[Isocops] IBEX Orbit #501 ATS Approval (16 - 25 Sept 2020)

[Nigel Angold]

Sorry, corrected checklist attached.

Nigel

> I approve IBEX_2020_259_o0501a_BUS_v001.scr for uplink during the next apogee contact on September 2.
> 
> I approve IBEX_2020_259_o0500a_INST_v001.scr for uplink when space to store the 46 commands onboard is available.
> 
> Note: orbit 500 perigee is > 14 Re so 15 Re and 16 Re transitions are used to derive activity times rather than 14 Re and 15 Re even though orbit 501 perigee is < 14 Re. And orbit 502 perigee is < 14 Re but only for 75 minutes so extra attention should be paid to the timing of commands for the orbit 502 ATS.

>> All,
>>    Attached are the planning files for Orbit #501
>> Please respond to this thread with comments and approvals.  
>> Approvals are required by COB on 01 September 2020
>>  
>> 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.
