Each one links to its EU funding record and the partners it works with: a starting list for building a consortium.
The topic encompasses actions within the scope of the co-programmed European Partnership on Globally Competitive Space Systems (‘Space Partnership’) in the areas of satellite communication (SatCom), Earth Observation (EO) and New Commercial Space Transportation Solutions and is part of cohesive activities in the domain of digital developments under the grand heading of “digitalisation for commercial space solutions”.
Under the area of Using Space on Earth related to SatCom and EO, below this topic focus on the fast increment of the Low to Mid TRL level building blocks for key technologies required to strengthen competitiveness in these domains. Digitalisation is a major enabler for enhancing the value of an End-to-End EO and SatCom system. For example, processing applied to multi-sensor data can significantly enhance the resolution of the final data set, and digital optimisation of the data flow directly improves the End-to-End timeliness of an EO system (from request to delivery). Lastly, the enhancement of End-to-End data resilience and integrity calls for digital technologies on-board and, on the ground.
Project results are expected to contribute to one or several of the following expected outcomes:
This will contribute to developing, deploying global, more flexible and reactive space-based services applications, to contribute to fostering the EU's space sector competitiveness, as stated in the expected impact of this destination.
The areas of R&I, which needs to be addressed to tackle the above-mentioned expected outcomes are:
Proposals should address at least one of the areas outlined above.
Proposals are expected to promote cooperation between different actors (industry, SMEs and research institutions) and consider opportunities to quickly turn technological innovation into commercial use in space.
Proposals under this topic should explore synergies and be complementary to already funded actions in the context of technology development at component level, while still enabling new entrants and new approaches. In particular the topics: Critical Space Technologies for European non-dependence (HE H2020 SPACE-10-TEC-2018-2020, COMPET-1-2014-2015-2016-2017, HORIZON-CL4-2021-SPACE-01-81/ 2023-SPACE-01-72/ 2024-SPACE-01-73), satellite communication technologies (H2020 COMPET-2-2016, COMPET-3-2017, SPACE-15-TEC-2018, SPACE-29-TEC-2020, HORIZON-CL4-2021-SPACE-01-11), Earth Observation end-to-end technologies (HORIZON-CL4-2022-SPACE-01-13, HORIZON-CL4-2023-SPACE-01-11). It is expected that projects make use of existing European technologies and/or building blocks, including at component level, contributing to European non-dependence and strengthen competitiveness, and this should be clearly presented in the proposal. Furthermore, proposed activities should be complementary to H2020 and Horizon Europe funded projects, national activities and activities funded by the European Space Agency (ESA).
This topic implements the co-programmed European Partnership on ‘Globally Competitive Space Systems’ (GCSS). As such, projects resulting from this topic will be expected to report on results to the European Partnership ‘Globally Competitive Space Systems’ (GCSS) in support of the monitoring of its KPIs.
In this topic, the integration of the gender dimension (sex and gender analysis) in research and innovation content should be addressed only if relevant in relation to the objectives of the research effort.

Activities are expected to achieve TRL 4-5 by the end of the project. The reference TRL definition is the ISO 16290:2013 applicable to the space sector. Activities may start at any TRL.

Applicants asked the EU 1 questions about this call and the EU published the answers. They clarify the call documents but do not replace them.
Proposals are submitted and evaluated against the Work Programme topic expectations. In this sense, the TRL targets are very important elements and they must be in line with the type of action of the chosen topic.
For topic HORIZON-CL4-2025-02-SPACE-31, the core of the project activities are expected to be related to the target TRL4-5 as described in the Work Programme. It is not excluded that the proposal deviates from this target for some of the developments, but in such a case this must be thoroughly justified.
In case higher TRL activities (such as ground demonstrations on representative hardware or in-flight demonstrations) constitute a substantial part of the proposal, then the applicant should consider applying to topic HORIZON-CL4-2025-02-SPACE-32.
For the definition RIA vs IA activities, please refer to Regulation 2021/695 establishing Horizon Europe (Art 2. Definitions, items 32 and 33)
