1. 0 Travel Notes

  • Chapman Conference and AGU NCTS approvals have gone out

2.0 MMS Flight Dynamics and Ephemeris/Attitude

  • Phase 1A Sliding Science ROI: 
    • Steve Petrinec has produced an updated plan.  See three files:  Petrinec_slidingROI_Update_timelines_ph1aPetrinec_slidingROI_Update_xy_2015_0313_ph1a_fast_modePetrinec_slidingROI_Update_fast_mode_times_agse1 
    • The SOC has evaluated the Petrinec Update and, as a next step, provided a recommendation for implementation. POC is Pat Smith for this.
    • The attached plot is an extremely simplified schedule based on Steve's optimized orbits.  I took the midpoint in time of the optimized ROI, and expanded it so that the ROI duration equals the duration of the control ROI.  I updated it every 4 weeks on the orbit that would correspond to the beginning of our ATS load.  In the beginning and end of Phase1a this would push the ROI underneath 7RE where EIS and FPI ramp down voltages.  During these times I just kept the ROI as close to 7RE as possible without going underneath.  This results in the following schedule:
      Orbit     Date     ATS WK     Start Offset (Min)     End Offset (Min)
      179     9/7/15     37     -90     -90
      193     9/21/15     39     -80     -80
      207     10/5/15     41     -50     -50
      236     11/2/15     45     -20     -20
      264     11/30/15     49     5     5
      292     12/28/15     53     40     40
      320     1/25/16     5     85     85
      348     2/22/16     9     90     90
      Thanks,  -Patrick


    • All, Here is another plot, updating the offsets every two weeks using the optimal values for the middle day, rounded to the nearest minute.  If there is a preference to always encompass the entire optimal ROI I can do that instead by choosing the min/max offset for ROI entrance and exit respectively, instead of the values from the middle day.  Let me know how this looks and I can generate a table.  I would be happy to call into the science meeting tomorrow.  -Patrick
