The CubeSat standard sprang from the desire to create a satellite standard that would open the doors for universities and other lower budget research institutions by making it more feasible to get their work into space. Since then, many other institutions and industries have been adopting variations on the standard for their own use. As more people are seeking out to use the CubeSat standard as their main bus, the standards and practices of the community have grown and expanded and with this growth, new challenges have been created. One such challenge is the bandwidth limitation in the RF-downlink. When carrying payloads requiring what might seem to be a relatively small (science data) bandwidth requirement (on the order of thousands of bps), the RF-link to ground is overloaded. Many approaches in the past have been put forth to help alleviate this issue, unfortunately, none have been fully adopted. This paper presents a solution that takes advantage of new technology yet to be fully exploited in space applications. The key to the solution lies in removing the bandwidth requirements by enabling onboard post-data processing and compression. In order to achieve the high computational needs, while minimizing power consumption, a Xilinx Zynq-7000 SoC is used, creating a highly-programmable, open integration device. This report outlines the design, fabrication and testing of this solution. The completion of the Zynq Processing System CubeSat Science Instrument Interface Electronics Board (or ZPS-Board), ultimately demonstrates the feasibility of this solution. Additionally, this research is funded by NASA’s JPL, with secondary motives for the creating of a space application Zynq-7000 SoC based product. Upon successful completion of the ZPS-Board, the product creates a platform for JPL to perform environmental testing in order to study the effects and performance characteristics of the Zynq in space applications.
