Start AIS-catcher on PlutoSDR #323

Open dendyKP opened 1 week ago

dendyKP commented 1 week ago

Hello! Please tell me how to run AIS-Catcher on Windows using the PlutoSDR board? It can be seen that PlutoSDR is not directly supported. But it is possible to run using SoapySDR. How do I do this on Windows? Sincerely, dendyKP.

jvde-github commented 1 week ago

hello! many thanks for reaching out.

The executable I build does not contain SoapySDR support (neither on Windows nor on Linux). I have not tried to build it with Soapy on Windows. I might give it a try some day.

Perhaps you can pipe the radio SDR data into AIS-catcher with something like:

SoapySDRUtil.exe --rate=1536000 --freq=162e6 --gain=32 --channels=0 --format=float32 - | AIS-catcher.exe -r cf32 . -s 1536000 -v

Thank you very much for your answer! Tried the command you suggested. It didn't work for me. SoapySDRUtil does not have frequency, gain or format options. Here is the entry from cmd: SoapySDRUtil.exe --rate=1536000 --freq=162e6 --gain=32 --channels=0 --format=float32 --direction=rx - | "AIS-catcher.x64/AIS-catcher.exe" -r cf32 . -s 1536000 -v SoapySDRUtil.exe: unknown option -- freq=162e6 SoapySDRUtil.exe: unknown option -- gain=32 SoapySDRUtil.exe: unknown option -- format=float32 AIS-catcher (build Aug 10 2024) v0.59-371-g3c362556 (C) Copyright 2021-2024 jvde-github and other contributors This is free software; see the source for copying conditions.There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. ←[1m←[33m[WARNING] SoapyVOLKConverters: no VOLK config file found.

I looked closer at the windows distribution and noticed there is a rx_sdr utility as well that I could make work with the RTL-SDR:

./rx_sdr -f 162000000 -s 1536000 -d driver=rtlsdr -F cf32 -g 32 - | AIS-catcher -r cf32 . -v -s 1536000

You need to properly set the gain, sample rate (twice, once for AIS-catcher and once for rx_sdr) and the driver. But this might be worth a try....

So, if you would write the radio data to a file, would that work? E.g.:

rx_sdr -f 162000000 -s 1536000 -F cf32 -g 70 data.raw

and then separately read it in for AIS decoding

 "AIS-catcher.x64/AIS-catcher" -r cf32 data.raw -v -s 1536000

ps I tried to build a version for Windows with SoapySDR, but difficult to get it stable and work on all Windows machines (note that for Linux, if you install the software is build on the device, for Windows we have pre-compiled everything which increases compatibility potential issues)
