“…General time difference of arrival (TDOA) and frequency difference of arrival (FDOA) interference localization has been extensively studied (Amar & Weiss, 2008; Bhatti, 2015; Griffin & Duck, 2002; Ho & Chan, 1997; Pattison & Chou, 2000), and such techniques have been applied for terrestrial interference localization from geostationary orbit (Haworth et al., 1997; Ho & Chan, 1993; Smith & Steffes, 1989). Application of TDOA or FDOA for localization from LEO can be viewed as an extension of such demonstrations, with the lower‐altitude orbits enabling the localization of much weaker signals.…”

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 the development of interference‐hardened GNSS receivers. This paper presents the results of a three‐year study of global interference, with emphasis on a particularly powerful interference source active in Syria since 2017. It then explores the implications of such interference for GNSS receiver operation and design.
