"The AS3935 chip only contains an omnidirectional antenna, so no triangulation. It also bears mentioning that the AS3935 was *not* intended to be used as a scientific instrument, but rather as a personal safety add-on in smart phones and stuff to alert the owner to the threat of an approaching storm. It also seems to be extremely sensitive to antenna orientation, so just using it as a personal safety device is sketchy. "
lolwut
Also, that chip is pretty neat, I want one. Shame the weather stations for home use don't have this built in.
