Our research team proposes solutions in terms of transmission architecture design and low layers of communication systems. Our objective is to improve the capacity, availability, and security of radio satellite links, and increase the technological maturity of optical transmission links. It sets in place:

• • Real-time digital demonstrators at the laboratory level by relying on rapid field-programmable gate array (FPGA) type digital processing technologies or system on chip (SoC)
  • Analog test benches for microwaves and microwave photonics

The growth of New Space with the emergence of massive constellations of low earth orbit satellites, as well as the evolution of 5G standardization, are two major evolutions pushing us to think again about the integration of satellites within telecommunication networks.

Our goal is to understand the interaction of satellite systems and ground networks and validate solutions of architectures, with the vision of a fusion of satellites within next-generation global networks. We aim at responding to this requirement by developing tools and resources grouped in platforms to evaluate the application of new digital terrestrial technologies to the space industry, diminishing the risk connected to their integration within the satellite systems. It is especially concerned with the application of virtualization and network programming technologies as well as AI-based resource allocation with next-generation systems that are interoperable with the new communication ecosystems (5G, IoT).

The integration of low-cost digital technologies onboard (satellite, aircraft...) with reliability control, opens the way to sophisticated processing (AI, security) as close as possible to the sensor (edge computing), for more autonomy. Thus, we propose and validate new applications around sensors (IR or visible cameras, LIDAR, temperature and mechanical strain sensors network) based on image processing algorithms, embedded AI or signal processing, for detection and decision purposes in various fields of space or aeronautics (knowledge of the environment, monitoring of systems, knowledge of the space situation). Whenever the benefit is justified, we propose to set up onboard or in orbit experiments for demonstration purposes.
