Celestial navigation pocket calculator program.

I did many sightings with the help of a HP49C... in the 70's, 80's...
Is there a program similar for the Hewlett Packard 12C?
Thanks!

Not that I know of. But you may be able to use the formulae for navigation on this caculator by punching it in directly.

Couldn't find any info on the 49 C but the 12C has only 99 lines of programmable memory. Doesn't look too comfortable for formulas.

Any of the "modern" graphing calculators would probably be a better bet:

I still have my HP 48 with Sparcom's Celestial Navigation Pac.
Brings back old memories from 1992.
