Abstract:	Given the increasing number of critical applications relying on GNSS, GNSS spectrum monitoring is becoming more and more crucial. Monitoring from low Earth orbit (LEO) has been investigated, and interference-source geolocalization has been demonstrated. In this paper, results are shown from the Bobcat-1 CubeSat mission which recorded multi-GNSS measurements but was not optimized for spectrum monitoring. The analysis of signal power metrics performed in this work suggests that non ad-hoc GNSS measurements from LEO could be exploited for GNSS spectrum monitoring.
