• Historical evolution from single to distributed satellite systems

• Reconfigurability and responsiveness in space applications• Swarms and constellations of federated pico-satellites• Potential missions• Remote sensing federated mission• Infrastructure for the Moon Village• CubeSat mission for Moon exploration

Summary

Historical evolution 1/2

• Single-satellite, single-mission• NAVSTAR GPS – the first satellite system achieving their mission through the concurrent use of all satellites.• Globalstar• Iridium – Inter-satellite links started playing a determinant

role• Distributed satellite systems

Historical evolution 2/2

• Network-centric satellite systems

• Copernicus

• Galileo

• Federated satellite systems

Responsiveness

• Reconfigurable payloads

• Obsolescence problem• Simple payloads• Flexible payloads

• Reconfigurable + Flexible = Responsive

Constellations of FSS

• CubeSat

• Currently CubeSats and LEO satellites are designed as standalone systems

• Satellites with interconnecting capabilities

Remote sensing mission

• Three different CubeSats• Flying Camera 1• Flying Camera 2• Flying Server

• Communication with ground segment or GEO satellite• Scaling up to bigger satellites

Ground Segment

“Moon Village” 1/4

• Requirements• Planetary communications• Navigational infrastructure

• Architectures• Comprehensive, well-structured and forward looking• “ad hoc”, flexible, expandable architectures

“Moon Village” 2/4

• Can we use GNSS beyond Earth orbit and on the Moon?

“Moon Village” 3/4

• AEGIS NASA study• Lunar constellation withtwo Relays in high polarorbit at 10000km spaced

at 180⁰, and on a total of 18 Orbiters

“Moon Village” 4/4

• EASA study• Moon GNSS based on• EGNSS: Earth GNSS• MGNSS: GNSS satellites orbiting the Moon• MSB: Moon Surface Beacon

FSS for Moon exploration 1/2

• CubeSats can be used for space exploration.

• Federated CubeSats in Moon’s orbit will enable diverseapplications.• LunaH-Map

FSS for Moon exploration 2/2

• Constellations of CubeSatscan provide navigation, communication and observational compatibilities.• CubeSat Lunar Positioning System• Hybrid of multiple CubeSatsand two polar small satellites

Endurosat

• ECSS and NASA compliant and verified CubeSats• Up to 5X faster production and delivery• Designed as a multipurpose platform• Capability for mass production• Ideal test bed for new technologies

• Plan• Establish permanent space infrastructure by Interconnected satellites in orbit• Amplify the existing services and provide additional hybrid solutions for new customers

Conclusion

• Federated pico-satellites /CubeSats/ can be affordable and effective solution.

• Provide a test bench

• Federated CubeSats can provide a promising solution for planetary explorations.
