Hello to all of you !
Please can you help me in order to activate the MLAT for my EXTRPI feeder ?
I have specified the exact GPS coordinates and altitude above ground using the "See instructions" link in the stats page but the MLAT is still inactive.
How to check if the MLAT client is installed ?
Once again thank you very much in advance for your kind help.
Regards.
-
If it is installed it will state MLAT active on the status. What is your station number
Try run "apt-get update -y; apt-get install mlat-client -y; reboot" then setup the Lon and Lat in your station id profile and then will be MLAT ready
Alan
-
Hello Runway31 and thanks for your help.
I followed your instructions but got an error message and could not make it installed.
I am not a linux expert at all and maybe this is due to an old package distribution.
Please see the logs enclosed...
Do you have any clue what to do ?
Regards.
-
Means nothing to me. just gave advice given on another thread which installed the MLAT.. Jessie maybe an old package that doesn't work with that.
Maybe a Linux guru will pass by with some advice
Alan
-
Ok thanks again and well noted.
Maybe a linux guru will show !
As you said Jessie is old.
Regards.
-
Is PGANRB500405 also your station?
Alan
-
Yes it is mine !
It is working fine as it is an Xrange2.
I just had to specifiy the coordinates.
As you said let's hope a linux guru will show !
Thanks
-
I see that MLAT is available on it now
Alan
-
Yes indeed for my Xrange2 (PGANRB feeder), MLAT is now working fine !
But for my Pi (EXTRPI Feeder) it is still not working.
As you said I have an old debian version...

Hello I am trying as well to install MLAT on one of my xRange devices. I followed the procedure and when I run the "apt-get install mlat-client -y" command it says that the version installed is the last one. I have also mlat-autostart=True in rbfeeder settings.
In the status page, however, MLAT is always off and Mlat Autostart is also off!
(https://i.ibb.co/rynYWvw/Cattura.jpg)
Any suggestion?
Thank you
-
Edit your location using the exact lat/lon for MLAT. Failing that contact [email protected] and ask them to have it upgrade to MLAT
I note that PGANRB300389 has been offline for a year??
Alan
-
Hei thank you for the quick reply!
Lat and Lon are correct, and the device is offline because I am not sharing the data but I am using them internally to feed a private system.
I am trying to set up a server (mutability) and connect the 4 xranges I have. Apparently I am not able to do so because maybe I am missing something in the configuration of the device...
-
Are these your own bought units?
Alan
-
Yes they are!
-
I would have thought that they would require to be on the Airnav or other operators network to have the MLAT to operate as the MLAT calculations are carried out on the server software not on the unit. However but I know nothing abut Pi configutation
Alan
-
If you have Raspbian Jessie, it is too old. Please upgrade to Stretch or Buster.
Output of these commands will show your Raspbian version
lsb_release -sc
cat /etc/os-release
For detailed instructions for enabling MLAT on RPi, please see this post:
https://www.airnavsystems.com/forum/index.php?topic=101771.msg389571#msg389571
-
You were right. My version is jessie. Thank you very much for the hint.

