George, You should note that Doug Royer's experience is almost entirely at sea, and that he usually gets to within 0.1' of arc of his position! Here, he's complaining about aberrant readings on land with an artificial horizon. One other error in Doug's position may come from deflection from the vertical. There was a thread on this about a month ago, and Paul Hirose posted a pointer to an interesting Dutch site over on the Yahoo Sextant forum. That link is http://www.dekoepel.nl/Geodetic-Astronomy.html. Fred
