Observation of terrestrial GNSS interference (jamming and spoofing) from low-earth orbit (LEO) is a uniquely effective technique for characterizing the scope, strength, and structure of interference and for estimating transmitter locations. Such details are useful for situational awareness, interference deterrence, and for developing interference-hardened GNSS receivers. This paper explores the performance of LEO interference monitoring and presents the results of a three-year study of global interference, with emphasis on a particularly powerful interference source active in Syria since 2017.