Can I update it on my own? Any warranty issue?
-
abcd Will installing the MLAT client be any use if the receiver is not connected to the Radarbox server
Giacomo Regarding warranty the only ones who can answer that are Airnav
Alan
-
Update on my situation: now I have an xRange2 with MLAT active!
Did anyone ever tried to connect to the MLAT mutability server with the xRange? Without feeding radarbox24?
-
As the MLAT software is on the Radarbox server and all the calculations to enable MLAT are carried out there I don't see how you can
For you to have MLAT on your own using only your own receivers not connected to the Airnav server you would need your own MLAT software on your server
Alan
-
I have MLAT running for FA and I believe it is porting to RB, but I am only seeing MLAT aircraft on RB without positions and I don't see "MLAT activated" or anything like that on my station web display. I have the correct lat/long in the config file but maybe I am missing something.
I had it working before but my SC card went about a week ago and had to re-install from scratch.
Any ideas what is missing in my config? Tnx..
-
Yes you are feeding RB24 OK https://www.radarbox24.com/stations/EXTRPI004730
Unfortunately I know nothing regarding Pi's so I cant help with your MLAT query. Hopefully abcd will be along to assist.
Have you tried editing your location exact lat/lon via edit next to your location on your status
Alan
-
Yes I input my lat/long in the "edit position" in DD.dddd format. Wondering if that is the issue should be DD,MM,SS or DD,MM.mm? Will try DD,MM.mmm and see what happens. Also a "-" in front of longitude for west of prime meridian.
According to the zoomed-in map it should be accurate, or at least within 20m I would guess.
..
-
Decimal lat/lon and - before the lon
Alan
-
EXTRPI004730
Your site shows mlat is NOT activated.
To activate MLAT you have to do following two things
(1) Add your location:
Latitude like 49.5615
Longitude like -97.1543
(above figures are only example, use your actual latitude & longitude values)
(2) Install mlat-client:
sudo apt-get install mlat-client
-
Still no go. Tried to build and install mlat client but still no go. Coordinates are good. Must be another issue somewhere... maybe I'll have to remove the RB feeder and re-install...
update:
Found the fix on the FA forum tnx @abcd567!
-
update:
Found the fix on the FA forum tnx @abcd567!
I have posted many fixes for RB Mlat on FA forum, each for a different problem. Can you please provide the link to my FA post where you found the fix, or copy the fix here? This will benefit many others having same issue. Thanks.

Hi all, is it possible to setup MLAT using the radarbax flightstick ?
Im currently setup & sharing ( around 12 months )
station# EXTSHA195185
Any idiots guide would be fantastic
thanks in advance
-
You can I believe as long as your Flightstick is connected to a Pi, you cant if plugged into a Windows computer
Alan
-
@aps
Station numbers starting with:
EXTSHA are Windows Feeder
EXTRPI are RPi Feeder
As your station number is EXTSHA195185, you are Windows Feeder, and as Alan has already told, you cannot have MLAT activated.

Hallo zusammen, wie kann ich bei der Radarbox Extreme 2 die Koordinaten einstellen damit MLAT funktioniert.
Ich komme nicht an die Einstellung.
PGANRB500901
-
Klicken Sie im linken Raster unter Ihrer Stationsnummer auf die Stelle, an der sie steht. Klicken Sie hier, um Ihren Standort zu bearbeiten, und geben Sie dann Ihren Standort Lat / Lon ein
Alan
-
Wenn Sie nicht sehen können Klicken Sie hier, um Ihren Standort zu bearbeiten. Wenden Sie sich an [email protected] und bitten Sie ihn, den Empfänger PGANRB500901 mit Ihrem Konto zu verknüpfen. Sobald sie das getan haben, werden Sie es sehen können
Alan
-
Erledigt, der Support musste mich erst mit dem Account und der Box zusammen legen .
Dankeschön

Kein Problem, ich habe festgestellt, dass Sie Ihren Standort geändert haben
Alan

I AM ALSO HAVING AN ISSUE WITH THE MLAT ON THE XRANGE2 RECEIVER.
SHOWS AUTO START MLAT ON IN THE SETTINGS BUT SAYS MLAT INACTIVE ON MY MAP SCREEN,TRIED ENTERING LAT AND LONG,TRIED WITH STREET.
HAVE NO ISSUES ENTERING THE INFO THE UNIT SEEMS TO TAKE IT,BUT STILL SHOWS MLAT INACTIVE SEE INSTRUCTIONS.
UNIT ID IS-PGANRB501521.
-
Click on EDIT beside your location and enter the exact lat/lon in decimal, click Preview then Save
Alan
-
SO WOULD I ENTER IT LIKE THIS
LAT 53.8219 LONG -101.2531
-
Yes, I use Google Earth to find the exact lat/lon. The lat/lon given gives an address in The Pas
Alan
-
ok thanks,i used my gps for the location.
still shows mlat inactive,and yes i am in the pas manitoba.
the mlat on my fr24 receiver works ok.
thanks again will try and figure it out.
-
It certainly shows your location correctly. I presume that your receiver is linked to your account ok.
I would suggest you ask support for advice as setting the location through Edit is usually all that is required
Alan
-
WILL DO THANKS

A couple of months ago my MLAT stopped working for no apparent reason. I have been an uploader since May 2021 and changed nothing. I sent logs and data to support, no response. Anyway I found a post on this site that solved my MLAT problem, I hope this helps someone else. It would appear this is a software problem that has existed for over a year.

