Over last day and a half I've been comparing the 10Mhz output of my Jupiter based GPSDO (actually a G3RUH GPSDO) to a BVA OCXO. So far I don't see anything un expected. That being said I recognize that it would take a fairly significant disruption in the GPS signal for the affects to be noticeable in the 10 Mhz output.
