ADS-B/C etc is, in reality, just a datalink, what the data is, and what you do with it, on the ground or in the air, determines what use you get out of it.
I think that might be a bit misleading. The
datalinks are UAT, VDL Mode 4 and 1090ES. ADS-B is a specific application of one of those datalinks to allow aircraft to broadcast their own position, and receive the positions of others.
UAT is intended to support other applications, for example weather transmission. 1090ES supports enhanced SSR by sending aircraft parameters in response to Mode S interrogation. Both of those are uses of the datalink but neither is ADS-B.
