SatNOGS Client Development
This page describes the setup of a development environment for the SatNOGS ground station reference setup based on satnogs-client-ansible. It is assumed you have already setup your ground station as explained in SatNOGS_Client_Ansible.
gr-satnogs and gr-satnogs-package
The gnuradio Out-Of-Tree module gr-satnogs is packaged by gr-satnogs-package. The gitlab-CI automatically builds the package in docker containers as nightlies and on each release (git-tag, e.g. gr-satnogs_1.3-1_armhf.deb), configured by the .gitlab-ci.yml.
To use a modified gr-satnogs module on a SatNOGS ground station, it’s recommended to build it using the gr-satnogs-package scripts. Otherwise you can build gr-satnogs manually and adjust the installation paths to match the paths specified by gr-satnogs-package.
Building gr-satnogs with gr-satnogs-package can be automated via gitlab-CI, so that binary releases of your modified gr-satnogs module are available to download and install by the satnogs-client-ansible scripts (
- Fork gr-satnogs
- Fork gr-satnogs-package
- Adjust the repository url of gr-satnogs in gr-satnogs-package/debian/debian/rules#L22
- Adjust the repository url in the version detection in gr-satnogs-package/.gitlab-ci.yml#L13 ,#L30 ,#L47
- Wait for the gitlab-CI to build your first version of gr-satnogs-package (~45 min)
- Install your freshly built gr-satnogs-package by pointing the
SATNOGS_RADIO_GR_SATNOGS_PACKAGEin satnogs-setup to the built artifact/debian package of your architecture (e.g.
amd64). The build artifacts are available in your gr-satnogs-package fork by clicking CI/CD, selecting there the latest pipeline, the latest build-job and then in the right column
The satnogs-client is a python package, and gets installed by satnogs-setup in a python virtual environment using pip.
The development branch for the current releases 0.x is named
0. It's the original client implementation and features a local web interface.
A new implementation which aimed at a more modular architecture and doesn't include the local web interface anymore is developed in the
master branch (currently stale as of 2018-07-13).
Please note that satnogs-client and gr-satnogs must be installed in compatible versions, due to (frequent) changes in the arguments available in the demodulation scripts, see Compatibility.
