1st IAA LA Symp on Small Sat
Use of drone squadrons as a test bench for segmented-architecture
satellite missions

1st IAA LA Symp on Small Sat
Distributed Systems with Segmented Architecture
1st IAA LA Symp on Small Sat
SA attacks uncertainties●Technical Uncertainties: Failure of a component is
not a failure of the mission
●Environmental Uncertainties: More robust to object impacts or radiation levels
●Uncertainties of launch: Failures only affect to part of the mission.
●Demand uncertainties: Capabilities can adapt to demand.
●Requirements uncertainties: The mission can adapt to change in requirements.

SA advantages●Force multiplication: multiple modules
expand the area covered, increasing the science return of the mission.
●Simultaneous presence: some tasks require simultaneous presence and thus are impossible for any single spacecraft.
●System redundancy: if modules share capabilities, others can replace the role of a failed one.

The problem
●To develop, experiment with, and validate a Segmented Architecture-based system is expensive
1st IAA LA Symp on Small Sat
The proposal
●To create a tailored Control Center for UAV squadrons and use it as a tool for experimentation and validation Segmented Architecture-based satellite missions.
1st IAA LA Symp on Small Sat
Work Plan1. Develop a Control Center for UAV
Squadrons, with mission planning capabilities
2. Add to UAVs a Comm & Data Handling module to manage Temporary Scheduled Commands & Stored Telemetry
3. Add the concept of multiple stations
4. Add inter-UAV communications
5. Experiment!

Known Limitations
● Payload configuration
● Power (UAV battery vs Sat power supply)
● Flight mechanics
● Duration of the mission
1st IAA LA Symp on Small Sat
Conclusions
● Segmented Architecture satellite missions will be very important in the near future
● We propose a Multiple-UAV Control Center as test-bed for SA satellite missions
● A project to develop a m-UAV Ctrl Center is already underway
