Comments
From the promotive material of the Military Technical Institute:
"Vrtio is the first system that utilises phased goniometry on a platform like the J-22 Orao. It consists of the airborne elint container and a ground station for the reception, processing and displaying of the emission sources. The ELINT container is remote controlled from the ground station."
This one was developed approximately from 1985-1990. It likely has specific emmiter ID since the received data is processed at the ground station where you have much more processing power.
