    Re: estimating speed and course along with position
    From: Jeremy C

    I will try, but when we go out on these short exercises, we often vary both speed and direction at fairly frequent intervals.  I am going out next week, but with a new captain.  I will see what we are doing in the mornings (the time I will see both sun and moon out here) and see what I can do.

    during navigation with approximately constant course and speed, a sequence
    (at least four) of Sun/Moon fixes spanning a few hours (> 0.5 Hr, 2Hr?), and
    with a sufficient azimuth spread, allow to estimate both speed and course,
    along with position.
    Are you willing to shoot, once, these measures for me?
    I'm actually want to check how accurately Least Squares perform in this
    joint estimation.
