We're still working the timing issues due to various products being
derived from different forecast OEFs and/or predictive files and I think
we won't have time to fix that and have the ATS approved before the
second perigee contact tomorrow. So I guess we'll uplink the 660 ATS
during the apogee contact on Aug 25 or next perigee on Aug 30-31. It's
good that we have margin built into our process.
It's not what I'd hoped for because I'd like things not to back up given
that I'm traveling from Thursday onward for a couple of weeks. But it is
what it is.
I'd like folks to think about the root cause of this problem so we can
discuss and figure out how to avoid similar issues in the future.
Thanks,
Nigel
