Overview

Phi-Sat-1 (ɸ-Sat-1), launched September 2020 on the Vega rocket, is ESA's first satellite to demonstrate artificial intelligence for Earth observation. A 6U CubeSat in the FSSCat mission, it uses on-board AI to filter cloud-covered images before transmission to ground stations, reducing bandwidth requirements. The AI processing was developed in collaboration with Ubotica and demonstrates ESA's technology roadmap for edge AI in space.

Common questions

What is Phi-Sat-1?
Phi-Sat-1 (ɸ-Sat-1), launched September 2020 on the Vega rocket, is ESA's first satellite to demonstrate artificial intelligence for Earth observation. A 6U CubeSat in the FSSCat mission, it uses on-board AI to filter cloud-covered images before transmission to ground stations, reducing bandwidth requirements. The AI processing was developed in collaboration with Ubotica and demonstrates ESA's technology roadmap for edge AI in space.
How much does Phi-Sat-1 cost?
Phi-Sat-1's price is not publicly disclosed. DEPLOY has no verified price on record for Phi-Sat-1 from European Space Agency. Physical-AI systems like this are often sold through enterprise contracts or operated as a service rather than at a public list price; check the manufacturer for the latest.
Is Phi-Sat-1 actually deployed in the real world?
Yes. Phi-Sat-1 is independently verified in real-world operation on the DEPLOY registry, confirmed at named deployment sites with primary sources: not a concept, render, or demo-only.
Who makes Phi-Sat-1?
Phi-Sat-1 is made by European Space Agency, based in Paris, France (HQ); ESTEC Noordwijk, Netherlands; ESOC Darmstadt, Germany; ESRIN Frascati, Italy, founded in 1975.
Where is Phi-Sat-1 deployed?
1 verified deployment of Phi-Sat-1 is on the DEPLOY registry, including at Low Earth Orbit (Tiangong Space Station).
