    Thanks to Dan for that fascinating piece.
    
    Like the sextant, I wonder how far this techonology would have gone had 
    satellite GPS not come on to the scene?  Not knowing the technical 
    difficulties of the system, it seems to me, notwithstanding cloud cover, that 
    this would be a far superior system to the current GPS system in terms of 
    anti-spoofing and self-sufficiency.
    
    As for Greg's question about using it on a boat, I am confident that it would 
    have been successfully tailored to this purpose.
    
    Up here in northern Canada we have a saying when faced with a particularly 
    difficult construction or engineering problem: (with no offence intended to 
    my American friends): "Tell the Yanks that the godless commies are about to 
    invade and they will figure out a way to build it/make it work."  Anyone who 
    has ever seen the Distant Early Warning sites that were constructed in Arctic 
    during the 1950's would appreciate just how true this is.
    
    I am guessing that the size of the astro tracker would have been signficiantly 
    reduced had its development continued.