Re-boot required to testart theMLAT client
Alan
-
Reboots is how I kept MLAT running for the past year when it randomly stopped, but no amount of reboots or "sudo systemctl restart rbfeeder" would fix it when MLAT quit about a month ago. I had an error message when running "sudo systemctl status rbfeeder" to the effect:
"File "/usr/bin/mlat-client", line 108, in <module>
adsbexchange rbfeeder[642]: open(pidfile, 'w').write(pid)
adsbexchange rbfeeder[642]: PermissionError: [Errno 13] Permission denied: '/run/mlat-client.pid'
This error cleared when I applied the patches in my post above and MLAT then started working. One can now restart the process with "sudo systemctl restart rbfeeder" and "sudo systemctl restart mlat-client", MLAT now happily restarts without a reboot.
-
@Greytech
That patch was for BUSTER, and worked for you because you have Buster. For those who have BULLSEYE, following is the patch:
To install mlat-client package on RPi with 32-bit Raspi OS BULLSEYE
wget https://github.com/abcd567a/mlat-client-package/releases/download/v1/mlat-client_0.2.11_BULLSEYE_armhf.deb
sudo dpkg -i mlat-client_0.2.11_BULLSEYE_armhf.deb
sudo apt-mark hold mlat-client
-
Thanks for that - I will file this for the future in case I do upgrade...
Cheers Tony

This forum software is 8 years out of date, quite risky to visit this. They try to workaround with a terrible spamfilter ''cleantalk'', all it does is making a normal conversation inpossible on this forum. I gave up on it for this. see also https://forum.radarbox24.com/index.php?topic=103651.0

Hello!
I am new to Radarbox.
I installed RB Feeder and Mlat (Bullsey version with 32 bit) on my Raspberry 4 with OS Bullseye 32 bit.
Everything seems to work fine, except Mlat.
It shows Mlat is working. When I watch it I can see that Mlat synchronize with other stations in intervall and not permanently. I do not know why. When I look to other stations with Mlat it seems they synchronize permanently. Seen on green points on the map. Mine are there for a few seconds and disapear. A few minutes later they will apear again on the map for one minute or so.
Also the amount of Mlat pakets on my Pi are relativ low against others.
I was trying everything what I could find in this forum.
I have no idea what to do, for getting it work permanently.
Maybe the expierienced ones of you will have some ideas what to do?
sorry for my english
Kind Regards
Gerry
-
Gerry, what is you station number?
Alan
-
Hi Alan!
my Station is EXTRPI605343
-
no help ?
-
Can you post your ini file minus your details
Alan
-
meanwhile I have tested FlightAware and ads-b exchange
the best working site is flightaware. there I can see all planes in realtime, even MLAT planes are shown. this is not the case with radarbox24.
the only real advantage RB24 has, is the beautiful look of the site. this is really good made.
But what should it bring when when parts of the software is not working well (mlat) and I can see a delay in data also. Everything compared on one screen with Flightaware and ADSBexchange parallel to each other, Radarbox shown planes are several seconds behind in their location.
As I could see in Forum posts , the problem with Radarbox exist a longer timespan right now and is not to be solved in the next time. It seems that they are not interested helping to solve the problems. Otherwise all feeder deliver data to Radarbox without of cost for them.
-
You dont want to help yourself, I asked you to post your RB ini file yesterday to let me have a look at it to see if anytihng need changed
Have you added your exact lat/lon as you have no syncs so there is someting wrong there but unless you post your ini we cant see
Alan
-
Hello Alan!
update: meanwhile I am using a multifeeder (ADSB.im) and oh wonder everything is working !!
Even in Radarbox is MLAT now working without problem
that is a clear sigh that a mistake is build in in Radarbox software for Pi
Kind Regards
-
There is no issue with the MLAT Client, it was fixed in 2022 and myself and many others have it working with no issues. Normaly the issue for MLAT not working for a user is an issue with their ini file but glad you now have it working
Alan

Hi there,
My station https://www.radarbox.com/stations/EXTRPI004762 is showing MLAT as active, but there are no stations synced. I've confirmed that the correct lat/lon/elevation coordinates exist in /etc/rbfeeder.ini and "systemctl status rbfeeder" is showing both "/usr/bin/rbfeeder" and "/usr/bin/python3.9 /usr/bin/mlat-client ..."
In /var/log/syslog, I have the following (with no further activity pertaining to rbfeeder's mlat):

