USB3 circuitry is the source of annoying RF interference I badly experimented it, those past weeks, after moving my
system (boot & root) from an SD to an USB3.0 SSD. It became almost impossible to get any FIX !
When I saw that video I knew I was getting close to the source of my problems ...
Searching "USB3 interference" in the Raspberry Pi org web forum returned 974 matches !
The phenomenon is generic, not specific to the RPi4 : see this Intel whitepaper !
It affects many various domains : WiFi 2.4 GHz, Bluetooth, wireless keyboards & mice, and, of course GPS receivers !
How can we live with that ?
troubles, though I use a wireless Logitech keyboard (unifying dongle) !
Any other solution or suggestion ? Please POST !

- Dont use USB 3 if you are not obliged : Connecting my SSD to an USB2 port solved immediately the case.
Knowing that may save your boat and your life ...
- Move the receiver away from the RPi : moving from 0m90 to 1m80 was a significant relief in my case ...
I use a very common combined receiver with antenna (Ublox M8)
- Hey, I bought an expensive RPi4 to benefits from its USB 3 !!! So, I further improved the relief obtained in above
point 2 by an extra shielding of both the USB cable and SSD case with a chocolate aluminum foil (see picture)
