I imagine it would. But it would have all the problems of a visual sighting – you could get false horizons if there was an inversion layer or a warm set of clouds. The FLIR sees heat, after all. Interesting idea though.

Could FLIR technology be applied to a sextant scope to enable one to view the natural horizon after dark, thereby extending one's ability to take celestial sights at night, beyond the usual periods of nautical twilight?
