Inertial navigation is a form of dead reckoning. It needs periodic updates (GPS fixes) to stay accurate.
If this however works like some other commenters have theorized (by finding reliable matches to the known contour of the bottom of the ocean), it's not a form of dead reckoning and can instead be used as a fix for dead reckoning.
