It sounds like a TCAS display, where you can see other traffic with altitude readout, so most RPT would have the traffic display portion in some amount these days. While ADSB-IN is not fitted to many airliners, TCAS II does the job currently, however no weather input or anything like that. Both systems require that the rogue aircraft also have transponders, however TCAS directly reads the other aircraft signal rather than get information from a ground transceiver.
