Delfi-PQ: next level in satellite miniaturisation

Themes: Aerospace, High Tech


A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

Delfi-PQ is the next level in satellite miniaturisation: it's eight times smaller than its predecessors Delfi-C3 and Delfi-n3Xt . It functions as platform for technology demonstration and hands-on education.


Miniaturisation of space technology and distributed space systems are key research themes driving the development of Delfi satellites. Miniaturisation is beneficial because of cheaper launches, more potential payload volume and the ability to be applied as swarm or large constellation.


Delfi-C3 was launched in 2008 and Delfi-n3Xt in 2013. Delfi-PQ will be developed iteratively and expected to be launched in 2018. From there onwards, annual launches of Delfi satellites are foreseen.
