There are several tools available to decode telemetry and packets. SatNOGS provides some built-in demodulators for various data formats. There are also additional tools that allow you the decoding of telemetry.

Built-in demodulators

Although the SatNOGS servers support many satellites with many modes, only the following modes are supported with built-in demodulators:

  • APT (Automatic Picture Transmission)
  • AFSK 1k2 (Audio Frequency Shift Keying)
  • CW (Continuous Wave, Morse Code)
  • DUV (Data Under Voice)
  • GFSK 9k6 (Gaussian Frequency Shift Keying)
  • FSK 9k6 (Frequency Shift Keying)
  • LRPT (Low Resolution Picture Transmission)

SoX - Sound eXchange

SoX is the Swiss Army knife of sound processing programs. SoX is cross-platform and is available for many operating systems (Windows, Linux, MacOS X, etc.).

SoX supports demodulating the following modes:

  • CW (Continuous Wave, Morse Code)

Fldigi in audio playback mode

Fldigi can be used to decode a variety of data modes.

  • CW (Continuous Wave, Morse Code)

FoxTelem for FOX1 series satellites

FoxTelem currently supports decoding DUV telemetry the following satellites:

  • AO-85 (Fox-1A)
  • AO-91 (Radfxsat / Fox1-B)
  • AO-92 (Fox1-D)
  • Fox-1Cliff, and
  • Fox-1E.
