  1. Cycle 15 LRP Construction and Characteristics July 21, 2006

  2. Planning the Cycle • HST executed ~73 est_orbits/wk during the 2-gyro period of Cycle 14. • On July 21, 2006, (the 219 calendar is beginning to build), 3730 orbits had plan windows past 06.219. • At 73 est_orbs/wk, this would imply 51 full weeks of planning 330 est_orbs of tail. • However there are ~ 500 orbits of unplanned visits, so the true tail is ~830 est_orbs. HOPR ~ 70 orbits DD ~ 70 orbits TOO ~200 orbits CAL ~175 orbits Approximate Unplanneds: > integ baselined-lrp 07.180 08.091 Summary integration report 275 days in date range [07.180 to 08.091) --Date Range- ___Orbs/D___ ___Free/D___ ___Hide/D___ ___E-Fr/D___ ___E-Hi/D___ ___Oflo/D___ 07.180 08.091 849.1 3.08 437.9 1.59 292.1 1.06 558.9 2.03 171.2 0.62 120.9 0.44

  4. An initial Cycle LRP Build with all possible packed prior to 07.267 • From 06.289-07.071, • Classical resources show: • 10.34 orbits/day, and • 8.34 effective-SAA-free / day • (5.5 explicit SAA-free/day) > integ res_C15B01T09L02.rpt 06.289 07.071 Summary integration report over 147 days in date range [06.289 to 07.071) --Date Range- ___Orbs/D___ ___Free/D___ ___Hide/D___ ___E-Fr/D___ ___E-Hi/D___ ___Oflo/D___ 06.289 07.071 1520.2 10.34 807.9 5.50 712.3 4.85 1239.3 8.43 280.8 1.91 431.3 2.93

  5. Validator also implied a problem on the initial ‘packed’ Cycle Build From 06.289-07.071, Classical resources show: 9.99 orbits/day and 6.84 effective-SAA-free per day. Even with optimistic “validation”, the winter is 130-300 orbits oversubscribed. > integ res_VC15B01T09L03.rpt 06.289 07.071 Summary integration report on resources over 147 days in date range [06.289 to 07.071) --Date Range- ___Orbs/D___ ___Free/D___ ___Hide/D___ ___E-Fr/D___ ___E-Hi/D___ ___Oflo/D___ 06.289 07.071 1469.0 9.99 841.0 5.72 628.0 4.27 1005.0 6.84 464.0 3.16 164.0 1.12

  6. After Correcting Winter Oversubscription • After de-oversubscribing the winter: • 8.91 est_orbs/day • 6.78 effective SAA-free est_orbs/day • (4.65 explicit SAA-free). > integ baselined-lrp 06.289 07.071 Summary integration report over 147 days in date range [06.289 to 07.071) --Date Range- ___Orbs/D___ ___Free/D___ ___Hide/D___ ___E-Fr/D___ ___E-Hi/D___ ___Oflo/D___ 06.289 07.071 1309.2 8.91 683.3 4.65 548.3 3.73 997.0 6.78 234.7 1.60 313.6 2.13

  7. Caveats about over-interpreting Validator results • Validator results must be taken in context. • Validator is not calibrated against SPSS scheduling, particularly against 2-gyro. • E.g.: • Degree of reliance upon SAA-friendly scheduling in SPSS is unknown, • Efficiency of SAA-free usage is unknown, • SPIKE has no knowledge of MAG-field slew issues, • No slew constraint in SPIKE, • Some SPIKE-SPSS orbital viewing issues are known.

  8. Validation at free=5/hider=4 These validation levels leave an orbit/day in the average free limits for the unplanned. No “margin” for saa-hiding. Should be taken in context of planning process and other validation runs.

  9. Validation at Free=5/Hide=3 These validation levels leave an orbit/day each in the average free & hider limits for the unplanned. Should be taken in context of planning process and other validation runs.
