I am embarrassed. I bit on the premise without defining "external." Given
the technology necessary for Bauer's sextant and the subsequent blue-sky
suggestions, what do we exclude? Earth radio waves (Loran etc.) that don't
leave the earth and bounce off satellites?
Are man-made satellites external? If so, would the sun, moon, stars and
planets not be "external" satellites given the cel nav model where the
heavens revolve around earth? A slippery slope?
