Description du projet
Des mesures de haute précision de la gravité depuis l’espace
Les accéléromètres atomiques représentent une technologie avancée qui permet de mesurer le champ de gravité de la Terre. L’utilisation de cette technologie quantique dans l’espace améliorera considérablement les performances des missions de recherche climatique en offrant des mesures plus précises du champ de gravité à l’échelle mondiale. La validation de ces types de capteurs soulève toutefois de nombreuses questions liées aux niveaux de maturité technologique (TRL) de leurs sous-systèmes. Le projet CARIOQA-PMP, financé par l’UE, entend faire passer le TRL des sous-systèmes critiques au niveau 5. L’industrie et les instituts de recherche collaboreront afin de bâtir un modèle technique d’accéléromètre destiné à une mission d’exploration de la gravimétrie spatiale quantique.
Objectif
The overarching goal of CARIOQA-PMP is to prepare the deployment of quantum gravimeters/accelerometers in space, within the decade, through a Quantum Pathfinder Mission. Indeed, the emergence of quantum sensors offers an opportunity to provide new applications for climate sciences through the improvement of space gravimetry performance. Hence, the mastery of this technology in space is one of the major environmental, technological and strategic challenges of the decade. Three main objectives have been set for the scope and duration of CARIOQA-PMP:
1. To develop an Engineering Model (EM) of the mission’s instrument and to increase the TRL of the critical subsystems up to 5. Complementary EU industrial partners develop the subsystems of the instrument (i.e. Physics Package, Laser System, Microwave Source and Ground Support Equipment) and increase its TRL by assessing the critical technologies in relevant environments. Excellent institutes bring their quantum expertise for the definition of the EM and the mastering of its performance
2. To guarantee the adequacy of the hardware development with the future scientific needs. Through their knowledge of scientific applications, leading institutes in geodesy analyse and simulate potential mission scenarios for the Quantum Pathfinder Mission and future Post-Pathfinder scientific missions
3. To establish a technical and programmatic roadmap for Quantum Space Gravimetry Missions. This roadmap will be shared and validated by European stakeholders. It ensures the impact maximisation of the project’s results through its harmonisation with the European programmatic framework
CARIOQA-PMP brings together the main players of quantum sensors in Europe. It gathers unique skills among 16 partners from 5 EU Member States including 2 space agencies, 8 research organisations and 6 industries. As a result, CARIOQA-PMP will secure the capacities for implementing quantum gravimeters/accelerometers in space within the EU, contributing to the EU's strategic goal of non-dependence and autonomy.
