PLAN-13 Satellite Position Calculation Program
G6LVB has a really nifty website, which includes plans for a neat little PIC powered antenna tracker. The writeup says that it used the “Plan 13″ algorithm for G3RUH, which I had never heard of before. A little judicious Googling reveals:

This algorithm seems much simpler and more straightforward than the SGP4 stuff that most other programs use. I might just code this up in Python (or C maybe) for future experimentation.
