Thank you for the tip. So people are definitely using USRP as a GPS receiver with the DBSRX. I knew this was somewhere out there, but I couldn't pin the location down.
As Feng pointed out to me, the RFX1200 does not have the proper frequency range to record/transmit on the L1 frequency of 1575 MHz. My understanding of GPS (fairly limited) says I need to handle a 2 MHz bandwidth, or 1574-1576 MHz to read the C/A code. So the RFX1800 should be able to handle this?
