– How can Navy submarines communicate / navigate but the missing titanic submersible can’t do either.

Question

Context: https://www.bbc.com/news/world-us-canada-65953872

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?

Answer 1

also, it serves to mention that OceanGate, the private company who’s sub is missing, has the only model of this submersible and was designed by the company founder. It’s literally one guys dream machine created for Titanic tourism. The only communication it has available is rudimentary text messages to the ship, plus sonic pings every 15 minutes.
