I note in the Draper slides that only lines of position from two different celestial bodies are required to determine position. But unless the relative azimuths are ideal (90 degrees) and error sources are zero or ignored, it’s been a better practice to have at least three LOPs from bodies roughly 120 degrees azimuth apart, in order to triangulate and minimize contributions of systematic error.
I don’t know the technology, but I suppose they have a way of observing stars even in daytime.
The SR-71 had astro inertial navigation so this doesnt sound like anything new (R2D2). I guess they hope miniturise and improve accuracy for weapon purposes
