It might be possible but I doubt it. There used to be a sextant
designed for aircraft navigation in WW II that used an artificial
horizon of sorts but those guys were happy to know where they were
within 20 miles or so.

That was not a sextant. It was called an octant.

Here's one:

I've got no idea what that thing you referenced is but I can assure
you that the devices carried aboard aircraft, at least until the
1970's was called a "Bubble Sextant" and didn't look a thing like your
picture.
