Alex, The inertial nav I was discussing was for determining the position of the submarine prior to launch, rather than sat nav, as I had suggested earllier. This is clear to me in the text I quoted, but perhaps not as clear to you, being a non-native speaker of English. It also aligns with my memories of the description of the method, in National Geographic or wherever.
