Recording of ESCAPADE X-band telemetry with the Allen Telescope Array shortly after launch

Description

This dataset contains an IQ recording of the X-band telemetry signals from the ESCAPADE-Blue and ESCAPADE-Gold spacecraft done with the Allen Telescope Array the day after launch. Antennas 1b and 3c from the ATA were used in dual linear polarization (X and Y polarizations), but only the data from antenna 3c is included in this dataset.

The hardware configuration was as follows: the antennas were connected to RFCB LO d, which was tuned to a frequency of 8420 MHz and used an output IF of 512 MHz. A USRP N321 digitized both polarizations of antenna 1b, and a USRP N320 digitized both polarizations of antenna 3c. The USRP used an external 10 MHz reference and PPS coming from the observatory distribution system, and LO sharing was set up among the four channels. The IQ sample rate of the USRP was 10.24 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 signals of each spacecraft were downsampled to 512 ksps 8-bit IQ to reduce the size, and formatted in SigMF.
