Reverse Engineering Satellite Communication
summary
Reverse engineers the GOES protocol and shows a working pipeline that captures 1.6 GHz C‑band signals with a dish, digitizes them with low‑cost SDRs (e.g. RTL‑SDR (3.2 MS/s) or LimeSDR (61.44 MS/s)), processes samples in GNU Radio and Go, and decodes image frames and telemetry. Provides recorded IQ files, an open source Golang helper app and documentation called GOES Satellite Hunt, and demonstrates decoded visible and thermal images from live captures, proving the method works.
