XXM RBOT Constraints
• 15c.The combination of multi-axis rolls and other (for example, ORS) science activities is restricted during apoapse
segments such that no more that two of the following three items shall be included in any one apoapse period (outside 20
Rs) [Constraint]:
- i.
Downlink rolls (e.g., rolls about z) and other science pointing activities where the Neg-Z to Earth angle is
less than 15 degrees
- i.i.
MAG_cal/CAPS rolls (e.g., rolls about x)
- i.i.i.
Pointing changes for other science (e.g., ORS) activities that share a common pointing. “Common”
pointing is defined such that each observation does not turn the spacecraft by more than +/- 15 degrees from other
“like” activities. A total 30-degree wide cone may also be acceptable but note that this is not to be interpreted as +/30 degrees as a 60-degree cone between activities is too great to be considered “common” pointing. The
expectation is that the secondary axis should not change during this period of observation.
- Note: other science pointing activities cannot all be joined into one group (in this “choose two out of three” rule) if
the activities do not have similar attitudes.
• 15k. [Constraint] When tracking a body for more than 60 degrees, an observation must either be:
- i. Less than 3 hours in duration, or
- ii. Broken into chunks of three hours or less with an inertially fixed quiescent break (~20 minutes at an inertial
attitude) between chunks for rotation of the secondary axis.
