Cycle 15 LRP Construction and
Characteristics
July 21, 2006
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.

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)

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-SAAfree per day.
Even with optimistic
“validation”, the
winter is 130-300
orbits oversubscribed.

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).

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.
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.
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.
