"Axis satellite state" is mentioned in the "Protocol Of Proceedings Of Crimea Conference", aka the Yalta Agreement, but it's never defined.

They jointly declare their mutual agreement to concert during the temporary period of instability in liberated Europe the policies of their three Governments in assisting the peoples liberated from the domination of Nazi Germany and the peoples of the former Axis satellite states of Europe to solve by democratic means their pressing political and economic problems.
