💰 Funding Details

Funding Description – HORIZON-CL4-2025-02-SPACE-32


Purpose of the Call

The call supports mid- to high-TRL (5-8) demonstration missions that digitally integrate Earth Observation (EO) and Satellite Communication (SatCom) capabilities. Projects must accelerate EU industrial competitiveness, strategic autonomy and non-dependence in these domains.


Financial Scheme

* Action type: Innovation Action (IA) – Lump-Sum Model (HORIZON-AG-LS)

* EU co-funding rate: 70 % for for-profit entities, 100 % for non-profit organisations (the lump-sum is calculated on this basis).

* Maximum EU contribution per grant: €18 000 000.

* Number of grants expected: 3–5 (subject to budget split among the three R&I areas).

* Payment profile: pre-financing at Grant Agreement Signature (GAS); interim payment(s) and balance linked to completion of work packages and acceptance of lump-sum reporting – no cost reporting is required, only achievement of verifiable milestones & deliverables.


What Is Funded

1. End-to-End SatCom mission capabilities (e.g. optical ISLs, 5G/6G integration, digital payloads, reconfigurable network nodes, modular testbeds).

2. On-board/ground digitalisation for EO (e.g. AI/ML edge processors, multi-spectral/-band imaging chains, data-flow optimisation, ground-segment standardisation, fusion analytics).

3. Synergetic building blocks common to EO & SatCom (e.g. cyber-secure architectures, RISC-V processing platforms, flexible downlink, resource-sharing tools, environment & sustainability metrics).


Activities must target at least TRL 6 in a relevant environment or in-orbit demonstration by the end of the project. Procurement of launch, hosted payloads, or aggregated IOD opportunities is eligible.


Eligible Participants & Consortia

* Minimum: 3 independent legal entities from 3 different EU Member States or Horizon Europe Associated Countries, each established in a Member State/AC.

* Combination of industry (large & SMEs), research organisations and academia is strongly recommended.

* Security restrictions: beneficiaries handling secure communications infrastructure must be established in an EU Member State and controlled by EU/EEA natural or legal persons (Article 22(5) HE Regulation).

* If EO/PNT data are used, Copernicus and/or Galileo/EGNOS services are mandatory (others can be complementary).


Key Dates

* Call opening: 22 May 2025

* Proposal deadline: 25 September 2025 – 17:00 (Brussels)

* Evaluation results: ≈ January 2026

* Grant Agreement signature (GAS): ≈ April 2026

* Project duration: 36–48 months recommended.


Complementarity & Synergies

Projects must demonstrate complementarity with previous FP7/H2020/Horizon Europe and ESA activities, and contribute to the GCSS Partnership KPIs. Re-use of European technologies/building blocks is expected.

🇪🇺 Strategic Advantages

EU-Wide Advantages and Opportunities for HORIZON-CL4-2025-02-SPACE-32


1. Single Market Access (450 + million citizens, 23 million firms)

Border-free commercial roll-out of EO/SatCom services (e.g. pan-EU connectivity packages, near-real-time EO analytics) without customs or roaming barriers.

Unified public-procurement pool – access to large contracting entities (EC, ESA, EUSPA, EMSA, Frontex, national civil-protection agencies) that buy space-enabled services for climate, security and infrastructure monitoring.

Data-reuse rights under the Open Data Directive facilitate secondary markets for value-added products from Copernicus and forthcoming IRIS² secure connectivity.


2. Cross-Border Collaboration & Knowledge Exchange

• Obligation to create consortia spanning ≥3 Member/Associated States stimulates technology co-development and risk-sharing.

• Access to 75 000+ space researchers in ESA, EUSPA, EC Joint Research Centre, EuroHPC, CERN-Ideasquare, etc.

• Easier staff mobility via Erasmus+ doctoral networks and Marie-Skłodowska-Curie post-docs embeds expertise rapidly across borders.


3. Alignment with EU Strategies

European Green Deal & Mission Adaptation to Climate: onboard AI for EO accelerates climate-risk indicators, supporting EU taxonomy & Fit-for-55 reporting.

Digital Decade – 5G/6G deployment: topic explicitly funds SatCom-NTN integration, underpinning 100 % gigabit coverage goal by 2030.

STEP & Chips Act: encourages RISC-V/open-HW payload processors, lowering non-EU dependencies and supporting EU semiconductor sovereignty.


4. Regulatory Harmonisation Advantages

Single Telecoms Rulebook & 5G/6G standards (ETSI, 3GPP Release-19/20): project outputs can be certified once and marketed EU-wide.

EU Space Law (forthcoming) & SST/STM framework: common licensing and debris-mitigation rules reduce legal friction for in-orbit demos.

GDPR uniformity simplifies pan-EU EO data pipelines by providing one compliance regime for personal-data-sensitive imagery.


5. Pan-European Innovation Ecosystem

• Synergies with ESA Φ-labs, Copernicus DIAS, EuroHPC supercomputers, 29 ESA BICs, 470+ EIT Digital nodes.

CASSINI Hackathons & Accelerators provide feeder SMEs ready to pilot EO/AI apps on the consortium’s testbeds.

• Access to standardised IOD/IOV flight tickets (e.g., ESA’s LEO rideshares, INNOSPACE) to validate payloads at reduced cost.


6. Funding & Blending Opportunities

Cascade-funding vouchers from DIGITAL-EUROPE (e.g., Space Data for AI) can sponsor start-ups to exploit consortium results.

InvestEU Space window & EIB Space Finance enable follow-on debt/equity for post-grant scale-up.

Connecting Europe Facility 2 (CEF-2 Digital) can co-finance ground segment cross-border fibre/teleport links required by the project.

• Cohesion-policy Smart Specialisation funds allow regional clusters (e.g., Basque NewSpace, Lazio SpacePark) to adopt project tech.


7. Scale & Impact Potential

EU-level demonstrator status fast-tracks standard adoption in 27 markets, amplifying TRL-8/9 validation into commercial contracts.

• Ability to bundle Copernicus, Galileo and IRIS² datasets delivers unique multi-constellation services difficult to replicate nationally.

• Supports resilient dual-use capabilities valued by both civilian agencies and EU Defence Fund programmes, enlarging demand base.


8. Strategic Autonomy & Non-Dependence

• Strengthens domestic supply chains for optical inter-satellite terminals, edge-AI chips, quantum-ready cryptography, aligning with Observatory of Critical Technologies.

Lump-sum grant model speeds cash-flow to SMEs, reducing reliance on non-EU venture capital during development.


9. Gender & Diversity Leverage

• Horizon evaluation rewards concrete plans for ≥50 % female early-stage researchers and inclusive entrepreneurship, enhancing HR attractiveness EU-wide.


10. Actionable Tips for Applicants

Declare main area clearly (SatCom / EO / Synergetic) to benefit from balanced-portfolio rule – increases probability of selection.

Map complementarities with past projects (COMPET-2-2016, CL4-2023-SPACE-01-11, etc.) to prove added value and avoid duplication.

Integrate STEP KPI tracking (e.g., number of open-HW components validated) to ease partnership reporting.

Plan a cross-border pilot service (e.g., Baltic-to-Mediterranean 6G-NTN corridor) demonstrating EU-wide operability by 2027.

• Reserve budget line for standardisation participation (3GPP, CCSDS, ESA OSIP)—counts positively under “impact” criterion.


---

By exploiting these EU-level advantages, consortia can de-risk technology maturation, access unrivalled markets and position themselves as key enablers of Europe’s next-generation space infrastructure.
