Flatsat 1 is a hardware-based training platform designed to be vulnerable — on purpose.
Flatsat 1 is designed to help you learn and prototype radio systems safely and legally while gaining real-world skills in RF communication, signal analysis, and protocol fuzzing. It’s built for hackers, engineers, and space enthusiasts who want to dive deep into space-grade systems, learn cybersecurity concepts, and prototype their own payloads.
What You Can Do With Flatsat 1:
Hands-on Learning – Use Flatsat 1 as the hardware companion to the PwnSat course from Electronic Cats, with structured lessons on binary exploitation, secure communication, reverse engineering, and space protocols.
Hack Real Vulnerabilities – Explore and exploit firmware designed to simulate real-world satellite systems and vulnerabilities. It’s a safe playground for learning and discovery.
Join the Mission CTF – Participate in space-themed capture-the-flag challenges that simulate real satellite operation scenarios. Your board becomes your spacecraft!
Prototype Your Payloads – Use the onboard components to develop and test your own payload logic, radio communication, or telemetry systems before launching bigger projects.
Flatsat 1 uses ISM (Industrial, Scientific, and Medical) band frequencies for all RF communication — typically 433 MHz or 915 MHz, depending on your region. These frequencies are internationally reserved for unlicensed, experimental, and educational use.
Flatsat 1 does not use sensitive or restricted space communication bands like X-band, Ka-band, or S-band. This ensures that Flatsat 1 does not interfere with any production space systems, licensed satellites, or critical ground infrastructure.
Onboard Components:
• RP2040 – Powerful MCU for comms and simulation.
• BME280 – Environmental sensor for telemetry testing.
• 2 x SX1262 – LoRa radios for realistic space-ground communication scenarios.
• Open Documentation – Github Wiki with Getting Started.
• LIS2DH – 3-axis accelerometer for sensor data emulation and tampering challenges.
• OpenHardware – Schematics and Firmware.
Train like a pro, without breaking the rules.
