FengYun-2 S-VISSR Sync + Counter Corrector

This is a simple program for fixing S-VISSR transport frames of FengYun-2 satellites. This allows you to get a good photo with a bad SNR together with SatDump

Using

At the moment, the corrector works well only with data for a full transmission session! Start recording 1-2 minutes before the transmission starts and stop recording after the transmission ends. Otherwise, the corrector may give a bad result. I will fix this issue soon...

  1. Place the FengYun-2_corrector.json file from the Pipelines folder of this repository into the Pipelines folder in the satdump folder.
  2. Start transport frame decoding via FengYun-2 S-VISSR (Egor UB1QBJ Sync + Counter Corrector). This will save the transport frames to the Live_output folder in the Satdump folder. (if you did not change this folder in the settings)

2 3. After receiving the file with S-VISSR transport frames, use the corrector. For Windows, you can use a simple launcher in the corrector folder. Otherwise, use this style of command to run:

FengYun2-Counter-Corrector.exe -i (--input) input_file.bin (fengyun_svissr.svissr) -o --output (fengyun_svissr.svissrcorrected)

or

python FengYun2-Counter-Corrector.py -i (--input) input_file.bin (fengyun_svissr.svissr) -o --output (fengyun_svissr.svissrcorrected)

Note! There must be no spaces in the paths to the input and output files!

  1. Open the received corrected data in Satdump with the parameters as in the screenshot: 3
  2. Get a good picture with a bad SNR! 4
