Content

- Introduction - LEOP support - Routine operations

- Swath preview and ordering service - Semi-automated scheduling - Automated scheduling

- Time triggered scheduling - Event triggered scheduling

- Product delivery - Onboard Planning - Outlook


Tasks of Mission Planung Preparation Phase

- Understand desires of partners - Identify constraints - Develop workflows - Propose strategies for solving

conflicts - Develop interfaces with partners - Implement mission specific

planning system

Mission Planning connects multiple subsystems


Tasks of Mission Planung Operational Phase - Collect information - Create timelines - Derive tele-commands - Provide planning information

Mission Planning connects multiple subsystems

Onboard Planning VAMOS


VAMOS integrates onboard decisions based on real-time parameter evaluation with on-ground scheduling. It also allows adding further requests onboard.

- Reduce the margins of the planning model, enabling additional image requests





- Use onboard image analysis to generate additional image requests




- Use onboard image analysis to generate additional image requests

- Use commercial satellite network (OrbComm) to send additional image requests

Outlook

- Evolving the planning system to event triggered scheduling (Reactive Planning) - Realize resp. Extend interface to customer (preview, solution selection) - Implement Robust Commanding - Embed onboard decision mechanisms within ground based scheduling system - Evolve Mission Planning S/W libraries to components which may be selected and

configured mission specifically
