Track-Consistency-Based GNSS RFI Monitoring Using Crowdsourced ADS-B Sensor Networks
Sanghyeon Park, Halim Lee, Pyo-Woong Son
Growing reports of global navigation satellite system (GNSS) radio-frequency interference (RFI) highlight the need for scalable wide-area sensing for situational awareness. Crowdso…
Wide-Area GNSS Interference Monitoring with CYGNSS GNSS-R Delay-Doppler Noise Floor Observations
Ji-Hyeon Shin, Pyo-Woong Son
Global Navigation Satellite System (GNSS) interference increasingly threatens positioning, navigation, and timing services and requires monitoring over areas beyond dense ground ne…
Path-Based Correlation Analysis of Meteorological Factors and eLoran Signal Delay Variations
Junwoo Song, Pyo-woong Son
Unlike GNSS, which is vulnerable to jamming and spoofing due to its inherently weak received power, eLoran exhibits robustness owing to its high field strength. Therefore, the eLor…
Performance Evaluation of eLoran Spatial ASF Corrections Based on Measured ASF Map
Jaewon Yu, Pyo-Woong Son
This paper analyzes the effectiveness of spatial ASF correction methods in the Korean eLoran system using measured ASF maps. Three correction scenarios were evaluated under identic…
Correlation Analysis Between MF R-Mode Temporal ASF and Meteorological Factors
Jongmin Park, Junwoo Song, Taewon Kang +2
As the vulnerabilities of global navigation satellite systems (GNSS) have become more widely recognized, the need for complementary navigation systems has grown. Medium frequency r…
Enhancing eLoran Timing Accuracy via Machine Learning with Meteorological and Terrain Data
Taewon Kang, Seunghyeon Park, Pyo-Woong Son +1
The vulnerabilities of global navigation satellite systems (GNSS) to signal interference have increased the demand for complementary positioning, navigation, and timing (PNT) syste…
