Madre mía. Bueno porque no os unís a nosotros¿?? www.opengeomap.org
Que bueno sería unir conocimientos informaticos y técnicos. 
Absolutamente toda la ciencia es libre.
Como siempre nadie me hará ni caso, pero yo siempre intentandolo...

El otro día me mando un correo el cientifico japones de la agencia 
espacial japonesa:
Me paso código fuente de su puño y letra en fortran:

More than a decade ago, I initiated a similar project named SOFA
in the fundamental astronomy under the auspices of the International
Astronomical Union, which is now maintained by younger people;

Such activities should be highly respected and I believe these
will be a sort of cultural heritage in the long run...

Sure.

I attach some files (in plain ASCII text) you may need;

1) xgconv2.for; Test driver for the conversion routines
2) gconv2h.for; Conversion routine based on single usage of
                Halley's method = Routine (f) in my article
3) gconv2n.for; Conversion routine based on single usage of
                Newton method = Routine (e) in my article
4) gconv2h.out; Test output for "gconv2h"
5) gconv2n.out; Test output for "gconv2n"

I hope these will be a little help...

 >Do you use computers of 64 bit?

No.

 >That precision you need for their works?

The so-called double precision computation in the IEEE standard is enough.
