The above titanic submersible that went missing can only send short text messages from the ship to the submersible. From my understanding there is no GPS underwater and radio communication is impossible. How can Navy submarines communicate and navigate while submerged in the ocean but the missing submersible can’t?

what amazes me is why this submarine do bot have a sort of a sonar that sends a ping every few minutes and its operation is independent from that of the submarine. I think this will be useful in case the sub has some sort of issue
