<p>This dataset contains a recording of X-band telemetry signals from the Chinese lunar sample retrieve mission Chang'e 5 done on 2020-11-28 before the LOI-1 (lunar orbit injection 1) manoeuvre that inserted the spacecraft into an elliptical lunar orbit. The recording was done at Allen Telescope Array using antenna 1h in dual XY (linear) polarization.</p>
<p>The hardware configuration was as follows: antenna 1h was connected to RFCB LO d, which was tuned to a frequency of 8463.7 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 an external 10 MHz reference and PPS coming from the observatory distribution system. The IQ sample rate of the USRP was 1.92 Msps. A GNU Radio flowgraph was used to record IQ samples to disk.</p>
<p>The GNU Radio flowgraph stored the IQ data for each channel as 16-bit 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 converted to <a href="https://github.com/gnuradio/SigMF">SigMF</a> format.</p>
<p>This dataset contains the IQ data for the Y polarization. The original metadata headers are also provided. The X polarization can be found in <a href="https://zenodo.org/record/4315066">this dataset</a>.</p>
