DGNSS differential corrections

Got a question regarding what types of differential corrections you can get for DGNSS?

You have satellite corrections such as SPOTBEAM etc… but can anybody add to this list? I’m sure there are more.

There are also UHF corrections, but do people know many types of them you can get?
