Radiosonde M10

Tools for decoding M10 radiosonde signals.

Files

• m10ptu.c - M10 decoder (trimble GPS)
  m10gtop.c - (new) M10 (Gtop GPS)

  Compile

  gcc m10ptu.c -lm -o m10ptu
gcc m10gtop.c -lm -o m10gtop

  Usage

  ./m10ptu [options] <audio.wav>
  

  • <audio.wav>: FM-demodulated signal, recorded as wav audio file
    
  • options:
    -r: output raw data
    -v, -vv: additional data/info (velocities, SN, checksum)
    -c: colored output
    -b, -b2: integrate rawbit-/bit-samples
    

  Examples

  • ./m10ptu -v 20150701_402MHz.wav
./m10ptu -vv -c 20150701_402MHz.wav
./m10ptu -r -v -c 20150701_402MHz.wav
sox 20150701_402MHz.wav -t wav - lowpass 6000 2>/dev/null | ./m10ptu -vv -c
sox 20150701_402MHz.wav -t wav - highpass 20 2>/dev/null | ./m10ptu -vv -c
./m10ptu -b2 -vv -c 20150701_402MHz.wav
    

  If the signal quality is low and (default) zero-crossing-demod is used, a lowpass filter is recommended. If sample rate is high and timing/sync is not an issue, try integrating the bit-samples (option -b2).