Hi
I had the same problem and no one had a solution here for that.
But the solution is very simple!
go to Radarbox Website. In the left upper corner you see your stats.
First line is your stantion number and under station number there is your country.
Here you can change your location data. Click on it and put your correct lat and long.
The important part is the sea level. Do not take any numbers from a map.
Take the numbers what Radarbox interface gives you and click enter.
This was the point in my case.
It takes a few minutes and then it will work. Maybe after that start your browser new.
Regards
-
Thanks gerfie for your kind reply. I had known about the easy suggestion you gave, so already tried it. I have been able to confirm that the correct "alt=" value was getting written back to my /etc/rbfeeder.ini file. No luck yet!
-
I presume you have both installed the Radarbox MLAT Client?
Can you post your ini file with your personal details deleted
Alan
-
Thanks for your follow-up, Alan. How can I check that I have the right mlat-client for RadarBox?
I'm unable to post mlat-client version and /etc/rbfeeder.ini info here without being stymied by this web interface's anti-spam misconceptions.
I've attached a screenshot showing this info. Thanks for any insights you can give!
-
It looks ok to me but the only observation I would make is that you are using the older Bullseye OS and not Bookworm but I think it should still work
Have you rebooted the Pi after installing the MLAT client?
My Linux knowledge is limited and I hope abcd picks up the thread and offers advice
Alan
-
Please issue following command:
sudo ststemctl status rbfeeder
@AndreasWarby
If in the output generated by above command, you see following line, then mlat is working ok:
/usr/bin/python3 /usr/bin/mlat-client --input-type dump1090 --input-connect 127.0.0.1:32457 --server mlat1.rb24.com:40900 --lat 43
Please see attached screenshot.
-
Yes, thanks @abcd567, I had checked using "sudo systemctl status rbfeeder" and see a line as follows:
(see attachment for screenshot)
Thanks for any help you can offer!
-
@AndreasWarby
(1) You do NOT need any more help. Your system is running perfectly normal.
(2) In Systemd service, every App has a user assigned to run it. That user is independent of OS user like pi. Following users are used for ADS-B Apps
| APP | USER | GROUP |
| Radarbox24 | rbfeeder | rbfeeder |
| Flightradar24 | fr24 | fr24 |
| Piaware | piaware | nogroup |
| dump1090-fa | dump1090 | nogroup |
Please see attached screenshots.
-
Thanks @abcd567 -- my system may appear to be running perfectly normal, and its status page is showing MLAT as active, yet for several days it's also been indicating "No stations synced".
I appreciate your description of the various organizations' moves away from root.root user.group permissions; however, that does not appear related to a solution for my particular problem.
I can see the running "mlat-client" process belonging to rbfeeder using resources on my RPi, alongside similarly running piaware and ADSBexchange MLAT executables.
Other than the initial connection handshake, there are no further traces of rbfeeder's MLAT activities in /var/log/syslog. I've checked that my coordinates and antenna elevation are all correct. My system clock is disciplined by a stratum-1 GPS system located on the same LAN, so timing info should be well calibrated.
I am still at a loss as to what is going on. I had hoped that some of the log file contents in my earlier post (Jul. 11th) might help to shed some light.
-
You are the expert abcd but would you recommend a purge and reinstall of the mlat client to see if thsat makes a difference
Alan
-

