[Isocops] IBEX Orbit #520 ATS Approval (06 – 15 Mar 21)

[Nigel Angold]

I’m still working on my approval but I note that MPS has timed the perigee activities from the 15 and 16 Re crossing times, presumably due to the lack of time below 14 Re at the end of the orbit.

15 Mar 2021 14:48:58.984 14_Re
15 Mar 2021 15:51:39.793 Periapsis

Just an observation, not a problem.

All,
   Attached are the planning files for Orbit #520
Please respond to this thread with comments and approvals.
Approvals are required by 1700 on 25 February 2021

Please note the following:

1.       Please note that  these products are a  version #2 set.

2.       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.



  1.  No Battery Balancing this orbit

  1.  APL Contact

a.       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
