All,

   Attached are the corrected ATS files for orbit #497. The dump time for the APL SSR pass has been corrected. I regenerated the INST ATS with the 497 OEF file. The files have been placed on the MFT server.

Subject: IBEX Orbit #497 ATS Approval ( 9 - 19 Aug 2020 )

All,

   Attached are the planning files for Orbit #497

Please respond to this thread with comments and approvals.  

Approvals are required by 1800 on 30 July 2020

Password is the usual one.

Please note the following:

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.

2. 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.  

3. 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.

4. Battery Balancing this orbit

# Orbit 497 Battery Balancing

# 2020-08-19T01:15:22.583Z,Perigee,orbit:497

  Set Long Eclipse Flag  to TRUE $TIME=2020/08:19:00:30:00

6. APL Contact

Just a reminder for the APL contact. We start off at 2k D\L, after 5 minutes we switch to 320k D\L, Then 5 minutes later we start the SSR Dump With Dump New command

7. Command Load Constraint Violation Report (CCVR)

IBEX_2020_222_o0497a_v001.ccvr

The 2 IBX-CLC-006 violations are acceptable. The reason for the 2violations is because the 2 contacts are within 5 hours of each other. There is 1 hour separation between the  2 contacts and that is plenty of time for the  transmitter to cool down.
