James Webb Space Telescope S-band recording with Allen Telescope Array (320 kHz bandwidth)
<p>This dataset contains a recording of the S-band telemetry downlink of James Webb Space Telescope. The recording was done on 2021-12-26, roughly one day after launch, using Allen Telescope Array antenna 2e in dual XY (linear) polarization.</p> <p>The hardware configuration was as follows: antenna 2e was connected to RFCB LO d, which was tuned to a frequency of 2270.5 MHz and used an output IF of 512 MHz. A USRP N321 was connected to the IF output of the RFCB and digitized both polarizations. The USRP used external 10 MHz reference and PPS coming from the observatory distribution system. The IQ sample rate of the USRP was 3.84 Msps and a GNU Radio flowgraph was used to record IQ data to disk.</p> <p>The GNU Radio flowgraph stored the IQ data for each channel as 16-bin integers in the <a href="https://wiki.gnuradio.org/index.php/Metadata_Information">GNU Radio metatata file format</a>, with detached headers. After recording, the data was decimated to 320 ksps and converted to <a href="https://github.com/gnuradio/SigMF">SigMF</a> format. By using 320 ksps, residual carrier and 80 kbaud PCM/PM/NRZ telemetry modulation are still present in decimated recording. However, the sequential ranging tones are outside of the decimated recording passband. An excerpt of the full 3.84 Msps recording, which contains the sequential ranging tones, is published as the dataset "<a href="https://zenodo.org/record/5812277#.YdHytoqCGCg">James Webb Space Telescope S-band recording with Allen Telescope Array (wideband excerpt)</a>". Detached metadata files, with .hdr extension, contain the metadata for the original 3.84 Msps recording.</p>

Radio telescope (antenna)
Radio telescope (antenna) about 1970, Louvain-la-neuve (Belgium). Made out 500 pictures taken with a Galaxy S9 and 3D reconstruction with Zephyr3D Lite from 3DFlow. A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects.

Recording of Hera X-band telemetry with the Allen Telescope Array shortly after launch (part 2/2)
<p>This dataset contains an IQ recording of the X-band 8435.8 MHz telemetry signal from the Hera spacecraft done with the Allen Telescope Array starting 1 hour and 30 minutes after launch. Antenna 1a from the ATA was used in dual linear polarization (X and Y polarizations).</p> <p>The hardware configuration was as follows: the antenna was connected to RFCB LO d, which was tuned to a frequency of 8435.75 MHz and used an output IF of 512 MHz. A USRP N321 digitized both polarizations of each antenna. The USRP used an external 10 MHz reference and PPS coming from the observatory distribution system, and LO sharing was set up among the two channels. The IQ sample rate of the USRP was 6.144 Msps, and a GNU Radio flowgraph was used to record IQ data to disk. The GNU Radio flowgraph stored the IQ data for each channel as 16-bin integers in the <a href="https://wiki.gnuradio.org/index.php/Metadata_Information">GNU Radio metatata file format</a>, with detached headers. The header files are included in the dataset as .hdr files.</p> <p>After recording, the data was downsampled to 2.048 Msps 8-bit IQ to reduce the size, and formatted in <a href="https://github.com/gnuradio/SigMF">SigMF</a> with the script do_sigmf.py (contained in part 1/2).</p> <p>Antenna pointing was done manually by trying to maximize the received signal power, since the ephemerides publicly available when the launch happened differed greatly from the true launch trajectory. As a consequence, there is signal fading when the antenna is not pointed correctly.</p> <p>This dataset is part 2/2. It contains a recording of the high rate telemetry signal. <a href="https://zenodo.org/records/14060729">Part 1/2</a> contains two recordings of the low rate telemetry signal.</p>
Cygnus A 8.45 GHz interferometric observation with Allen Telescope Array
<p>This dataset corresponds to an interferometric observation that was done in the context of the GNU Radio community activities at Allen Telescope Array. The observation was carried out using a GNU Radio FX software correlator and two USRP N32x SDR transceivers, as well as some custom code for phasing and data reduction.</p> <p>Cygnus A and some compact sources (3C84, 3C286, J2007+404) were observed over three days between 2021-07-23 and 2021-07-25 using 6 antennas from the array. The observation frequency was 8.45 GHz. Two USRP N32x were connected to the 512 MHz IF output of the RFCB LO d. Each USRP digitized the two polarizations of one antenna. This setup requires baselines to be iterated one at a time for interferometric observing. The observing bandwidth was 40.96 MHz.</p> <p>An FX correlator with 2048 channels and an integration time of 0.1 seconds was implemented in GNU Radio. The drifting correlations were then phased to each source in post processing. CASA was used for calibration and imaging.</p> <p>This post contains the following files:</p> <ul> <li>ATA-20210723.tar, ATA-20210724.tar, and ATA-20210725.tar contain the phased correlator output for each of the days in UVFITS format, reduced to a rate of 1 second and 64 channels</li> <li>CASA-masks.tar contains CLEAN masks to be used with CASA and <a href="https://github.com/daniestevez/ata_interferometry/blob/main/CASA/CygA_2020724.py">this script</a> to reproduce the whole CASA pipeline starting from the UVFITS files</li> <li>CASA-images.tar contains CLEAN images and self-calibrated CLEAN images for all of the sources in FITS format, as well as the ancialliary files produced by CASA during tclean</li> </ul> <p>The raw FX correlator output is not included in this dataset because of size constraints.</p> <p>More information about this observation and the processing pipeline can be found in the post "<a href="https://destevez.net/2021/08/imaging-cygnus-a-at-8-45-ghz-with-ata/">Imaging Cygnus A at 8.45 GHz with ATA</a>" by the author.</p>

Antennas 1a and 5c from the Allen Telescope Array were used in dual XY (linear) polarization.</p> <p>The hardware configuration was as follows: the antennas were connected to RFCB LO d, which was tuned to a frequency of 8451.5 MHz and used an output IF of 512 MHz. A USRP N321 and a USRP N320 were connected to the IF output of the RFCB. The USRP N321 digitized both polarizations of antenna 1a, while the USRP N320 digitized both polarizations of antenna 5c. The USRPs used an external 10 MHz reference and PPS coming from the observatory distribution system, and LO sharing was set up among all the channels. The IQ sample rate of the USRPs was 1.92 Msps, and a GNU Radio flowgraph was used to record IQ data to disk. The GNU Radio flowgraph stored the IQ data for each channel as 16-bin integers in the <a href="https://wiki.gnuradio.org/index.php/Metadata_Information">GNU Radio metatata file format</a>, with detached headers.</p> <p>After recording, the data was converted to <a href="https://github.com/gnuradio/SigMF">SigMF</a> format. The detached headers are also provided in the dataset (they have the .hdr extension).</p> <p>There are two recordings in this dataset. In the first one, LunaH-Map is transmitting a PCM/PM/bi-phase-L signal at approximately 48 kbaud. In the second one, LunaH-Map is transmitting a PCM/PM/NRZ signal at approximately 255 kbaud.</p> <p>Since the second recording doesn't have good enough SNR for error-free decoding with a single antenna, the two antennas were beamformed by determining the correct complex amplitude, delay and frequency offsets for the two antennas, and by correcting these parameters before adding the signals. The beamformed signal is provided in the HMAP_2022-11-16T15:16:06_beamform SigMF dataset. In this dataset, the signal polarization has been synthesized by finding the correct amplitude and phase offset between the X and Y channels of each antenna, and adding coherently both channels before beamforming.</p>
