GNU Radio flowgraph for SUCHAI-4 telemetry decodingOverview
The DIY Nano-Groundstation is a VIME-funded (Vicerrectoría de Vinculación con el Medio, USACH) outreach and educational initiative aimed at bringing satellite tracking and radio telemetry reception to high school students to foster STEM learning.
By developing accessible, low-cost satellite groundstation kits built on open hardware and Software-Defined Radio (SDR) technology, the project empowers high school students and educators to construct their own satellite receivers, track active operational CubeSat missions in orbit (such as SUCHAI-4), and decode live telemetry and beacon data directly in the classroom.
Technical Details
- Open Hardware & Software-Defined Radio: Utilizes accessible, budget-friendly SDR dongles and custom antenna designs for receiving UHF satellite beacons.
- Satellite Beacon Decoding: Full pipeline integration for receiving, demodulating, and decoding FSK/GFSK telemetry packets from active CubeSats such as SUCHAI-4.
- Educational Hands-on Workshops: Interactive training sessions for high school teachers and students, covering satellite orbital mechanics, radio frequency fundamentals, and embedded signal processing.
