Phi-Sat-1 at Low Earth Orbit (Tiangong Space Station)

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 the Phi-Sat-1 deployment at Low Earth Orbit (Tiangong Space Station)?
Phi-Sat-1, built by European Space Agency, is recorded as a deployment at Low Earth Orbit (Tiangong Space Station) on the DEPLOY registry. European Space Agency operates the deployment directly.
Who operates Phi-Sat-1 at Low Earth Orbit (Tiangong Space Station)?
European Space Agency, the manufacturer of Phi-Sat-1, operates this deployment directly. This is a maker-deploys-its-own-product arrangement rather than a customer pilot.
When did the Phi-Sat-1 deployment at Low Earth Orbit (Tiangong Space Station) go live?
The deployment is recorded as starting September 3, 2020 on the DEPLOY registry. Earlier activity may exist but is not yet sourced.
Is the Phi-Sat-1 deployment at Low Earth Orbit (Tiangong Space Station) still active?
As of the most recent verification on the DEPLOY registry, this deployment is no longer operating at this location.
Have there been incidents at the Phi-Sat-1 deployment at Low Earth Orbit (Tiangong Space Station)?
No active incidents affecting this deployment are recorded on the DEPLOY registry. Absence of recorded incidents is not a guarantee no incident occurred; DEPLOY records only sourced incidents and suppresses retracted ones.