Alan
Yes, sure. It is a good idea and very easy to try. It will clear any corrupt / broken mlat client .
sudo apt purge mlat-client
sudo apt clean
sudo apt install mlat-client
sudo reboot
-
I appreciate the instructions, thank you @abcd567. I performed them, but the situation remains effectively unchanged: rbfeeder seems to be working well; MLAT is active and I can see the process working away; BUT, still "No stations synced".
My station: https://www.radarbox.com/stations/EXTRPI004762
For good measure, I again clicked "Edit" on the above page and re-entered my antenna's coordinates. No luck!
I'm beginning to wonder whether there is a problem on the server (rb24) side of things, perhaps related to the fact that my station was down over the past year while I was overseas. I note, however, that my friend just set up a new rb24 feed yesterday, and his mlat is working very nicely.
-
I am seeing changes on my own page. The red and yellow blocks have now all turned green but at this time although there are aircraft showing on the map I am showing as offline with MLAT active but no stations synced.
Edit 1700 all back to normal for me with 50 stations synced
Alan
-
Unfortunately, I can no longer reply usefully on this thread due to Cleantalk issues. I see that the forum software hasn't been updated since 2017, which is perhaps even more concerning.
Bottom line: I've disabled MLAT feeding to AirNav RadarBox.
-
Welcome.
This is my station: https://www.radarbox.com/stations/EXTRPI015003
I noticed that my MLAT is not working:
(https://i.postimg.cc/RJHbgWGW/sudo-apt-cache-policy-mlat-client.png) (https://postimg.cc/RJHbgWGW)

It used to work normally for me:

How can I fix this?
Best regards.
-
In my case, I have given up trying to help AirNav RadarBox with my station's MLAT data. I had contacted support and, after some back and forth as I re-installed the MLAT package and the problem remained, I was then asked whether I am also providing MLAT services to any other organizations. I replied that, yes, I am providing MLAT for FlightAware and ADSBExchange. After I sent that reply, AirNav RadarBox stopped communicating with me.
Perhaps RadarBox has gone the route of FlightRadar24, who have explicitly requested that feeders providing MLAT to other orgs disable MLAT to FR24 (which I did)? At this point, I've been left to guess that RB detects other MLAT feeds and then intentionally disables any synching. That may protect RadarBox from some bad data, but the methodology (no explanation, poor communication) shows low respect for us feeders.
-
chemitox, have you read the mlat thread on the forum, where ABCD1234 goes through it step by step?
-
MLAT has not been disabled and Airnav has not disabled it if you are feeding elsewhere, MLAT seems to be working fine for all feeders with it on apart from you Andreas They would communicate any requirements to turn off MLAT etc
You just need to look at all the feeders with MLAT set, I myself am showing 47 synced at this time and as you stated a few posts back your friends is working ok, it must be something wrong with your MLAT client set up
Alan
-
rbfeeder.ini is configured like this:
-
I see you are using Buster which is very old version and will probably be your issue, needing to upgrade your o/s
Alan
-
Alan, as a moderator do you represent / speak for AirNav RadarBox? There is at least one other high-performing station in my area that is exhibiting the same characteristic as mine, namely EXTRPI618751. The friend that I mentioned does not have the same setup of feeding to other organizations. Is there a log file I can check to try to trouble shoot from my end? I realize problems and misconfigurations can arise, but the real lament is with the sudden drop of support that I described.
-
Hi Andreas
I so not represnt Airnav in any way ans am not employed by the, I update the database and moderate the forum on a voluntary basis and can contact some Airnav people on specifics
I do not belive the support personel have much in the way of technical knowledge especially in Linux
I note the feeder you refer to has other as his FW version and appears to located in the proximity of abcd1234 or at least is located in the same town. abcd1234 has tried to assist and if anyone can help its him
Alan
-
I see you are using Buster which is very old version and will probably be your issue, needing to upgrade your o/s
Alan
This is true, but I want to use all the possibilities before updating the OS.
Is this file correct? It looks like there is an entry about it.
" Not starting mlat-client daemon, disabled via /etc/default/mlat-client ... (warning)."
-
I dont have the knowledge to answer that query. However I note the lat/lon entries are blank, have you deleted them for the post as they are required for MLAT
Alan
-
No, this file [/etc/default/mlat-client] was like that.
Additionally, it seems to be turned off:
"START_CLIENT="no"".
-
This is my station: https://www.radarbox.com/stations/EXTRPI015003
I noticed that my MLAT is not working:
How can I fix this?
The mlat-client should NOT run on its own, and that is why it its systemd service is disabled. What you are seeing in your screenshot is normal. On all of my many RPis I see the same thing.
When the rbfeeder runs, it issues necessary command to run mlat-client directly, and not through systemd service.
If you check the status of rbfeeder by command "sudo systemctl status rbfeeder" you will see following three lines. Below the line starting with "CGroup", you will find two more lines. The first one shows that rbfeeder is started successfully. The second one shows that mlat-client has been started successfully.
CGroup: /system.slice/rbfeeder.service
├─1322 /usr/bin/rbfeeder
└─1358 /usr/bin/python3 /usr/bin/mlat-client --input-type dump1090 --input-connect 127.0.0.1:32457 --server mlat1.rb24.com:40900 --lat 43.5xxxx --lon -79.6xxxx --alt 155 --user EXTRPI000008 --results beast,connect,127.0.0.1:32004
-
Exactly, that's what I used to have.
I don't see it at the moment.
-
Exactly, that's what I used to have.
I don't see it at the moment.
Seems existing mlat-client package is corrupted.
(1) Purge it
(2) Clean apt to remove saved corrupt package, else apt will again use it when you issue command to install mlat-client
(3) Update
(4) Install mlat-client
(5) Reboot (important step after installing mlat-client)
(6) Check status of rbfeeder.
sudo apt purge mlat-client
sudo apt clean
sudo apt update
sudo apt install mlat-client
sudo reboot
sudo systemctl status rbfeeder
-
Thank you for the detailed descriptions, but unfortunately nothing has changed. MLAT still doesn't work for me.
I think there may be a problem with Python, because when I change the entries in etc/rbfeeder.ini, I get different logs. As you can see at the top, it recently worked for me with the Python 3.7 entry.
Maybe one of the Moderators should delete my entries and move them to a new thread so as not to clutter this topic?

