• 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.
