Software-defined radio (SDR) and satellite reception toolkit — what to install, what you can hear from space, and how to compose the open-source stack (SatDump, SatNOGS, GNU Radio, rustradio, satkit). Covers hardware abstraction (SoapySDR, rtl-sdr-rs), DSP frameworks (GNU Radio, liquid-dsp, rustradio, radiorust), receiver UIs (SDR++, SDRangel, Gqrx, CubicSDR), satellite decoders (SatDump for NOAA APT, Meteor-M LRPT, GOES HRIT, Inmarsat), ground-station orchestration…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SDR & Satellite Reception

How to hear satellites with a $30 dongle, decode the bits, predict the next pass, and (if we want) wire it into Life Agent OS or Opsis as a real-world-event source.

## What this skill covers

The full open-source satellite reception stack, by layer:

| Layer | What it does | Pick |
|---|---|---|
| **L0** Hardware abstraction | One API across dongles | `SoapySDR`; pure-Rust `rtl-sdr-rs` |
| **L1** DSP framework | Demod, filter, sync | `GNU Radio` (standard), `liquid-dsp` (lean C), `rustradio` (Rust), `radiorust` (Tokio) |
| **L2** Receiver UI | Watch the spectrum, demod live | `SDR++`, `SDRangel`, `Gqrx`, `CubicSDR`, `SigDigger` |
| **L3** Satellite decoders | TLE-aware, multi-protocol | `SatDump` (90+ sats) |
| **L4** Ground-station orchestration | Schedule, rotate, Doppler | `SatNOGS`, `sgoudelis/ground-station` (2026), `Hamlib` |
| **L5** Orbit mechanics | TLE → pass times → az/el | `sgp4` (Python), `neuromorphicsystems/sgp4` (Rust), `satkit` (full astro) |

How to install

The exact contents, by fingerprint
mdr add broomva/skills/sdr-satellite@sha256:e7129251e5352629

The line at the top of this page pins the label git:20260628.9edbf07, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
