Archived - Beta test MLAT software for Raspberry Pi

[Mike]

Positions are now live on the map. Just filter for T-MLAT7

I though them will more accurate.

MLAT7 is probably just a temporarily code to find and analyse the new data. In the future code will be same as region.

I think i can help can someone give me a pointer as to what DVB-T "stick" that should be used ?
Also feel free to poke about porting it to Linux Standard Distro

Cheers

Yeah, was surprised to see 7 MLAT7 A/C in the Las Vegas area today. It will be fun to watch the progress here, a big city surrounded by a whole lot of nothing makes a good benchmark.

MLAT7 spotted near YMML (Melbourne, Australia).

Thanks for your feedback!
A new decoder version 1.0.13-9 has been released which will be the release candidate, perhaps the last one

To update:

$ sudo service fr24feed stop
$ sudo apt-get update
$ sudo apt-get install fr24feed
$ sudo service fr24feed start

Changelog:

• MLAT settings & status are now visible and configurable at the web interface
• A link added (when available) to FR24 site in tracked aircrafts list (web interface)
• Libraries are now located in /usr/lib/fr24 to avoid conflicts with system libraries

As some of you already spotted, T-MLAT6 and T-MLAT7 radars are visible on FR24 web site and correspond to the latest MLAT improvements.

Is Raspi MLAT combined with regular MLAT, or are they only correlated with other Rpi-MLAT-Receivers?

This one just flew past my spot, but I don't think i've contributed to the locating calculation.
