Created a Marian Scientific KiCad project template that has a basic PCB with mounting holes, the minimum silkscreen info required per company standards, and a bunch of settings set up for both an in-house and professional board fabrication. Click here for the template.
Threw a quick GPS data display together using a Pi Zero (overkill, used only for the USB GPS dongle). It shows lat/long/alt/speed and the fix status and number of satellites observed.
