Votre quotidien

Le site de Toulouse Champollion regroupe les activités de l’ingénierie de systèmes satellites, de la conception et réalisation de charges utiles, du développement et la qualification de segments sol, il intègre un centre de recherche et un accélérateur industriel de start-up et ventures ainsi que les activités dédiées à la science des basses températures, plus précisément au développement et à la production de refroidisseurs micromécaniques pour des marchés exigeants.

In-orbit assembly and manufacturing (ISAM) of large antennas are critical for advancing next-generation space capabilities because they overcome the size and launch constraints of current rockets. Building and deploying large, high-precision antennas directly in space enables the creation of structures far larger and more sensitive than those that can be stowed within a launch fairing, dramatically improving communication bandwidth or Earth observation resolution.

This approach also allows for modular upgrades, on-orbit repairs, and adaptive reconfiguration, ultimately reducing long-term mission costs and extending the operational lifespan of space infrastructure. Several open challenges remain in advancing ISAM of large antennas. One key issue is the design of suitable building blocks for ISAM reflectors, including the optimization of their dimensions and geometry to enable efficient assembly patterns.

Trade-offs may include a simpler antenna configuration with compensation at the feed array. In-orbit calibration also remains a critical technical challenge, particularly in case when the antenna is fed by an active array.

Radio Resource Management (RRM) could be exploited to maximize the capacity of the system based on the real beams characteristics produced by the geometry of the reflector.

The project will include the following core activities:

1. Define and investigate a scenario of a large ISAM reflector antenna in terms of its architecture and assembly

2. Co-develop manufacturing, radio frequency, digital techniques as well as RRM methodologies to optimise the trade-off between complexity cost and performance

Research field:

• Electrical engineering

• RF/Antenna engineering

• Aerospace engineering

• Telecommunications

Required skills:

• Electromagnetics

• Antenna modelling and design

• Antenna arrays and beamforming

• Experience with programming (Matlab)

The Thesis will include 18 months at Thales Alenia Space in Toulouse, followed by 18 months at the Heriot-Watt University, United Kingdom, Edinburgh . In total the PhD will span 36 months

Thales, entreprise Handi-Engagée, reconnait tous les talents. La diversité est notre meilleur atout. Postulez et rejoignez nous !
