All,

   Attached are the planning files for Orbit #525. Please respond to this thread with comments and approvals.  

Approvals are required by COB on 09 April 2021

 

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. I placed the following note in the ATS because of an overlap in the orbit 524 & 525 ATS’s. This is acceptable.  The contact occurs between the execution of the Ascending Bus Commands and the Ascending payload commands.

 

# Note Orbit# 524 SSR_Dump/Tracking Contact 15 Asc 2021/04:21 19:30:00 - 20:30:00

 

5. Battery Balancing this orbit

Begin 2021/04:30:15:00:00– End 2021/04:30:16:30:00

 

6.       # Orbit# 522 Reset Master Timer  - 2021/04:12:12:45:00

 

7. APL Contact 2021-04-30,120,21:00:00 - 2021-04-30,120,22:00:00

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
