All, 

   Attached are the planning files for Orbit #603.  Please respond to this thread with comments and approvals.   

Approvals are required by 0200, 03 April 2023. 

  

All, 

    We will be deleting the timed commands for orbit 603 & 604 tonight and up-linking a version 2 Orbit 603 ATS with apogee and perigee sun maneuvers. We are experiencing a star tracker issue that prohibits us from safely performing an inertial maneuver. Here are the changes to note for the new version 2 ATS for orbit 603. 

 

Tonight’s contact: 

IBEX,USHI02,ADD,04/03/23,093,08:00:00,04/03/23,093,09:00:00,,LAHO 2K IBEX-3 Orbit# 603 SC Replace ATS/Blind Acq Contact 40re Asc   

   This will be blind acquisition. The transmitter off command for this contact is in the ATS. A separate transmitter off command will be uplinked at AOS just in case I am not able to up-link the ATS.  

                       

The apogee Descending commands: 

 Original descending commands started to execute @2023/04:04:10:01:48 and now they will be executing @2023/04:04:19:59:40. So, it is important to complete ATS replacement prior to the execution of these commands @2023/04:04:10:01:48. 

 

The apogee contact has been moved: 

IBEX,USHI01,DELETE,04/04/23,094,15:00:00,04/04/23,094,15:35:00,,LAHO 2K IBEX-3 Orbit# 603 Apogee Tracking Contact 43re APO 

IBEX,USHI01,ADD,04/05/23,095,13:00:00,04/05/23,095,13:35:00,,LAHO 2K IBEX-3 Orbit# 603 Apogee Tracking Contact 43re Desc   

The original Inertial maneuver executed @ 2023/04:04:11:57:46 and the new sun maneuver executes @2023/04:04:21:55:38. So the apogee contact had to be moved.  

 

The SSR contact at perigee has been extended to dump both orbits 602 and 603 data.  

IBEX,USHI01,DELETE,04/09/23,099,03:00:00,04/09/23,099,04:00:00,,LAHO 160K IBEX-3 Orbit# 603 SSR_Dump/Tracking Contact 13re Desc 

IBEX,USHI01,ADD,04/09/23,099,03:00:00,04/09/23,099,04:30:00,,LAHO 160K IBEX-3 Orbit# 603 SSR_Dump/Tracking Contact 13re Desc  

 

All Contact changes have been confirmed at the time of the ATS generation.
