Simulate past passes in MacDoppler w/o changing OS date/time?
I just setup MacDoppler last night and got it to do basically what I wanted but I can't figure out if it's possible to simulate past/future passes beyond the 6 hour +/- changes you can make with the slider. I can get beyond that limit if I change the system date/time but I'd prefer not to have to do that to get what I want.
I did see you can get predictions for anytime but what I'm interested in is not just that, but watching the map from the past passes.
Is there a way to do that?

After extensive research and experimentation, I was able to reliably handle past pass prediction using Orbitron.
predict on the command line also works, but Orbitron is more flexible for day-to-day use with past passes.
Orbitron is Windows-only, FYI.

Yeah, I normally use Orbitron and it does this easily, but I'm travelling and all I have is a MacBook Pro. I guess I will virtualize windows so I can use Orbitron easily in the future.

It would be lovely to learn how to make MacDoppler do the same thing!
I am sure that *enough* research would result in the same for GPredict.
I was satisfied with Orbitron, so I left it at that. If it's enough for Captain Yuri...

GPredict does future passes quite well.
If you go to the lower right box and click on the "down arrow" just to the left of the satellite name, it has an option to show future passes.

Hi
Not sure how the SGP4 algorithms will cope with old prediction if it is before the TLE reference date.

They would be incorrect, of course.
I should elaborate -- I definitely used contemporaneous TLEs from the time period I needed.
Thanks for bringing that up!
