James Webb Space Telescope S-band recording with Allen Telescope Array (320 kHz bandwidth)

Abstract

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. 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. The GNU Radio flowgraph stored the IQ data for each channel as 16-bin integers in the GNU Radio metatata file format, with detached headers. After recording, the data was decimated to 320 ksps and converted to SigMF 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 "James Webb Space Telescope S-band recording with Allen Telescope Array (wideband excerpt)". Detached metadata files, with .hdr extension, contain the metadata for the original 3.84 Msps recording.
