Hi Dave, You could try a shorter USB 3.0 cable, they can be as short as .2 meters. If running from a laptop, run the laptop from battery, reduces a radiating power cord and DC/DC charger/switch mode powersupplies from your setup.
Use a second laptop with/or dedicated spectrum analyser and RF probes to get an idea of the sources and power levels, and (sub) harmonics of clocks involved in your cabling setup, and determine how to might enter one of the GNSS bands and how you are going to attenuate them.
