[Isocops] IBEX Orbit #510 ATS Approval (7 – 16 Dec 20)

Thu Nov 19 16:55:41 EST 2020

All,
   Attached are the planning files for Orbit #510
Please respond to this thread with comments and approvals.
Approvals are required by COB on 26 November 2020

Please note the following:

1.       Please note that I am moving out the date for sign off to the perigee passes. I plan to uplink the Orbit 509 LGC ATS during the apogee pass on Nov 22.

2.       The Apogee pass had to be changed. With the new ephemeris the original view period disappeared

  1.  I generated 3 separate ATS files BUS, INST and a complete file. The BUS and INST will be the files to be uplinked. The complete ATS, I used as a sanity check to see how the commands lined up. Since we are in a new phase of ATS generation. IF you have any ideas of doing this differently, let me know.

  1.  The 3 ATS files have been changed to word files and encrypted. I will send out another email with the password. The files that have been transferred via MFT have not been encrypted and are still text files.

  1.  I moved the 2 House Keeping commands from the INST ATS to the BUS ATS. I commented out the 2 commands in the INST ATS. If for some reason we were unable to uplink the INST Commands for this orbit, we would have been in the wrong spacecraft state for executing the maneuver commands.

6.       Eclipse – Eclipse Duration 2020-12-15T12:37:55.730Z,PenumbraEntry,orbit:510 - 2020-12-15T14:00:41.598Z,PenumbraExit,orbit:510
Long eclipse flag 2020/12:15:10:45:00 True - 2020/12:15:14:10:00 False

8.       Command Load Constraint Violation Report (CCVR)

==========================

HARD CONSTRAINT VIOLATIONS

==========================

NO VIOLATIONS.

==========================

SOFT CONSTRAINT VIOLATIONS

==========================

IBX-CLC-006: Planned transmission at 2020/12/15 10:28:00 UTC - 2020/12/15

             12:02:00 UTC exceeds the maximum contiguous transmission time of

             5400 seconds

The reason for this violation is that we add 2 minutes before and after the scheduled time. So, the additional 4 minutes creates the violation.

IBEX,USAK01,ADD,12/15/20,350,10:30:00,12/15/20,350,12:00:00,LAHO 64K IBEX-2 Orbit# 510 Pre-Eclipse Monitor Contact 14 Desc

IBX-CLC-015: Battery charge falls below minimum from 2020/12/06 18:30:00 UTC -

             2020/12/15 23:32:00 UTC. Lowest charge level is 0.000000

             watt-minutes during this interval.

I am assuming that this violation is because of the eclipse. I am not sure why the duration is the length of the orbit.

IBX-CLC-016: No command to enable spin pulse protection was found after

             transition to science mode at 2020/12/07 01:46:26 UTC
