New funding call: Quantum Space Gravimetry Phase-B study & Technology Maturation

Deadline: 21 March, 2024 5:00 pm

Expected outcome:

  • Support the EU space policy and the EU Green Deal by providing the detailed definition of a quantum space gravimetry (QSG) pathfinder mission
  • Ensure EU sovereignty and non-dependence for the development of capacities leading to the availability of quantum space gravimetry
  • Enhance the TRL of the critical components necessary to build quantum gravimetry for space

These outcomes will contribute to securing the autonomy of supply for critical technologies and equipment, and fostering the EU’s space sector competitiveness, in line with the Expected Impact of the destination.

One proposal for this Phase-B study and the associated technology maturation will be selected.


The final objective of this call is to prepare the next phases of the implementation of a Quantum Space Gravimetry pathfinder mission. To achieve this objective, one proposal for a phase B study, as specified in ECSS‐M‐ST‐10C, leading to a preliminary definition of a quantum space gravimetry pathfinder mission, will be selected. This activity will cover both the quantum space gravimetry payload and satellite platform. This activity will also include the implementation measures that will enhance the technological readiness of the critical components leading to TRL 6/7 at the end of the project. The proposals will detail the reviews organised under the study. These reviews, organised by the consortium, will be open to COM and ESA experts. The Phase B will conclude with a Preliminary Design Review.

The goals of the quantum space gravimetry (QSG) pathfinder mission are:

  1. to consolidate the leadership of the European Union know-how in Quantum Sensing for Space and
  2. to demonstrate key technologies, their viability and related performances.

Necessary for the later deployment of a full QSG mission (e.g. BEC technology, rotation compensation, etc.), and pave the way to future space-based applications and services enabled by its data.

The focus of the QSG pathfinder mission shall be on the operation of a complete quantum accelerometer system and the detailed characterization of its performance in space. The results of the pathfinder mission, demonstrating the European Union capabilities and validating the technology, shall enable the development of ultra-sensitive sensors for an ambitious post-pathfinder QSG mission in the next step.

The QSG pathfinder mission shall be launched within this decade, paving the way for the deployment of an EU QSG mission within the next decade. The technology developed shall foster the EU non-dependence and leadership in this domain.

Deadline date: 21 March 2024 17:00:00 Brussels time.
