Low-earth orbit (LEO) satellite constellations are a special type of cyber-physical systems. Their meteoric rise has led to the proposition of many novel use cases and applications. Recent research has also highlighted the broad and unique threat landscape afflicting LEO constellations. However, the CPS security community lacks an experimentation platform to thoroughly identify and explore attacks and their corresponding defenses. We report our experience in building such a platform and perform initial case studies.

*Subset of Starlink orbital planes (green lines). A possible ISL configuration for some satellites is shown (orange lines) in +grid: a Sat forms two links with its immediate neighbours in the same plane and two links to Sats in adjacent planes. Two GSs: São Paulo (gray), and Fortaleza (purple).
