Hello,
I followed the same iterative method as earlier: first intersect the circles of position to get an approximate AP (taking into account the distances traveled while doing so), using that AP in a lunar distance time calculation to find the watch correction, which is then used to intersect the circles to get the fix. A final lunar distance is used to check the watch correction from fix position.
With my code I find the following:
time of lunar distance sight: 18:13:30.2
at fix: 46°36.5'N 002°22.1'W
(With a residual 1s watch error from the last check.)
Again thanks for an interesting problem!
Cheers,
Harri
