Of course DR requires a known reference point. If you weren't so convinced
navigation is impossible without a GPS you might learn how it works.

deducing anything at all about where you are.

simply stated, you just don't know enough about actual navigation to
have the ability to carry on an intelligent discussion on the subject.
BTW, next time you look up "dead reckoning", "ded reckoning", "deduced
