What does GERTRUDE refer to in underwater communications?

Explanation:
GERTRUDE is a named underwater telephone system—equipment that enables two-way voice communication through water. In the underwater environment, acoustic signaling is used because radio waves don’t propagate well in seawater, so voice is carried as sound. An underwater telephone setup links a submarine (or diver) with a surface vessel or shore station using hydrophones and transducers to convert voice to sound in water and back again. That makes it the best fit: it describes the actual hardware and function for underwater voice contact, rather than a digital codec, one-way transmission, or a generic piece of equipment.
