The AMSAT Fox engineering team has completed the design of the printed circuit boards for the satellite’s “Z” solar panels. Each of these printed circuit boards (PCBs) will accommodate two Boeing/Spectrolab UTJ solar cells. There is a hole in the panel for the lens of the Camera module that is being developed by Virginia Tech. A sample PCB was fabricated and sent to our partner SpaceQuest who approved it for manufacturing into our solar panels.

Fox-1 prepares to catch some rays. Just pull the RBF pin!