Python version entry in file /etc/rbfeeder.ini is by default commented out (see screenshot below which shows a # at start of mlat line). The rbfeeder uses the version of python which is installed matching with OS version. Please do NOT remove # from start of mlat-line of file /etc/rbfeeder.ini...
It may be possible your OS version is old (stretch or buster) and that is why mlat is not working. Please post output of following command which will show version of your OS

Yes, I have very old images Flightradar24 based on Raspbian 10.
Unfortunately, the above idea didn't change anything.
Is the O/S update the only solution at this point?

Most likely yes, but no guaratees. Try and see. All my Pis with Bookworm have RB24 mlat working ok.
By the way, did you add your latitude, longitude and altitude above sea in your file /etc/rbfeeder.ini ? One reason of mlat not working is this information missing or wrong.

Raspbian 10 = Buster
Raspbian 11 = Bullseye
Raspbian 12 = Bookworm
My 3 RPis are running latest RaspberryPiOS 12 Bookworn.
Mlat works perfectly well.

Is it supposed to mean that after this procedure the rbferder.ini file should be empty?
I didn't have to fill it in because it contained all the data.

Edit your location by clicking on EDIT to the right of your home town on the grid on the left of your station page the enter your lat/lon in decimal when asked then agree with the altutude given then save
Alan
-
Two methods to set location.
Try both one by one, and see with each one if mlat starts working
(1) on your station page "www.radarbox.com/stations/EXTRPIxxxxxx", as described by Alan in his poat above. You must login to make "EDIT" option appear.
(2) in file /etc/rbfeeder.ini
Please see screenshots below
-
While entering the values of lat (latitude) and lon (longitude), be careful to use -ve sign depending on your location. For example at my location (Canada) the lon (longitude) is negetive, so I entered the value of lon with a minus sign , like below:
lat=43.5xxxx
lon=-79.6xxxx
Please see attached image.
-
I see that we did not understand each other.
I don't have to enter anything because I already have this data in the rbfeeder.ini file.
The file has not changed after reinstallation and looks identical to the one here: https://forum.radarbox24.com/index.php?topic=102661.msg581951#msg581951
Previously, as advised, I removed the # before mlat.
I suspect, however, that it should be empty after reinstallation.
-
Your INI file should have your lat/lon/alt included as you have it

Since nothing solved @chemitox's problem, the only option left for him is to re-image his microSD card with RaspberryPi OS Bookworm

I would suggest that is the case

Earlier in this thread (in 2024), I reported an issue with an inability to sync MLAT stations, even though I had activated it and carefully entered coordinates.
During routine maintenance of my Raspberry Pi, I noticed that the rbfeeder package was recently updated. Under rbfeeder version 1:1.0.11+bookworm, I am now seeing "43 Stations Synced".
Is there a changelog for rbfeeder anywhere that I could consult to understand what has changed?
-
I suggest you ask Airnav

