L-Band Satellite Decoders

A few small projects aimed at decoding various L-Band satellites

Dependencies

Some projects will require (or / and) :

The flowcharts require GNU Radio 3.8 or above.

FengYun-3 A/B/C

Supported downlink : AHRPT, 1704.5Mhz (3C 1701.4Mhz)
Modulation : QPSK
Symbolrate : 2.8Mbps (3C 2.6MSPS)
Recording bandwidth : >= 3MSPS, 6MSPS or so preferred

Decoding :

  • Record a baseband
  • Demodulate with the FY Demodulator flowchart
  • Process the soft symbols with FengYun Decoder (use 3b mode for 3c, seems like the coding was changed)
  • Use that file in MetFy3x or run it through the CADU RSynchroderand to continue
  • Run the resulting CADU file through the FengYun VIRR Decoder

MetOp A/B/C

Supported downlink : AHRPT, 1701.3Mhz
Modulation : QPSK
Symbolrate : 2.33Mbps
Recording bandwidth : >= 3MSPS, 6MSPS or so preferred

Decoding :

  • Record a baseband
  • Demodulate with the MetOp Demodulator flowchart
  • Process the soft symbols with MetOp Decoder
  • Use that file in MetFy3x or run it through the CADU RSynchroderand to continue
  • Run the resulting CADU file through the MetOp AVHRR Decoder
