Funnily enough I have a legitimate use for this: correcting GPS drift in a location with poor GPS availability. I would love to carry around a Raspberry Pi with an attached SDR that let me fine tune the signal so it's accurate versus showing me across the street, down the block or aimlessly wandering in circles.
