    Re: Can I Navigate Without an Assumed Position?

    Hello Ron,

    A quick answer to your case, using ASTROLAB :

    DENEB + POLLUX + SPICA       =>  48° 8.4' N  & 123° 26' W, with a DOP of 2.01 and a resulting statistical error radius of 0.06 NM (95%)

    Same + ARCTURUS (4 Stars)    =>  48° 8.4' N  & 123° 26' W, with a DOP of 1.28 (very good) and a resulting statistical error radius of 0.06 NM (95%)

    DENEB + ARCTURUS (2 Stars) =>  48° 8.4' N  & 123° 26' W (from 2 stars only, DOP and error radius cannot be computed)

    So the results in L & G are quite the same, in any case.

    May be you could change DENEB with another star in the 2-star case ? This should also be provide a 5-star problem...

    Are you from Vancouver island ?

    BR, Yves
