My point about having a "sentenceReceived" at the lower levels has more to do with the question of where to factor the dispatch: *interfaces* typically shouldn't have prefix_Foo methods on them, since you can always have an unexpected prefix_Bar if the dispatch mechanism is expanded. However, "positionReceived" has nice, well-defined semantics of its own, so the interface you've outlined here sounds good to me.
