Anyone with specific hardware setups that seem to work well willing to share data flow etc to centralise?
I've added a SBS3 theoretical that needs some verification. And my own beast setup.
DVBT is fairly straight forward. But happy to hear with anyone with working SBS1/1er and micro adsb etc to confirm if as straight forward as I suspectPosts not to be taken as official support representation - Just a helpful uploader who tinkers

Oblivian I have had another go at running my SBS-3 (USB) with the software (T-EGBE12)
In seven days its only crashed once, a big improvement from the daily crashes that we used to get.;-)
Its worth noting that during the install the feeder software thinks my receiver is an SBS-1 and the feeder sees much more data. Most of this data is rubbish, I only noticed this when trying to check on the crash.
AIRCRAFT SEEN: 36,934 POSITIONS REPORTED: 377,078 MAXIMUM DISTANCE: 336nm
AIRCRAFT SEEN: 39,064 POSITIONS REPORTED: 383,128 MAXIMUM DISTANCE: 332nm
After I changed the setting to SBS-3
AIRCRAFT SEEN: 2,243 POSITIONS REPORTED: 315,350 MAXIMUM DISTANCE: 208nm
AIRCRAFT SEEN: 2,283 POSITIONS REPORTED: 325,241 MAXIMUM DISTANCE: 199nm
AIRCRAFT SEEN: 2,461 POSITIONS REPORTED: 342,180 MAXIMUM DISTANCE: 204nm

Hi Folks, about this thread, still work?
MLAT requires 4+ in-range receivers:
- Various combinations of Rpi + FR24 receivers contribute (1FR + 3 Pi, 2FR + 2Pi etc)
- min. 1x FR24 receiver required in combination
- Overlapping FR24 Receiver GPS-time MLAT prioritised
- NTP used for commonreference on RPis alongside FR24 data
- All receivers need to contact the same Mode-S Only aircraft (and 1x ADSB reference aircraft).

But before asking if you will help by adding a GPS receiver like last time - https://forum.flightradar24.com/thre...733#post104733
Nothing has changed there, and adding one will not assist. Only FR24 feeders use GPS. All others are NTP for reference only.Last edited by Oblivian; 2018-10-04, 07:04.Posts not to be taken as official support representation - Just a helpful uploader who tinkers

It may be coincidence (I changed a few things ), but pointing your Pi running fr24feed to a local Stratum 1 NTP server appears to allow it to send more MLAT data to FR24.

"MLAT Seen" is "mlat-number-seen" from the monitor.txt page.
"MLAT Pushed" is "mlat-time-last-push_count".
Around the middle of Week 38 I edited the Pi's /etc/hosts to point all the NTP servers FR24feed uses to the local NTP server.

Your post seems stuck, if I did everything I need to do to contribute. There is a software that changes the data of the airplane's Timestamp at the hardware level, so that they are not used in other competing networks.Last edited by vinicius325; 2021-05-20, 12:17.

Makes no difference whatsoever. NTP is only used to get a common time to work with, all actual mlat sync is done via the ADSB aircraft.

I have this problem above and I thought I would find people educated and knowledgeable on the subject. I wanted to give my hunch of observations because there are a number of topics that I don't see opening up to the subject and this topic being open, I decided to post ..
and another, remove the topic about MLAT via RPI because it is fake news ...
