    Gyro Error
    From: Byron Franklin
    Date: 2012 Aug 16, 09:17 -0700

    Byron:Jeremy , To any one on a ship with gyro. Many years ago I was sent to
    various ships to check on navigation, especially on the gyro and alignment.
    On boarding the majority of ship I was told that gyro error was zero.
    After a quick around of bearing using the Franklin Piloting Techique I found
    error in most ships, most was gyro error and a few with alignment.
    Example was the Intrepid; she left the yard after her gyro was worked on
    and traveled to Norfolk VA. Than to RI. Without notice that
    she had a one. Five EAST gyro error. She got underway with me watching her
    chart fixes;(never touched the chart) within ten minute I told the Navigator she had a one. Five east error.
    (This proved correct.) Is this a big deal? Maybe? She ran aground right where the DR using
    the unknown 1.5 error would put her. Coincidence?
    What I would like is, any one in position to use the technique along side pier, anchored or under way, or check fixes after the transit.use the technique and check your gyro, Let me know what you found.
    Don’t think you equipment is new, up-to-date, and you never had a problem.
    Take that extra step you may learn a lot. I would appreciate feed back even if 0 error.
