PROVES-Yearling is built on the PyCubed architecture and is intended to serve as a lab bench in space.


Yearling is carrying a spresense camera payload for attitude determination in addition to 3 IMUs. We have prioritized modularity and low-cost hardware to create a CubeSat kit that can be made available to other university CubeSat programs to provide a leg up in the development process.

The PROVES kit will contain an unassembled structure, the novel Lovelace flight computer architecture, and a software handbook. Universities will also be able to access the open source files for the entire kit as well. The kit aims to bridge the knowledge gap between what undergraduates are taught and the knowledge required to engineer a spacecraft. PROVES-Yearling and our following CubeSat, PROVES-X, are the first steps to accomplishing these goals.

Since then, the mission for PROVES has now expanded. We now plan to create an open-source 1U CubeSat kit that is versatile enough to meet most 1U missions. This kit will include the Lovelace architecture (Backplane, EPS, ADCS, & C&DH boards), sheet metal structure, and a complete software handbook. Overall, in addition to producing a satellite that will meet the Pleiades CubeSat Cluster mission's needs, Bronco Space will be creating a modular product as well.
