Integrating gr-satellites into SatNOGS

ve2dsk · December 7, 2023, 9:34pm

Hi,
about 1y installed, I didn’t remember if it’s from the source but from topic obtain here… (10/23/2022)
VE2DSK

$ gr_satellites --version
Traceback (most recent call last):
File “/usr/local/bin/gr_satellites”, line 16, in
import satellites.core
ModuleNotFoundError: No module named ‘satellites’

This means that gr-satellites is not correctly installed.

SA2KNG · December 7, 2023, 10:17pm

ok, built from source, and not set PYTHONPATH.
if already running the satnogs repos, just install it with apt sudo apt install gr-satellites.
make sure to remove the other install to avoid conflicts.

ve2dsk · December 7, 2023, 11:13pm

Many thanks for help…
I’ll reinstall… VE2DSK

ve2dsk · December 9, 2023, 10:42pm

Hi
gr_salellites Error came from line 16 and said “import satellites.core”

I found the problem…
After booting, if I manualy mention:
$ export PYTHONPATH=/usr/local/lib/python3/dist-packages/
The result is correct…

gr_satellites v3.15.0-git

Which file need this export precision…?

There are some good info here:

github.com

daniestevez/gr-satellites/blob/main/docs/source/installation.rst

.. _Installing from source:

Installing from source
======================

gr-satellites is a GNU Radio out-of-tree module, and can be installed as such,
by building it from source in a system where GNU Radio is already installed. The
general steps for installing gr-satellites from source include making sure that
all the dependencies are installed and then building and installing the
out-of-tree module.

Dependencies
^^^^^^^^^^^^

gr-satellites requires `GNU Radio`_ version at least 3.8. Depending on the GNU
Radio version, a different branch of gr-satellites should be used. See the
`gr-satellites README`_ for more information about the different branches.

I also got the ModuleNotFoundError: No module named ‘websocket’
Solved with:
sudo pip3 install websocket

PE0SAT · December 10, 2023, 1:15pm

Next time first look at the OS repository.

sudo apt-get update && sudo apt-cache search python3 | grep websocket

Command output:

ython3-django-websocket-redis - Websockets for Django applications using Redis (Python3 version)
python3-gevent-websocket - websocket library for the gevent networking library (Python 3)
python3-pyqt5.qtwebsockets - Python 3 bindings for Qt5's WebSockets module
python3-pyqt5.qtwebsockets-dbg - Python 3 bindings for Qt5's WebSockets module (debug extensions)
python3-pyside2.qtwebsockets - Python bindings for Qt5 WebSockets module (Python 3)
python3-gwebsockets - websocket server written in Python
python3-websockets - implementation of the WebSocket Protocol (RFC 6455)
python3-terminado - Terminals served to term.js using Tornado websockets (Python 3)
python3-websocket - WebSocket client library - Python 3.x

And you now know that you can install python3-websocket - WebSocket client library - Python 3.x

sudo apt-get install python3-websocket

This will also make sure the package is managed by your OS package manager and will update this package if it is necessary.

Yes, that would maybe be the correct way. But with limited Linux knowledge (and interest…) I take the “google way” and find solutions

ve2dsk · December 10, 2023, 6:47pm

Hi…
I just add this
export PYTHONPATH=/usr/local/lib/python3/dist-packages/
to the .bashrc file.
Seem patch the problem for now… VE2DSK

ve2dsk · April 27, 2024, 11:46pm

Hi,
is gr-satellite v5.5.0 compatible with satnogs client v1.8.1 (and Gnuradio v3.8.2) (bullseye)

Desperate and have no succes installing from source…
cmake 2.4.1 came with error
cmake 3.11 latest, came with non compatible error
cmake 2.8.1 came with different error

VE2DSK

PE0SAT · April 28, 2024, 6:50am

No, you need to use the maint-3.8 branch from gr-satellites.

git clone https://github.com/daniestevez/gr-satellites.git
cd gr-satellites
git branch
git checkout maint-3.8

Hi
(monitoring journalctl) I saw kill process after each observation. Is this normal…?

That just means that gr_satellites has quit early, probably with message “Satellite xxxxx not found”.
In my later development I have skipped the entire pre-check if the satellite is supported or not, gr_satellites will just quit gracefully if it cannot find satyaml for it.

ve2dsk · May 2, 2024, 10:44pm

Hi,
gr_satellite seem woking at this time…
Many thank for the info. VE2DSK

SA2KNG · May 3, 2024, 6:12pm

If you want to know what is going on, cat the grsat_xxxxx.log during the obs (located in /tmp/.satnogs/ by default), they will get deleted after the obs is finished. try: cat /tmp/.satnogs/grsat_*.log or if you want to keep the logs and look at them afterwards, set GRSAT_KEEPLOGS=yes, but don’t keep that enabled as it will fill up /tmp

I have looked into the journalclt of the SatNOGS Client, and it seems that I am facing the same problem:

Here is the log file, maybe this helps:

Traceback (most recent call last):
  File "/usr/local/bin/gr_satellites", line 317, in <module>
    main()
  File "/usr/local/bin/gr_satellites", line 302, in main

    self.mobitex = tnc_nx.nx_decoder(syncword, nx)
TypeError: make() takes 0 positional arguments but 2 were given

As far as I can see, this is related to gr-tnc_nx, which i was never able to install sucessfully. I have tried to install it for decoding of the BEESAT satellites: https://git.tu-berlin.de/rft/com/mobitub-2

According to the installation process it worked without any errors, but in operation it doesn’t.

PE0SAT · May 3, 2024, 8:46pm

All satellites that use Mobitex depend on gr-tnc_nx, so these will fail if it isn’t installed.
Mobitex support will only work with GNURadio 3.8 and the correct branch (GitHub - daniestevez/beesat-sdr at maint-3.8)

Only satellites that are part of the list gr_satellites -list_satellites will be decoded by gr-satellites.

Some questions up front

Did you build gr-satellites from source or used a repository?
What GNURadio version are you using?

Hi there…
looking at the LOG during pass give me, i beleive, bad syntax on main grsat script.
