offending simulation archive, run leosats.sim
attached an offending scene.. crashes for me *always* at 22.6% into the first frame of the simulation.
changing the ECF lookat location from:
to anything else, such as:
seems to get around the crash and let it run correctly. not sure why.
I was able to reproduce the crash. I will dive into this one ASAP.
So what you stumbled upon was actually a high-level bug related to setting the geolocation corner points in the ENVI header file. We ended up poking the scene with rays that had an invalid time and that caused the motion model to incorrectly position the scene objects. I am successfully running with a fix now.
All of our testing seems to have confirmed that scenes with dynamic content are no longer corrupted by the probe rays that didn't have a valid date/time.
