[Isocops] IBEX Orbit #504 ATS Approval ( 13 Oct 20 - 22 Oct 20)

[Nigel Angold]

I approve IBEX_2020_287_o0504a_BUS_v001.scr for uplink during the September 30 apogee contact.

I approve IBEX_2020_287_o0504a_INST_v001.scr for uplink when there’s space to store the 46 commands onboard.

Two orbit 504 INST commands (Science State and Lo Science Mode Normal ) overlap with orbit 503 BUS (Tx commands) commands. But that’s ok. 

We’ll need to deviate from this uplink cadence in orbit 503 to load the orbit 504 Hi Gain Test ATS.

Thanks,
Nigel

> Please note the following:
> 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.

> 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.  
>  
> 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.
