Raspberry Pi satellite SDR base station for weather & telemetry.

Supported satellites

Edit persistent-data/config/station.config to configure your ground station.

Edit persistent-data/config/sats.list and persistent-data/config/sources.list to configure satellites and TLE sources.

Run ./app.sh radio tlesync to pull fresh TLE data from the internet.

Run ./app.sh build to build and ./app.sh up to run the full stack.

Radio stack

- importer: Imports IQ files recorded by other tools (e.g. SDR#)
  - SDR#
  - SDR# IF Recorder
- decoder: Decodes a saved signal into usable data (weather maps or telemetry dumps)
  - SatNOGS GNU Radio Blocks
  - libFEC
  - TUM WARR closed source assets
- scheduler:
  - PyEphem
  - Skyfield
- tlesync: Loads the newest TLEs from the internet
