China develops UAV defenses from spoofing detection to covert links and shipboard landing

Unmanned aerial vehicles are rapidly advancing as tools for agriculture, logistics, surveillance, and disaster response, yet their reliance on GPS, wireless communications, and complex landing maneuvers leaves them open to manipulation, interception, and operational hazards. Three new papers in the Chinese Journal of Aeronautics detail Chinese teams' efforts to address these challenges with low-cost, practical solutions.

Researchers from Beijing University of Posts and Telecommunications (BUPT) and Pengcheng Laboratory introduced the Motion-State-Series Trajectory Prediction and Online Anomaly Detection (MSSTP-OAD) system to combat GPS spoofing.

By training a stacked LSTM on flight logs to forecast short-term motion, the system detects anomalies in real time through a two-stage ensemble
