ADALM-Pluto AD9363 & Zync FPGA Development

ADALM-Pluto has AD9363 transceiver and Zync 7010 FPGA. I need help to use Zynq FPGA's ARM9 to configure AD9363 to down convert 1.5GHz GPS signal to base band 12bit I/Q output; shift multiply by 2 in FPGA, then send the I/Q signal back to AD9363 and remodulate back to 1.5GHz, such that when below setup (a) can get GPS position fix, the GPS signal passing through setup (b) ADALM-Pluto can also get GPS position fix.

(a) active antenna -> GPS receiver

(b) active antenna -> LNA -> ADALM-Pluto -> GPS receiver
