Submarines do not have to surface to get a GPS lock.

https://en.wikipedia.org/wiki/Submarine_navigation

"On the surface or at periscope depth, submarines have used these methods to fix their position"...GPS being one of them.

A submarine can also navigate by the stars without surfacing.

"This is precisely the information required by the traditional method of celestial navigation, and it is accomplished without the need to surface or use a sextant!"
