This package provides GNUradio OOT modules and grc
flowgraphs that facilates Radio Astronomy Observations with software defined radio devices.
There are two flavors of this projects:
- NSF Integrate and Detect softwares that allow for HI measurements and also event detections from cosmic ray detections, developed by Dr. Glen Langston. See here and the lightwork memo series for more details.
- DSPIRA software developed for and by High School Teachers part of the NSF funded RET program called Digital Signal Processing in Radio Astronomy (DSPIRA) at WVU university from the summers of 2017 to 2021. For more details visit the webpage and the companion website called dspira-lessons that has lessons, guides and more material help one to use radio astronomy in a high school classroom. This material is designed by the High School teachers part of this program.
- Install GNUradio
-
- Install gnuradio external python dependencies and SDR drivers by typing the following and hit enter:
sudo apt install gnuradio gr-osmosdr airspy python3-h5py python3-ephem git cmake liborc-0.4-dev -y
- To clone the repository:
git clone https://github.com/WVURAIL/gr-radio_astro.git
- Switch to the gr-radio_astro directory:
cd gr-radio_astro
- Make a build directory:
mkdir build
, and then move to it:cd build
- Then run the following in the build directory:
cmake .. sudo make sudo make install
Additional Steps for setting the proper Python environment:
- Edit your
.bashrc
file and add this to the bottom to set Python path:export PYTHONPATH=/usr/local/lib/python3/dist-packages:/usr/local/lib/python3.10/dist-packages:$PYTHONPATH
- Additionally you can create appropriate symbolic links
- Check which python is the installed version of GNURadio by opening
gnuradio-companion
in a terminal window and click onHelp --> About
and noting the python version on the dialog box that opens. - Go to the following by typing:
cd /usr/local/lib/python3.10/dist-packages
orcd /usr/local/lib/python3.9/dist-packages
for the appropriate python version. - Type
ln -s /usr/local/lib/python3/dist-packages/radio_astro
- Check which python is the installed version of GNURadio by opening
