The Portland State Aerospace Society (PSAS) is building ultra-low-cost, open source rockets and satellites that feature some of the most sophisticated amateur rocket avionics systems. Nearly all of the PSAS rocket designs, schematics, and code they develop are published on GitHub.

PSAS is currently working on the exciting open source OreSat cubesat project to give Oregon educators free access to satellite imagery:

Here's an exploded view of OreSat0, showing the internal cards, frames, solar panels, and turnstile antenna.
