Horizon Space: EO & SatCom Demonstration Missions
Funds €5–10M consortium projects that mature Earth observation and SatCom technology to flight readiness, ahead of real demonstration missions.
Horizon Space: EO & SatCom Demonstration Missions is a European Commission call that funds €5–10M consortium projects maturing Earth observation and satellite-communication technology to flight readiness, ahead of real demonstration missions. Europe’s Earth observation and satellite communication systems need to get smarter to stay competitive — more autonomous, more secure, and better at turning …
Mid-to-high TRL development of digital technology for Earth observation and satellite communication systems, aimed at getting it ready for real demonstration missions. In scope: end-to-end SatCom capabilities (secure services, satellites as network nodes, flexible RF payload testbeds, onboard signal processing), LEO/VLEO Earth observation equipment (real-time on-board processing, ground segment interoperability, multi-source data fusion), and technology shared across both — including a ‘tip and cue’ demonstration that links radio-frequency and EO sensors over inter-satellite links. Proposals may address more than one of these areas but have to clearly identify the single main one. Work covers on-ground testing in a relevant environment and, where flight is feasible, in-orbit software demonstration.
