Quantum Key Distribution (QKD) holds the promise of enabling provable secure communication. In today's efforts based on optical transmission, the challenge is to handle significant transmission losses. Complementary to fiber-based QKD with trusted nodes or quantum repeaters, satellite-based QKD systems [1] for large-distance communication are being developed. To this end, a European quantum satellite will be implemented, capable of secure quantum key exchange with a ground station. We present the project status and highlight some of the technical requirements to operate such a system under real-world conditions.
