There is another problem in that area.  How accurately is the location of the 
satellite known?  published?

Geo-sync satellites actually wander around their nominal positions.  How much 
does that effect timing?  I've seen figure-8 pictures of the pattern, but I 
don't remember any data on elevation changes.
