SETI / Breakthrough Listen REU 2021 materials
CC0-1.0 License
This repository contains miscellanous materials used with the SETI and Breakthrough Listen Research Experience for Undergraduates summer programs. The material was elaborated in the context of the collaboration between GNU Radio and SETI Institute.
ata-control
contains a Jupyter notebook that teaches how to control the ATA
using the ata_control
Python module from
ATA-Utils. This was used together
with Hydrogen_line_ZMQ
to set up an activity where the students could freely
observe different parts of the Hydrogen line of the Milky Way.
gr-ata
contains a simple flowgraph done as a demo of how the
gr-ata block can be used to control
the ATA.
Hydrogen_line_ZMQ
contains a ZMQ server that streams IQ data from the USRPs
of the ATA GNU Radio
backend and a client that
plots the Hydrogen line spectrum.
interferometry
contains a demostration of two-antenna interferometry, including
concepts such as lag domain and fringe rate. There is a simulation flowgraph and
a live demo with the ATA.
live-spectrum.py
is used to send a real time spectrum from the USRPs over ZMQ.
This contains the client and the server flowgraphs.
Tianwen-1
uses this recording
done with Allen Telescope Array of the Chinese Mars orbiter Tianwen-1 and shows how
to decode the digital information transmitted by the spacecraft. This needs
gr-satellites installed.
Voyager1_GBT
uses a Voyager-1 recording from Green Bank Telescope to show
how to compute spectrum and waterfall data with GNU Radio