Hello everyone. Hi @abcd567 and @Runway31.
I've had a station for a few years, but it never ran properly. Now I have redone everything in the last few days, replaced the hardware and apart from the MLAT service, I am very satisfied. Can you help me? MLAT active (No stations synced).
Result of (sudo systemctl status rbfeeder | sed ‘s/ / /’):
CGroup: /system.slice/rbfeeder.service
├─591 /usr/bin/rbfeeder
└─603 /usr/bin/dump1090-rb --write-json /dev/shm/ --net --quiet --mlat --forward-mlat --net-bo-port 30105 --lat 52.XXXXX --lon 9.XXXXX --modeac --fix --adaptive-burst --adaptive-range -gnss
I made the settings for the position via the interface. Values anonymised:
Result of (sudo nano /etc/rbfeeder.ini):
[client]
network_mode=false
log_file=/var/log/rbfeeder.log
key=dxxxxxxxxxxxxxxxxxxxxxxx
sn=EXTRPI027193
lat=52.XXXXX
lon=9.XXXXX
alt=69
[mlat]
autostart_mlat=true
#mlat_cmd=/usr/bin/python3.9 /usr/bin/mlat-client
[dump978]
#dump978_enabled=true
I have also reinstalled the MLAT service:
sudo apt purge mlat-client
sudo apt clean
sudo apt install mlat-client
sudo reboot
Of course, I also rebooted the Raspberry and gave it some time to boot up and start all services. If you still have questions about the current system:
Result of (cat /etc/os-release):
RETTY_NAME="Debian GNU/Linux 12 (bookworm)’
NAME="Debian GNU/Linux’
VERSION_ID="12’
VERSION="12 (bookworm)’
VERSION_CODENAME=bookworm
If you want to know which station it's about, have a look here: https://www.airnavradar.com/stations/EXTRPI027193 (https://www.airnavradar.com/stations/EXTRPI027193)
I would be grateful if you could help. Now I would like to have all services running and not a ‘half-finished state’ like before.
Greetings

Hi 391P
Would I be correct in thinking you are using an older version of the Pi OS?? Reason I was asking is that the MLAT client is now within the latest version of the RB software see reply 9 of this thread https://forum.airnavradar.com/index.php?topic=107991.0
Only thing I can see so far is this from a previous post from abcd which will be helpful if using an older Pi os version
Python version entry in file /etc/rbfeeder.ini is by default commented out (see screenshot below which shows a # at start of mlat line). The rbfeeder uses the version of python which is installed matching with OS version. Please do NOT remove # from start of mlat-line of file /etc/rbfeeder.ini...
Maybe worthwhile commenting it out

Hi Runway31.
Thanks for the tip. That was a mistake on my part when transferring it to the post. The value is correct in the *.ini! I have just checked the Phython version, it is 3.11.2 installed.
Greetings
391P
PS: I have noticed that the data statistics do not register / record any values for MLAT.
-
See the amendment I made to my post
Alan
-
I have also updated content.
Result of (cat /proc/device-tree/model; echo);
Raspberry Pi 3 Model B Rev 1.2
Result of (uname -m):
aarch64
Result of (python --version):
Python 3.11.2
Result of (rbfeeder --version):
RBFeeder v1.0.11 (build 20241022110000)
I have now installed all updates again and restarted. Let's see if the MLAT starts now. You can see the status on the website of the station. I won't be able to reply until tomorrow ;-)
sudo apt update
sudo apt full-upgrade
Greetings

MLAT is active on your station with 54 synced

Hi @Runway31
Thank you for the positive feedback. I noticed today that the first MLAT data packets were sent after updating the Raspberry yesterday. In the last few hours, however, the station has continued without successful synchronization.
That's why I sent an email to support a few hours ago. After I had no idea what could be wrong with the configuration - because MLAT data was also sent in the meantime.
Great! Now it works. I would still be interested to know what the missing piece of the puzzle was or it simply takes a while for Airnavradar to release the function...
In the same way, after restarting the Rapsberry several times, the error message appears that the sharing key is invalid. But after about 30 minutes everything is fine again.
Greetings

I would be interested to find out myself, I have a suspicion there was something wrong at the server end
