RE: I give up... Don't try this!



More to the story.

This only happens with opal or any of the new sats.  Is there some sort of
error factor that happens with new sats.  I find this pretty odd.  On ao-27,
wisp32 and nova as exactly the same to the sec.  But on opal, they are off
by 56 sec!

Hi Alan,
I recently was testing Uni_Trac against some of the programs you mentioned.
I had in fact 7 different tracking programs running simultaneously on this
PentiumIII 500. I dont recall errors of the size you mention.

73
