Summary: An open-source software-defined GNSS receiver

Development: https://github.com/gnss-sdr/gnss-sdr

Documentation: https://gnss-sdr.org/docs/

This program is a software-defined receiver which is able to process (that is, to perform detection, synchronization, demodulation and decoding of the navigation message, computation of observables, and, finally, computation of position fixes) the following Global Navigation Satellite System's signals: In the L1 band:

- GLONASS L1 C/A (centered at 1602.000 MHz)
- GPS L1 C/A (centered at 1575.420 MHz)
- Galileo E1b/c (centered at 1575.420 MHz)
- BeiDou B1I (centered at 1561.098 MHz)

In the E6 band:

- Galileo E6B (centered at 1278.750 MHz)

In the L2 band:

- BeiDou B3I (centered at 1268.520 MHz)
- GLONASS L2 C/A (centered at 1246.000 MHz)
- GPS L2C (centered at 1227.600 MHz)

In the L5 band:

- Galileo E5b (centered at 1207.140 MHz)
- Galileo E5a (centered at 1176.450 MHz)
- GPS L5 (centered at 1176.450 MHz)

GNSS-SDR provides interfaces for a wide range of radio frequency front-ends and raw sample file formats, generates processing outputs in standard formats, allows for the full inspection of the whole signal processing chain, and offers a framework for the development of new features.

Installing gnss-sdr

Installing gnss-sdr from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, gnss-sdr, volk-gnss-sdr can be installed with conda:

conda install gnss-sdr volk-gnss-sdr

or with mamba:

mamba install gnss-sdr volk-gnss-sdr

It is possible to list all of the versions of gnss-sdr available on your platform with conda:

conda search gnss-sdr --channel conda-forge

or with mamba:

mamba search gnss-sdr --channel conda-forge

Alternatively, mamba repoquery may provide more information:

# Search all versions available on your platform:
mamba repoquery search gnss-sdr --channel conda-forge

# List packages depending on `gnss-sdr`:
mamba repoquery whoneeds gnss-sdr --channel conda-forge

# List dependencies of `gnss-sdr`:
mamba repoquery depends gnss-sdr --channel conda-forge

About conda-forge

conda-forge is a community-led conda channel of installable packages. In order to provide high-quality builds, the process has been automated into the conda-forge GitHub organization. The conda-forge organization contains one repository for each of the installable packages. Such a repository is known as a feedstock.

A feedstock is made up of a conda recipe (the instructions on what and how to build the package) and the necessary configurations for automatic building using freely available continuous integration services. Thanks to the awesome service provided by Azure, GitHub, CircleCI, AppVeyor, Drone, and TravisCI it is possible to build and upload installable packages to the conda-forge anaconda.org channel for Linux, Windows and OSX respectively.

To manage the continuous integration and simplify feedstock maintenance conda-smithy has been developed. Using the conda-forge.yml within this repository, it is possible to re-render all of this feedstock's supporting files (e.g. the CI configuration files) with conda smithy rerender.

For more information please check the conda-forge documentation.

Terminology

feedstock - the conda recipe (raw material), supporting scripts and CI configuration.

conda-smithy - the tool which helps orchestrate the feedstock. Its primary use is in the construction of the CI .yml files and simplify the management of many feedstocks.

conda-forge - the place where the feedstock and smithy live and work to produce the finished article (built conda distributions)

Updating gnss-sdr-feedstock

If you would like to improve the gnss-sdr recipe or build a new package version, please fork this repository and submit a PR. Upon submission, your changes will be run on the appropriate platforms to give the reviewer an opportunity to confirm that the changes result in a successful build. Once merged, the recipe will be re-built and uploaded automatically to the conda-forge channel, whereupon the built conda packages will be available for everybody to install and use from the conda-forge channel. Note that all branches in the conda-forge/gnss-sdr-feedstock are immediately built and any created packages are uploaded, so PRs should be based on branches in forks and branches in the main repository should only be used to build distinct package versions.

In order to produce a uniquely identifiable distribution:

• If the version of a package is not being increased, please add or increase the build/number.
• If the version of a package is being increased, please remember to return the build/number back to 0.
