MLAT - is NUCP always set to '0'?

searched within sources and my data but did not get 100% sure about that? moreover i was wondering if it were possible to set even for mlat distinct values here according to mlat servers perception. e.g. instead of number only 0 an alphanumeric value M0-M11?

cheers

It is always zero, yes.

thanx :slight_smile: would you think the mlat server has reasonable enough data about quality of location-data to output this to aircraft.json in a way i mentioned above?

edit: but maybe this data are flightaware internals that should not go public?
