First thing to do is updating the client, documented here.
If you run in to problems please check here for troubleshooting.
Make sure to investigate if files already exists, versions changed, you already have pre/post-scripts etc. I will not be responsible for any problems so be careful when following this guide!
Follow the instruction on https://gr-satellites.readthedocs.io/en/latest/installation.html
The latest gr-satellites >=3.7.0-git with the --udp_raw and --ignore_unknown_args is required.
Basically this, ymmv:
cd
sudo apt-get install swig liborc-0.4-0 python3-pip feh cmake
sudo pip3 install --upgrade construct requests
git clone -b maint-3.8 --depth=1 https://github.com/daniestevez/gr-satellites.git
cd gr-satellites
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig
cd
git clone --depth=1 https://github.com/daniestevez/ssdv
cd ssdv
make
sudo make install
A simple check to see if gr_satellites is working is by executing: gr_satellites --version
This should give an output similar to this (the version can be different):
gr_satellites v3.9.0-git

Clone this repo and enter it:
cd
git clone --depth=1 https://github.com/kng/satnogs_gr-satellites.git
cd satnogs_gr-satellites
sudo apt-get install jq
sudo make install
Make sure the individual programs work before you enable the automated process!
These are required: jq, gr_satellites, jy1sat_ssdv, ssdv, kiss_satnogs.py, find_samp_rate.py
Copy the grsat-wrapper.sh, kiss_satnogs.py, kiss_geoscan.py, find_samp_rate.py, satnogs-pre and satnogs-post to /usr/local/bin
sudo apt-get install jq
sudo cp grsat-wrapper.sh kiss_satnogs.py kiss_geoscan.py find_samp_rate.py satnogs-pre satnogs-post /usr/local/bin
sudo chmod 0755 /usr/local/bin/satnogs-post /usr/local/bin/satnogs-pre /usr/local/bin/grsat-wrapper.sh /usr/local/bin/kiss_satnogs.py /usr/local/bin/kiss_geoscan.py /usr/local/bin/find_samp_rate.py
The GNU Radio UDP source need to have memory buffer increased for receiving more than a ~48k stream, so will need to add the following:
sudo cp udp.conf /etc/gnuradio/conf.d/
In satnogs-setup; enable pre/post observation scripts under Advanced -> Scripts:
SATNOGS_PRE_OBSERVATION_SCRIPT = satnogs-pre {{ID}} {{FREQ}} {{TLE}} {{TIMESTAMP}} {{BAUD}} {{SCRIPT_NAME}}
SATNOGS_POST_OBSERVATION_SCRIPT = satnogs-post {{ID}} {{FREQ}} {{TLE}} {{TIMESTAMP}} {{BAUD}} {{SCRIPT_NAME}}
Under Advanced -> Radio settings:
UDP_DUMP_HOST = 127.0.0.1
This will enable the UDP output. Select Apply and exit.
Inside the script grsat-wrapper.sh there's some options. Make sure to edit the installed version.
# Settings
KEEPLOGS=no # yes = keep, all other = remove KSS LOG
# uncomment and populate SELECTED with space separated norad id's
# to selectively submit data to the network
# if it's unset it will send all KISS demoded data, with possible dupes
SELECTED="39444 44830 43803 42017 44832 40074"
Please note that enabling KEEPLOGS it will eventually fill up the filesystem, also these are by default stored in tmpfs and it means they will be removed at reboot.
It is also totally possible to add other demodulating software to the main script. Check the previous versions of the grsat-wrapper.sh to see some examples on how it worked in earlier releases.
Enter the repo and do a pull:
cd satnogs_gr-satellites
git pull
Then follow the install step again.
Note: reverting certain software with satnogs-client-ansible is not possible, for example going from experimental to stable is not supported.
Clear out the variables with satnogs-setup:
SATNOGS_PRE_OBSERVATION_SCRIPT
SATNOGS_POST_OBSERVATION_SCRIPT
UDP_DUMP_HOST
Then update + apply.
If you want to you can remove the scripts installed:
cd /usr/local/bin && sudo rm -f find_samp_rate.py grsat-wrapper.sh kiss_satnogs.py kiss_geoscan.py satnogs-post satnogs-pre
