Of course, the VC-25A used as Air Force One has a cockpit station for a navigator, specifically so that it can use old-style navigation methods if access to GPS and other navigational aids is lost. Putin's modified Il-96-300PU may well also have one.

Given how crazy precise (and expensive) inertial guidance systems were developed for ICBMs in the Cold War I have to imagine though they have one on Air Force One, along with an automated celestial guidance system for recalibration. The AIRS (advanced inertial reference system) used in the LGM-118A Peacekeeper missiles have to be some of the most mindblowingly precisely made machines in human history. Drift of something like 1.5/10000° per hour! .003° per week (not that they'd ever run that long obviously, ICBM and all). At any rate, highly precise IGS is doable for enough money, even with older tech though these days I'd assume they're using fiber optic gyros or something like that. It's a neat area.
