I approve the Orbit 302 ATS. I did have one question however. There are 6 setdownlink commands in the scr file but only 5 contacts in the contacts.txt file. Why aren't there 6 contacts listed?
Regards,
Marty

All,
Here are the planning files and ATS for Orbit # 302. Please respond to this email thread with comments/questions and approvals.
Approvals are required before COB 22 Sept 15.
Please note the following:
1. This Violation happened because there are 2 60minute contacts scheduled for ISN Testing on Oct 8. The time between the 2 contacts is 90 minutes. As we have seen during the recovery. This is not an issue.
==========================
SOFT CONSTRAINT VIOLATIONS
==========================
IBX-CLC-006: Planned transmission at 2015/10/08 01:58:00 UTC - 2015/10/08
03:02:00 UTC is followed by one or more additional transmissions
which, when combined, exceed the maximum transmission time of 5400
seconds within a 18000-second window (total planned transmission
time this window is 7680.000 seconds)
IBX-CLC-006: Planned transmission at 2015/10/08 04:28:00 UTC - 2015/10/08
05:32:00 UTC is preceded by one or more additional transmissions
which, when combined, exceed the maximum transmission time of 5400
seconds within a 18000-second window (total planned transmission
