Well, off hand, I don't see how. The pingers won't emit at the same time, because they are independent devices. We had a long and inconclusive discussion about whether the oscillators are crystal controlled, or not. Even if they are, the pingers will have random and slowly changing time shift; if they are not they will have rapidly changing shift.

I am just hoping that Emeraude really heard anything at all. There seems to still be uncertainty about that.
