Simulated Satellite Communications on Raspberry Pi
Walks through building a CubeSat Simulator Lite using a Raspberry Pi and software-defined radio to transmit mock satellite telemetry.
Summary
Hands-On Satellite Hardware Simulation
The CubeSat Simulator Lite project provides an accessible entry point into aerospace cybersecurity by emulating the digital and RF subsystems of an operational nanosatellite.
Building the Raspberry Pi Ground Node
The workshop setup configures a Raspberry Pi single-board computer running dedicated software packages to generate sensor telemetry, including battery voltage, temperature, and simulated altitude data.
Transmitting and Decoding Satellite Signals
Attaching a small antenna to the Pi allows it to broadcast digital telemetry frames over amateur radio bands, which participants capture and demodulate using software-defined radios.
Educational Applications in Aerospace Security
Simulating small satellite payloads provides security researchers with a safe, repeatable hardware environment to study telemetry formatting, frame encoding, and space communication link vulnerabilities.
