If you have been doing comparisons today, your keps are old. The ISS did a major reboost early today and that will cause your times to be off. It will take a bit for the predicts to catch up but you need to have the latest keps downloaded for the day of the contact.
If you download a new set this weekend, you should see the predicts line up with the live NASA telemetry.

Hi folks:
I would greatly appreciate your help with using SATPC32 for a contact with the International Space Station this Tuesday. I have been using the program successfully with satellites, but it does not seem to be tracking the ISS correctly. When I use SatPC32ISS, I notice that the AOS time is 5 to 10 minutes different from what is reported on the NASA "real time" tracking web site. Since the ISS has been quiet lately, there seems to be no way for me to confirm if I'm tracking it OK. I've updated the Keps through the main program's "Satellites" menu.
I thought that I would have a little more time to work on this, but they just moved us up in the schedule!
Any advice would be most helpful.
Ken, N6KTH
