    Fred,
    That's interesting.
    Today, while exploring a new search engine
    from Google, I found several indications
    that CelNav with real sextants and real
    horizon (!) was used in at least two space missions:
    Skylab and Soyuz-17. Unfortunately I could not locate
    complete articles but only their resumes.
    Alex.
