[Moon-net] Moontracking - PIC

Hello,

With the availability of powerfull new Pic families , I am looking from 
someone from the EME community who succeeded in computing  the moon 
position  (AZ,EL, 0.1° accuracy)  on a seldom 'rather small' _*microchip 
Pic*_ (like a 4550 or equiv) and in C langage (on the paper, one just 
need a realtimeclock , lat lon coordinates + the right algo).

I need to substitute (translate remove) the link between the tracker and 
the Pc for Expe purpose. My first experiences on a 16F877 went 
unsuccessfull, too many stack calls and the trigo was 'Pic consuming'.
I am currently working on another solution based on a static table 
containing downloaded moon positions but 5 days of tracking with 0,1° 
infos with a 8k eeprom is the far end, and I need roughly 10 full passes.

Please answer to me offline,
Kind regards
Jean-marc F1HDI
