[amsat-bb] Re: ISS/STS-126 Position?

[Scott Schmautz]

Thanks for the answers guys. I was using what I assume are current keps. I
was using Orbitron and the tracking segment  of Ham Radio Deluxe. What I did
notice is that the position seemed accurate until docking, then
the difference became noticeable as Alan had described in his message.
Again, not a major issue, just curious as to what was happening.
For Alan, WB5RMG, wouldn't  the subsequently released keps bring the ISS
position into line? I imagine so, I think the programs were using keps from
Celestrak, AMSAT, or Space Track.

Thanks!
