... Operations of the Hubble Space Telescope (HST) require the creation of stable and efficient observation schedules in an environment where inputs to the plan can change daily. ... A process and software architecture is presented which achieves stable and efficient observation schedules by dividing the task into long term and short term components. ... However, the resulting long range plan would be unstable as unscheduled observations in a week bin would have to be rescheduled. ...

... A 56-day long term plan is created using the least commitment SPIKE planning system with a resolution of 1 day 2. ... The SPIKE scheduler assigns resources evenly over plan windows based on user constraints such as sun and moon avoidance, guide star restrictions, and earth occultation. ... The long term schedule tracks 2 resources: 1. ... Five resources related to how orbits are affected by the South Atlantic Anomaly (SAA) The long term scheduler keeps track of orbits that are impacted by the SAA. ...

... Operations of the Hubble Space Telescope (HST) require the creation of stable and e#cient observation schedules in an environment where inputs to the plan can change daily. A process and architecture is presented which supports the creation of e#cient and stable plans by dividing scheduling into long term and short term components. ... The short term scheduler builds e#cient week long observation schedules by selecting observations which have plan windows open within the week. ...
