    Re: Accuracy of sextant observations at sea

    To complete my previous post :

    "1.2 - Then, IF - and only IF - we assume that there WOULD BE be a constant and systematic error in your measurements, such error would amount to 0.29 arc minute. If so, through reworking all data (i.e. removing 0.29 Arc minute to all your intercepts), we would get a "systematic error free" OP in Azimuth 355.78° and at a distance of 0.18 NM from your DR Position. "

    ... please be so kind as to include the following :

    " And we would then get a new "Standard Deviation" equal to 0.22 NM for this set of seven shots."


    That's all folks !
