Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, Volume 44, Issue 5, Page 594-606, September/October 2026.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency ( > 500 ms) and inadequate coverage at high latitudes,

Source Tracing: Detecting Voice Spoofing

, 2022
Recent anti-spoofing systems focus on spoofing detection, where the task is only to determine whether the test audio is fake. However, there are few studies putting attention to identifying the methods of generating fake speech.

GNSS Spoofing Detection by Supervised Machine Learning with Validation on Real-World Meaconing and Spoofing Data—Part II

Sensors, 2020
Global Navigation Satellite System (GNSS) meaconing and spoofing are being considered as the key threats to the Safety-of-Life (SoL) applications that mostly rely upon the use of open service (OS) signals without signal or data-level protection. While a

Lightweight Multilayer IoT Attack Detection: An Evaluation of the Semi‐Automated Intrusion Detection System (SAIDS) Framework on Simulated and Real‐World Traffic

SECURITY AND PRIVACY, Volume 9, Issue 5, September/October 2026.
ABSTRACT The rapid growth of the Internet of Things (IoT) creates concern around multilayer cyber‐attacks that exploit interactions between physical, network, and application layers. Traditional Intrusion Detection Systems (IDS) often utilize outdated datasets, high dimensional features, or computationally heavy deep learning models, which are not ...

Correlation of High‐Latitude Scintillation With Auroral Precipitation: Case Studies Using GNSS Radio Occultation Data From PlanetiQ

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This study presents a survey of high‐latitude ionospheric scintillation using GNSS radio occultation (RO) data from the PlanetiQ satellite. The analysis examines 483 high‐latitude RO tracks between January and May 2023, with 371 tracks exhibiting scintillation events.
