GNSS Metadata Integrity in Consumer Smartphones During Commercial Flights: GPS Spoofing Artifacts, JPEG Tampering Detection, and Implications for UAV Precision Agriculture

Geomatics
Smartphone GNSS metadata remains an underexplored source for evaluating navigation-signal integrity in real-world conditions. We investigated GPS behavior recorded by a Samsung Galaxy A72 smartphone across two European flights (EXP03: Rome–Bucharest, n =

Performance of Receiver Autonomous Integrity Monitoring (RAIM) for Vertically Guided Approaches. (Etude de la Performance du Contrôle Autonome d'Intégrité pour les Approches à Guidage Vertical).

, 2008
The International Civil Aviation Organization (ICAO) has recognized the Global Navigation Satellite System (GNSS) as a key element of the Communications, Navigation, and Surveillance / Air Traffic Management (CNS/ATM) systems as well as a foundation upon which States can deliver improved aeronautical navigation services. But civil aviation requirements

Receiver Autonomous Integrity Monitoring (RAIM) Capability for Sole-Means GPS Navigation in the Oceanic Phase of Flight

IEEE Aerospace and Electronic Systems Magazine, 1992
Receiver autonomous integrity monitoring (RAIM), a GPS integrity monitoring scheme that uses redundant ranging signals to detect a satellite malfunction that results in a large range error, involves two functions: detection of the presence of a malfunctioning satellite and identification of which satellite (or satellites) is malfunctioning. An analysis
