An Introduction to Cybersecurity in Space
summary
Claims that there are more satellites in the last three years than in the three decades prior and demonstrations using hack RF1 and lime SDR plus GNU Radio support concrete threat feasibility; examples include GNSS spoofing of 26 ships in the Black Sea, suspended flights at Tartu, the Viasat outage in 2022, DIY Yagi antennas overpowering uplinks, and Starlink laser links between satellites; mitigations cited are SDLS with AES 256 with Galloy counter mode, FHSS/DSS, angle‑of‑arrival, encryption, and beamforming.
