️ Indra Space – Leading the Next Generation of Space Systems

At Indra Space, we are on a mission to redefine the European space industry by delivering high-performance small satellite solutions for LEO missions. Our ambition? To become a leading company in end-to-end satellite systems, driving innovation in:
Position, Navigation & Timing (PNT)
Secure Communications
Earth Observation & ISR
Space Domain Awareness (SDA) and Space Traffic Management (STM)
Science & space exploration

As the Space Business Unit of Indra Group, we combine cutting-edge technology with a full value chain approach—from satellite design and integration to ground segment and operations. With the integration of Deimos and strategic participation in Hispasat and Hisdesat, we are scaling Europe’s space autonomy and contributing to flagship programs like IRIS², Galileo, EGNOS, and Copernicus.
