Welcome to CASPER, the Collaboration for Astronomy Signal Processing and Electronics Research. We are a group of scientists and engineers producing resources to aid in astronomy research.


Registration for the 2022 CASPER Workshop is now open!

We are pleased to announce that registration for the 2022 CASPER workshop is now open! This will be the first CASPER conference with in-person attendance since 2019 – we look forward to seeing as many CASPERites there as possible. Discounted early registration is available until the end of June, so head to the Conference Website to sign up!

Dates: 5-9th September 2022

Location: Cagliari, Italy

Head to the Conference Website for more information!


The primary goal of CASPER is to streamline and simplify the design flow of radio astronomy instrumentation by promoting design reuse through the development of platform-independent, open-source hardware and software.

Our aim is to produce tools which allow astronomers to rapidly design and deploy new instruments using FPGA, GPU, and CPU processors.

CASPER has members all around the world, and our hardware and software is used by dozens of experiments — check out the variety of CASPER instruments and their results in the scientific literature, or the 2016 CASPER overview paper.

Members of the CASPER collaboration typically meet once per year in a community workshop, where academics and engineers present their work and teach newcomers how to use CASPER tools.
