I am using SS6.0.0.24 in iOS 11.2.1 on a 2017 iPad. See attached screenshot. The time stamp on the satellite path appears to be shifted by one minute. Notice the time on the clock, the position of the satellite, and the ticks along the path.

I think I've asked Tim about this previously. If I recall, he said the time ticks for things like satellites have to be somewhat approximate. Just not possible to do all the calculations for fast moving objects in real time and be more precise. The satellite's position is accurate but the time ticks are approximations. I will double check with him about this.
Bill, I don't get your point. You are able to calculate the exact position for *tens* satellites in real time, but can't calculate reference point for just *one* satellite only once (on selection)?
This has been fixed in 6.0.1.
That's great news for those who follow Iridium flares! Thanks a lot!
