The 4S Symposium is the biennial ESA/CNES symposium on small satellite systems, missions and services. It invites original contributions on small satellites, CubeSats, satellite constellations and swarms, onboard computing, small satellite missions, space communications, VLEO and deep space. Submissions may take the form of full research papers, extended abstracts and poster presentations reporting theoretical, computational and experimental work, as well as industrial case studies and applications. The meeting brings together researchers, engineers, industry practitioners and students to exchange recent results and discuss emerging directions in the field. Accepted papers are published in the conference proceedings (European Space Agency (ESA)).
