SSTV Testbed
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
Testbed for the satnogs PD120 decoder.
|
|
|
|
|
|
|
|
|
|
The flowgraphs in the repository are kept as close as possible to the PD120 observation flowgraph
|
|
|
|
|
in [gr-satnogs](https://gitlab.com/librespacefoundation/satnogs/gr-satnogs/).
|
|
|
|
|
The repo also contains some audio and IQ samoles to test the decoder.

Running the Tests
|
|
|
|
|
-----------------
|
|
|
|
|
1. Checkout the testbed repo
|
|
|
|
|
```
|
|
|
|
|
git clone git@gitlab.com:LongHairedHacker/sstv-testbed.git
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
2. Compile and setup gr-satnogs
|
|
|
|
|
```

|
|
|
|
|
git checkout sstv-decoder
|

|
|
|
cd gr-satnogs
|
|
|
|
|
mkdir build
|
|
|
|
|
cd build
|
|
|
|
|
cmake ..
|
|
|
|
|
sudo make install
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
3. Run the flowgraphs
|
|
|
|
|
```
|
|
|
|
|
cd sstv-testbed
|
|
|
|
|
./run_ogg_test.sh
|
|
|
|
|
./run_iq_test.sh
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
4. Check the results in the `output` folder
