Our Philosophy
• Involve L, M and D students at all stages of the projects.
• Prefer a “Make Slowly” to a “Buy Quickly” approach
• Do something useful for citizens
• Collaborate with International academic and industrial partners.

Tomorrow A technology platform in a dedicated building
(opening in December 2015) Partner companies moving in to create a unique
cluster and a full workflow A synergy between Education, research and
industry A driver for innovation

• 1U CubeSat: MTCube Memory Test CubeSat
• Mission: characterize the SEE sensitivity of COTS memories in real space environment and compare with results of ground based radiation tests.
• But also: address the question of test validity
• Partners: – CSU Montpellier-Nîmes (Université Montpellier 2)– Van Allen Foundation– ESA– LIRMM– RADIAC research group of Université Montpellier 2

The Méditerranée Project
The south of France is constantly under the threat of large scale floodings due to sudden thunderstorms
Forecast accuracy may be significantly improved if data collected over Mediterranean Sea could be taken into account within 90 minutes after measurement
The ROBUSTA-3A mission consists in collecting water vapour concentrations measured onboard cargos, storing and forwarding them to Mission Control Center and making them available to Meteo France.

Conclusion
• So far, U.of M CSU has launched the only French Cubeat and R1B will be the second one.
• By doing everything at home, we have learned a lot• We are eager to collaborate with international
academic partners– Student exchange– Common nanosatellite projects – Ground segments– Constellations
