Which function updates and maintains tracks after initiation?

Explanation:
Keeping track state current after initiation relies on track processing. As new surveillance reports arrive, track processing updates the aircraft’s position, velocity, altitude, and other attributes, applies filtering to smooth data, handles gaps when reports are missed, and decides whether the track remains active, should be merged with others, or should be aged out. This continuous updating is what maintains the track over time. Initiation, by contrast, is the step that creates a new track. Data linking relates to associating observations from different sensors to the same track (data fusion) and can support accuracy, but the ongoing updates are performed by track processing. Flight update concerns changes to flight data or flight plans rather than the live track state.
