Towards dynamic real-time scheduling for multiple earth observation satellites

作者:

Highlights:

• Established a multi-objective dynamic scheduling model for real-time tasks.

• Proposed task dynamic merging and task “temporary” retraction strategies.

• Proposed DMTRH algorithm for dynamic real-time scheduling of multiple earth observation satellites.

• Made a trade-off between scheduling revenue, stability and energy conservation.

• Improved observation effectiveness and resource utilization of earth observation satellites.
