Dear Antoine: I for one would very much appreciate receiving this program...if not too much trouble. Thanks irvhaworth@shaw.ca -----Original Message----- From: navlist-bounce@fer3.com [mailto:navlist-bounce@fer3.com] On Behalf Of Antoine Couette Sent: Monday, September 20, 2010 11:01 AM To: NavList@fer3.com Subject: [NavList] Re: sextant practice and time keepers Alan, Since you mentioned "Trig, courtesy of my old HP 11C is easy", just in case it might be interesting to you - and provided HP11C will accept programs from its HP-25C "ancestor" - I can send you an HP25C program which does it all (compute both true azimut from North as well as intercept) in just 49 lines with angles entered in decimal format. I never could find out who was its Author. At its time, this fundamental CelNav Program was regarded by the HP25C Community as one of the very best programs ever written for this machine, almost as impressive as the "geniously devised" most celebrated then 4th order Runge Kutta program written by Valentin Albillo. If you think that this Celnav Computation program could be of some interest to your needs, please let me know (antoine.m.couetteATclub-internet.fr) Best Regards Antoine Antoine M.
