Well no, not that one as I wrote this program for my HP25 back in 79. I have many reference books on great circle distance and track and have created both the polar / rectangular routine as well as the sin / cos routines.

The books are in storage so I will have to dig them up. But the routines are created by me from standard math or navigation book formula.

But thanks for pointing me at the post, very interesting.
