DSPIRA telescope software

DSPIRA applications are GNU Radio flowgraphs. They describe how signal-processing blocks connect to form a spectrometer or another telescope instrument. The applications live in dspira-software. Their reusable radio_astro blocks are installed from gr-radio_astro.

Download the classroom applications

Download the application files as a ZIP

Extract the ZIP and open its flowgraphs folder. The collection includes a calibrated spectrometer, two interferometers, and four experimental lightning detectors.

The repository move preserved these files unchanged. Current GNU Radio checks found existing compatibility errors. Review the compatibility findings before using them in class. Receiver operation and calibration have not been verified for this migration.

Install the shared blocks

Follow the installation lesson to prepare GNU Radio and the shared library. Then open the desired application from the downloaded flowgraphs folder. Choose the receiver, output folders, and calibration settings for your equipment.

The shared library remains in gr-radio_astro. It also supports astronomy applications outside DSPIRA. Install it once; the classroom repository does not contain another copy.

Update or contribute

Application changes belong in dspira-software. Reusable block changes belong in gr-radio_astro. Include the GNU Radio version, receiver model, and test results with a software contribution.

For a lesson or worksheet, use the teacher contribution guide. For schematics and fabrication files, use the hardware guide.

Find an older download

The repository map lists replacement addresses for files moved from the shared library. Historical releases and commit links retain their original files. Older GNU Radio 3.8 instructions refer to the separate gr38 release line.
