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
