    No, the INS was for the submarine and came in, I believe, in the late '50s, for some reason 1957 sticks in my head.

    Also there were other electronic systems that provided accurate navigation. LORAN-A, since WW2, LORAN-C in the '70s, and OMEGA.

    Fred,

    I suppose that when speaking of "inertial nav" as a guidance system,
    they mean the nav of the missile itself, not of the submarine.

    To use an inertiale nav in the missle one needs the position
    of the starting point. This is what Sat nav was for.

    Now we see Shufeldt's report in new light:-)
    The reaseach was made in 1957-1961 :-)
    And then classified.
    Exactly at the time when they developed the Polaris A-1 missile...

    When Transit became available, they declassified the Shufeldt report.

    So now we know what "Precision Cel nav" was really for:-)

    Alex.
