with MLAT working well based on ADS-B time sync then they will expand it to other platforms as well.. And just wondering.. If you are running Debian (or Ubuntu) on the Banana then there is a good chance it will run the ARMv6 code as well, but I could be wrong with that...

If you want me to have a look at your Banana and see if I cannot get PiAware running let me know (the more coverage the better around me)..T-YBBN50 - Kallangur, QLD, Australia
