The payload will augment existing GNSS constellations with additional navigation signals from LEO, while relying on GNSS for orbit determination and time synchronization. FLORIAN KUNZI, BENJAMIN BRAUN, MARKUS MARKGRAF, OLIVER MONTENBRUCK, GERMAN AEROSPACE CENTER (DLR) / GERMAN SPACE OPERATIONS
This study examines the frequency, type and severity of interference events at specific locations in the country, providing valuable insights into the use of detectors, the nature of interference encountered, their potential sources and the impact on GNSS-derived positions. NURAG RAGHUVANSHI, SUNIL

In the past decade, there has been a sharp increase in GNSS outages due to deliberate GNSS jamming. Receivers in LEO are uniquely situated to detect, classify and geolocate terrestrial GNSS jammers. This article explores two-step and direct geolocation of terrestrial GNSS jammers from LEO. ZACHARY
