I am finding it difficult to know the headers of this data any help would be appreciated. I am trying to create Filter the data so it could appear in one row including info from MSG 1- MSG 8. any help would be appreciated.

Example of the Data:

I’d love to have some header I could use to classify my data like


MSG 1,Flight Id,AirFrame,Altitude,Longitude,Lattitude
MSG 2,Flight Id,Destination,Arrival time, departure time


something similar at least for the different types of messages telling about their entities.

It’s never been specified, it’s mostly a case of producing something that’s kinda like what the Basestation software produces.
There is not a great correspondence between messages on the air and messages emitted on port 30003, because some data (notably positions) is split across more than one message.

The definitive reference for the contents of the columns is the source code, starting around here: github.com/flightaware/dump1090 … _io.c#L519
Generally a particular column always has the same meaning regardless of the message type.
Short version, the columns are:

  • always “MSG”
  • “message type” which is related to the downlink format of the triggering message & some of the contents
  • two dummy fields
  • aircraft address
  • one dummy field
  • local date, time of message reception
  • local date, time of the message being written out
  • callsign
  • altitude
  • groundspeed
  • ground track
  • lat, lon
  • vertical rate
  • squawk
  • alert flag
  • emergency flag
  • SPI flag
  • air/ground flag

Thanks, I think this is helpful
