Standardisation is Key
Collaborative,continuous, industry led
standardisationof interfaces
More launch opportunities
More Missions
Larger selection of off-the-shelf subsystems

Conclusion
• CubeSats offer an exciting opportunity to put new technologies into space.
• The size and cost of CubeSats enable applications too costly to be implemented previously.
• CubeSat constellations are likely to be the killer APP for CubeSats.
