    It probably doesn't matter that the TLE is three years old.  The
    satellite spends most of its time half the distance to the Moon and
    beyond - the Earth's atmosphere is nonexistent there (I remember reading
    that the Earth's atmosphere is virtually undetectable 1/3 of the
    Earth-Moon distance and beyond).
    
    Typically, how often are geosychronous TLE's (and other satellites in
    even higher orbits of low eccentricity) updated?
