Re: The "Death to the Intercept Method" revisited?

Hello!

I think to try a two-pass approach to the direct calculation method:

take two sights and do all the calculations according to the 7.5x formulas (pretending both sights were taken simultaneously) - thus obtaining a preliminary position;
using that preliminary position data - to consult the H.O.249 vol 1 regarding the azimuth of the body of the earlier sight;
with the azimuth (though not precisely accurate) do the advance of the H₁ to the moment of time of the second sight;
now one may repeat all the 7.5x formulas with the advanced H₁ - hoping to arrive to a reasonably more accurate position fix.

Please comment.

Regards,

Tony
