PICTOR: A free-to-use Radio Telescope


Hi all!

Over the past few months, I’ve been working on PICTOR.

PICTOR is an open-source radio telescope that allows anyone to observe the radio sky using its convenient web platform for free. The goal of this effort is to introduce students, educators, astronomers and others to the majesty of the radio sky, promoting radio astronomy education, without the need of building a large and expensive radio telescope by the user.

PICTOR consists of a 1.5-meter parabolic antenna that allows anyone to make continuous and spectral (i.e. hydrogen line) drift-scan observations of the radio sky in the 1300~1700 MHz regime for free.

For more information, please take a look at the Website: https://www.pictortelescope.com/, the GitHub repository: https://github.com/0xCoto/PICTOR (stars are appreciated!) and/or the PDF guide that includes some introductory information on radio astronomy as well as instructions on how to use the telescope:www.pictortelescope.com/Observing_the_radio_sky_with_PICTOR.pdf

All feedback is welcome and highly encouraged! :smiley:


Very cool!

I might try and do something similar using my LimeSDR Mini. To give a max of 30.72 MHz bandwidth between 30Mhz and 3.5Ghz (It supports down to 10 Mhz but its a bit odd with the NCO to do that.)

Just a problem of building antennas for that sort of stuff.


The antenna always depends on your goals: what do you wish to observe? Fainter radio sources in the sky obviously demand a greater antenna aperture to observe with a reasonable signal-to-noise ratio (S/N), so the antenna can be very small or very large, depending on your observation goals. :slight_smile:
