Synchronized RTL-SDR receivers

[Gisle Vanem]

Does anybody know if the Direction Finding ideas in this repository:
https://github.com/tejeez/rtl_coherent#basic-idea

has been used in ADSB applications? Seems amazing that 3 cheap RTLSDR sticks
mounted on a pizza-box can accomplish what's shown in this video:

Something that would cost > $10.000 in the professional market.

When you are already getting precise location information from ADSB signals I see little value in it. Even if you were planning to use it for MLAT the baseline would be far too small to be of any use.
