Details

Expected Outcome:

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”. Digitalisation is a major enabler for enhancing the value of an End-to-End EO and SatCom system. Under the area of Using Space on Earth related to SatCom and EO, below this topic focusses on the Low to Mid TRL level developments of key technologies [1] required to strengthen competitiveness in these domains with a dedicated focus on synergies between Earth observation and Satellite telecommunication technologies. Projects are expected to contribute to one or several of the following outcomes:

  • Next generation Earth observation and SatCom payloads, technologies and processing means (on ground and in space);
  • Security of SatCom and EO services, supporting next-generation technologies for both ground and space commercial applications.

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.

Scope:

The areas of R&I, which needs to be addressed to tackle the above-mentioned expected outcomes are:

  • R&I on End-to-End SatCom Mission capabilities for increased robustness, energy efficient connectivity and compatibility with 5G & 6G waveforms such as constellation and network software management systems and optical communications, including both space and ground-based assets, and digital on-ground infrastructure to test and enhance operational efficiency;
  • R&I on building blocks and processes common to EO and SatCom systems allowing for in-orbit reconfigurability, faster data availability, on-board and on-ground smart computing and improved operation resilience.

Proposals are expected to promote cooperation between different actors (industry, SMEs, research institutions and infrastructures and academia) and consider opportunities to quickly turn technological innovation into commercial use in space. It is expected that projects make use of existing EU technologies and/or building blocks, including at component level, contributing to EU 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 contributes to the implementation of the European Partnership on ‘Globally Competitive Space Systems’ (GCSS). 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. null 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.

"> General conditions

1. Admissibility Conditions: Proposal page limit and layout

described in Annex A and Annex E of the Horizon Europe Work Programme General Annexes.

Proposal page limits and layout: described in Part B of the Application Form available in the Submission System.

2. Eligible Countries

described in Annex B of the Work Programme General Annexes. A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects. See the information in the Horizon Europe Programme Guide .

3. Other Eligible Conditions

If projects use satellite-based earth observation, positioning, navigation and/or related timing data and services, beneficiaries must make use of Copernicus and/or Galileo/EGNOS (other data and services may additionally be used).

In order to achieve the expected outcomes, and safeguard the Union’s strategic assets, interests, autonomy, and security, it is important to avoid a situation of technological dependency on a non-EU source, in a global context that requires the EU to take action to build on its strengths, and to carefully assess and address any strategic weaknesses, vulnerabilities and high-risk dependencies which put at risk the attainment of its ambitions. For this reason, participation is limited to legal entities established in Member States, Iceland and Norway and the following additional associated count

Context for bidders

We hold 353 notices from European Commission, going back to August 2026 — 350 of them still open. They buy mostly in Water & Environment, Forestry & Wildlife and IT & Telecom. There are 23 open space-satellite tenders in European Union. This one closes in 333 days.

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this space-satellite opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
