In the past about 10years ago there was a very powerfull standalone tracker 
with a 8051 (these days antique)
It was called "Trakbox", there is also OE5JFL's stand alone tracker.
But I agree with you that it is more than time to have a
modern standalone tracker now that such a powerfull
MCU's excists like microchip and atmel

If you have any knowledge of someone who is develloping this please let me 
know

Walter

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
