Help with port 30003 Data

[Tissy]

I wonder if anyone can assist. I am using Dump1090-Fa and looking at data which is coming from port 30003 and then parsing it for another application. However I am seeing everything apart from callsign, ground_speed and track.

I'm simply parsing the Base Station messages on this port, any ideas to why I may not be getting the above elements please. This is my output from the Balena terminal post parsing.

2024-12-09T12:00:58+00:00 adsb_parser Sending data : {'message_type': 'MSG', 'transmission_type': '3', 'icao_address': '484164', 'callsign': None, 'altitude': '38000', 'ground_speed': None, 'track': None, 'latitude': '53.73935', 'longitude': '-0.49195'}

Many thanks.

@Tissy it might be that that data isn't in the actual message.

In the aircraft.json at /run/dump1090-fa/aircraft.json do you see the same data?

Or does the callsign and other info appear there?
