CENTRE NATIONAL D'ETUDES SPATIALES - CNES

Their core work

CNES is France's national space agency, responsible for designing, developing, and operating space systems — from launch vehicles and satellites to scientific instruments and ground infrastructure. Within H2020, CNES contributes deep expertise in Earth observation, space surveillance and tracking (SST), electric propulsion, and stratospheric balloon platforms for scientific research. They bridge the gap between space technology development and operational services, particularly in environmental monitoring via Copernicus and gravity-based Earth science. With EUR 36M in H2020 funding across 31 projects, they are a major institutional anchor for European space and Earth observation programmes.

What they specialise in

How they've shifted over time

In 2014–2018, CNES focused on space technology roadmapping, propulsion R&D (electric and nuclear), launch systems (ALTAIR), and early SST service establishment — essentially building the European space infrastructure baseline. From 2019 onward, the focus shifted decisively toward Earth observation applications, space weather, radiation resilience for electronics, and operational environmental services like Copernicus calibration and gravity-based groundwater monitoring. The trajectory shows a clear move from upstream technology development toward downstream operational services and applied Earth science.

CNES is shifting from building space infrastructure toward exploiting it for environmental monitoring, space situational awareness, and radiation-hardened electronics — making them increasingly relevant for climate and security applications.

How they like to work

CNES overwhelmingly participates rather than leads — coordinating only 1 of 31 projects (HEMERA), reflecting their role as a major institutional contributor that strengthens consortia with infrastructure, data, and domain authority rather than seeking to manage them. With 313 unique partners across 40 countries, they operate as a high-connectivity hub in European space research, open to broad collaboration. Their repeated presence in multi-phase programmes (EPIC→EPIC2, PERASPERA→PERASPERA-X, successive SST lines) shows they are a reliable long-term partner who stays committed across programme generations.

CNES has collaborated with 313 distinct partners across 40 countries, making them one of the most connected space actors in H2020. Their network spans all major EU member states plus international partners, with particularly dense connections in space and Earth observation communities.

What sets them apart

As France's national space agency, CNES brings institutional weight, operational infrastructure (launch sites, balloon facilities, ground stations), and decades of mission heritage that no university or SME can match. Their unique combination of SST operations, stratospheric balloon access, and Copernicus data expertise makes them a one-stop partner for projects needing both space assets and scientific analysis capability. For consortium builders, having CNES on board signals credibility to evaluators and guarantees access to real operational space infrastructure.

Highlights from their portfolio

• 2-3SST2018-20
  Largest single project at EUR 19.9M — a cornerstone of the European Space Surveillance and Tracking service, demonstrating CNES's central role in space domain awareness.
• HEMERA
  CNES's only coordinated H2020 project, providing transnational access to stratospheric balloon platforms — a unique research infrastructure capability few organizations worldwide can offer.
• GRACEFUL
  Combines magnetic field, gravity, and Earth rotation observations to probe deep Earth interior — showcasing CNES's ability to connect satellite data with fundamental geophysics.
