From the project
Hardware for OreSat's SDR GPS receive and other SDR GPS projects
This is the repo for our OreSat GPS Card. For software, see the oresat-gps-software repo.
A SkyTraq Orion-B16 GNSS module, a GNSS receiver module meant for university CubeSat use. An Analog Devices MAX2771 SDR GNSS receiver IC that is read by the Octavo OSD335x-SM processor's PRU and then parsed using the GNSS-SDR project software.
TRL 6-7 ish. Flown, but not yet demonstrated to work in space.
