# gr-satellites [](https://github.com/daniestevez/gr-satellites/releases/latest) [](https://anaconda.org/conda-forge/gnuradio-satellites) [](https://gr-satellites.readthedocs.io/) [](https://github.com/daniestevez/gr-satellites/blob/main/LICENSE) gr-satellites is a GNU Radio out-of-tree module encompassing a collection of telemetry decoders that supports many different Amateur satellites. This open-source project started in 2015 with the goal of providing telemetry decoders for all the satellites that transmit on the Amateur radio bands. It supports most popular protocols, such as AX.25, the GOMspace NanoCom U482C and AX100 modems, an important part of the CCSDS stack, the AO-40 protocol used in the FUNcube satellites, and several ad-hoc protocols used in other satellites. This out-of-tree module can be used to decode frames transmitted from most Amateur satellites in orbit, performing demodulation, forward error correction, etc. Decoded frames can be saved to a file or displayed in hex format. For some satellites the telemetry format definition is included in gr-satellites, so the decoded telemetry frames can be printed out as human-readable values such as bus voltages and currents. Additionally, some satellites transmit files such as JPEG images. gr-satellites can be used to reassemble these files and even display the images in real-time as they are being received. gr-satellites can be used as a set of building blocks to implement decoders for other satellites or other groundstation solutions. Some of the low level blocks in gr-satellites are also useful for other kinds RF communications protocols. ## Documentation gr-satellites [documentation](https://gr-satellites.readthedocs.io/) is hosted in [reathedocs.io](https://readthedocs.io/). ## Releases and branches Currently there are the following series of releases in the history of gr-satellites: * `v5.x.y` is the current release series, and supports GNU Radio 3.10. * `v4.x.y` had the same functionality as the v5.x.y series, but supported GNU Radio 3.9 (until v4.6.0, the v4.x.y series supported both GNU Radio 3.9 and 3.10). This branch was frozen on 2025-07-31, ending gr-satellites support for GNU Radio 3.9. * `v3.x.y` had the same functionality as the v5.x.y series, but supported GNU Rado 3.8. This series was the result of a large refactor that introduced a lot of new functionality and improvements. The refactor started on September 2019 and was finished in May 2020. This branch was frozen on 2025-07-31, ending gr-satellites support for GNU Radio 3.8. * `v2.x.y` is a series of releases compatible with GNU Radio 3.8 that existed between September 2019 and May 2020. The functionality in this series is equivalent to the `v1.x.y` series. * `v1.x.y` the original series of releases, which was compatible with GNU Radio 3.7. Development in this series stopped on September 2019 with the appearance of the `v2.x.y` line, but some bugfix releases have been published afterward. The repository is organized in the following branches: * `main` is where the active development happens. From time to time, features will be frozen in a new release. This branch is compatible with GNU Radio 3.10. * `maint-3.10` is the branch where releases in the current `v5.x.y` line are published. This branch is compatible with GNU Radio 3.10. * `maint-3.9` is the branch where releases in the current `v4.x.y` line were published. This branch was compatible with GNU Radio 3.9. The branch was frozen on 2025-07-31. * `maint-3.8` is the branch where releases in the current `v3.x.y` line were published. This branch was compatible with GNU Radio 3.
