Very nice work Marcus!
We’re working on various images of the sky too. I’ve now got 4
horns running simultaneously
making transit observations at different elevations.
These all use
gnu radio for the data takings software and run on
Raspberry Pi 4s in computer boxes
at the base of each horn. We need scans spaced by
about 5 degrees elevation, so
takes 23 scans, divided by 4 telescopes, = 6 days.
Plus calibration observations.
We now have a central host that has a GPS receiver
and provides a NTP timing reference
to each of the Pis. All are now powered over
ethernet, so only one ethernet cable to each horn.
The code and documentation is all at
and analysis which is really, not a part of
gnu-radio, at
Regards

PS What software are you using for gridding/mapping?
A collection of "Ad Hoc" stuff. The piece of code that runs every
