Pass time differances from this site and my NOVA tracking program

k0hzi – June 30, 2008 – 13:11

At 13:07 UTC this site advises that the next pass over my location is 1 Hour 20 minutes. Nova is showing about thirteen minuets to the pass at 13:15 UTC. Checked the town location and seems to be correct. Even if change this site tracking time to one hour less for DST the pass time is still off?

Hello K0HZI,

If I doubt about ISS position I compare often with
spacecweb real time tracker.

Seems that anytime the ISS does a reboost or maneuver this site takes a while to update the keps associated with the new predicts. Once the webmaster does that, they are accurate until the next reboost.
