I think there may be something more to this. You're saying celestrak keps are as correct and up to date as the online tracker. However, both HRD and SatPC were wrong for me last night and I know HRD uses celestrak keps, which I know were less than 12 hours old, if not only a couple hours old.
If it helps to decode this mystery, I know my friend running NOVA had the correct info for the ISS pass last night. Tim K6TW -----Original Message----- From: Alan P.

The on line tracker widget gets Keps directly, and so will be as up to date as Celestrak and Space Track. Two different systems, and purposes, which is why there is a difference. You will see a similar situation with ARISSat-1 as it slowly descends. Which is a good chance to get another plug in for the Chicken Little Contest. 73s, Alan WA4SCA -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kevin Deane Sent: Wednesday, October 05, 2011 3:33 PM To: [email protected] Subject: [amsat-bb] ISS Keps So here we are again, Amsat shows the ISS in the right spot but the keps it gives out for automatic updates are around 6 minutes off again. I know about the boosting and why they are off, just dont ubderstand WHY they are good on the online tracker and not anything else?
