Hello,

I have finally added Earth satellite tracking to KStars using SatLib; see the 
attached screenshot.  However, I'm having trouble verifying that the 
predictions are accurate.  I'm comparing to websites like heavens-above.com, 
and it looks to me like the SatLib predictions are completely different.

Quoting an earlier email on this topic[1]:

I've tried several other dates as well, I can't seem to find any correlation 
between the SatLib predictions and those published at heavens-above and NASA.

I was wondering if you had any insight in this matter.  Have you done any 
verification of the SatLib predictions?  If so, can you share the sources you 
compared with?

thanks,
Jason
