I belong to the radio club VKS-737 and have an HF radio in my camper.
The other day they sent a flyer saying that what3words is now used by emergency services to locate the point of call. A free app is available to download.
I now have that app as well as the normal what3words one.
Anyone else familiar with it? It does not seem widely known yet.
