Submarine navigation

He either means "dead-reckoning", which is very old, no doubt age of sail. Or a very modern computer kind of navigation. There must be a translation thing going on here.

I was looking at the report into the grounding of HMS Trafalgar in 2002 during a Perisher.
The board of inquiry report can be read here:

Copies of the chart can be seen here:

I would guess that DR.Sid is probably closest at the accuracy of a fix decreases with time and motion.

Good reading. Anyway they talk about manual dead-reckoning assisted with bottom sounding. Which means plotting actual curse and speed to get actual position, with depth reading to get at least some confirmation.
Btw. isn't this the method Ramius used in the Hunt during the canyon run ? At least the movie version. It seemed good enough for them
