Hacking a Satellite Back to Life: The BEESAT-1 Resurrection
In 2013, Technische Universität Berlin's BEESAT-1 satellite stopped sending valid telemetry data. Projected to remain in orbit for another 20 years, its recovery would unlock new experiments. However, the satellite lacked both telemetry and software update capabilities. This talk recounts the story of how, by combining space and cybersecurity expertise, the fault was diagnosed without telemetry, software updates were implemented without the existing feature, and the satellite was resurrected in September 2024. The journey involved overcoming significant hurdles, including working with 15-year-old software and hardware and devising a method to upload new software without the standard update mechanism. The presentation details the entire recovery process, highlighting the unexpected challenges and successes.
