[Isocops] IBEX Orbit# 133 ATS (18 July 11 - 27 July 11)

Fri Jul 8 10:24:11 EDT 2011

Hey Tim, turns out my description was not quite right. See an excerpt
from Ken's email below:

I want to clarify the question about command timing at perigee.  The
software currently does not refer to the forecast OEF to determine when
the maneuver will actually take place.  This means that, regardless of
when in the window the maneuver takes place, we always assume that it
occurs at the start of the maneuver window (currently 10Re + 1/2 hour).
That means that the housekeeping command will always be at 10Re - 1/2
hour.

 Ok. I just wanted to ask.  I'm good with the ATS.

I had asked about the Housekeeping timing too Tim!

The ISOC SW looks has 2 rules for the transition to Housekeeping : 1) 1h
prior to a maneuver, 2) At 10Re desc.

When the maneuver happens at the beginning of the maneuver window (10Re
+
30 min) in order to comply with #1 the transition to housekeeping must
be
1h prior to the maneuver (10Re - 30min).

So we should expect to see this for all orbits where the perigee
maneuver
can be done at the start of the maneuver window.

All,
   I have a couple comments for the sign off. Battery Cell Balancing
Cycle
   7 is to close to the beginning of the science cycle. 10re Cmd check
   (House Keeping Mode) is ~32 minutes prior to 10re Desc crossing.
        Tim

   Battery Cell Balancing
   Step 5   Verify no charging cycle within 2 hours of ASCENDING or
      DECENDING macro execution
      Cycle # 7 will need to be removed

Guys,
    I forgot to comment out another MPS Generated command.
 DELETED: @ACT_SetSpinPulseProtectEnable Disable
$TIME=2011/07:18:15:19:41

  Here is V002 of the Orbit# 133 ATS

  Guys,
       Here are the planning files for Orbit# 133.
  Approvals/comments are needed by COB Friday 8 July 11.
  I have also included the Battery Balanng ATS that will be uploaded 13
  July 11

  Gain Test Commands loads for IBEX Hi and Lo will be generated and sent
  out once the final STF's have been approved.
