Hardware for OreSat's SDR GPS receive and other SDR GPS projects
The OreSat GPS Card provides two GPS receivers for the OreSat bus:
1. The SkyTraq Orion B16 which is a COTS GPS receiver capable of lock while in orbit. 2. The MAX2769 SDR GPS receiver. This hardware is for a future SDR capability we'd like to have, and might one day replace the much more expensive COTS receiver.
