All,

   Attached are the planning files for Orbit #496

Please respond to this thread with comments and approvals.  

Approvals are required by COB on 20 July 2020

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.

5. Orbit# 494 Reset Master Timer command

The Master Timer Reset Command is set for 2020/07:22:08:45:00. This command will execute on the following contact for Orbit 494

IBEX,USAK01,ADD,07/22/20,204,08:00:00,07/22/20,204,09:00:00,LAHO 160K IBEX-2 Orbit# 494 SSR_Dump/Tracking Contact 13 asc

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

7. Command Load Constraint Violation Report (CCVR)

IBEX_2020_213_o0496a_v001.ccvr

We have 2 IBX-CLC-006 Soft Constraint violations.  The reason it that there are 2 contacts that are  separated by 4 hours and the limit is 5 hours between contacts.  These are acceptable,

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

HARD CONSTRAINT VIOLATIONS

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

NO VIOLATIONS.
