Open Live Script

Create an ADS-B receiver.

receiver = adsbReceiver;

Define ADS-B messages generated from transponder AAF123. 

airbornePositionMessage = struct('ICAO','AAF123','Time', NaN,...
    'Latitude',70, 'Longitude',30,'Altitude',2000,...
    'Vnorth',250,'Veast',0,'ClimbRate',-1);

Call the receiver to generate tracks.

tracks = receiver(airbornePositionMessage,0)
tracks = 
  objectTrack with properties:

                     TrackID: 1
                    BranchID: 0
                 SourceIndex: 0
                  UpdateTime: 0

                 IsConfirmed: 1
                   IsCoasted: 0
              IsSelfReported: 1
            ObjectAttributes: [1x1 struct]

Delete the track.

tf = deleteTrack(receiver,1)
tf = logical
